### User Notes:

- #### res ari: Add attachable states to Channels and Bridges

  Bridge variables now can be set and retrieved via the following paths: `/bridges/{bridgeId}/variable` `/bridges/{bridgeId}/variables` Both Bridge and Channel variables can now be set with an optional 'report_events' boolean flag that will cause those variables to be included on all events on that object. The 'report_events' flag will default to False if not set to maintain backwards capability. To allow this, variables can now be either name value pairs (the current format): `<variable_name>: '<value_string>'`

- or - `<variable_name>: {value: '<value_string>', report_events: [true|false]}`

- #### ARI: Added paths to get and set multiple channel variables.

  Added new ARI paths for getting and setting multiple channel variables at a time. For GET, this takes in a single string of comma-separated variable names, while POST takes in a dictionary of key value pairs. The behavior is the same as passing in variables when originating a channel.

- #### res_rtp_asterisk: Add option to control stun host resolution when TTL = 0

  A new `stunaddr_reresolve_ttl_0` parameter has been added to rtp.conf that allows control over what happens when a STUN server hostname lookup returns a TTL of 0. The values can be set as follows:

- 'no': This is the historical (and current default) behavior of not doing any further lookups and continuing to use the last successful result until Asterisk is restarted or rtp.conf is reloaded.
- 'yes': Use the last cached result for the current call but trigger re-resolution in the background for the benefit of future calls. If the result of the background lookup is a ttl > 0, periodic resolution will be restarted otherwise the next call will use the new cached value and will trigger a background lookup again. A new CLI command `rtp resolve stun hostname` has been added

- #### app_dial: Properly handle callee hangup while sending digits.

  If a called channel sends progress or wink and the caller begins sending digits but the callee answers and then hangs up before digit sending can finish, the call is now answered before being disconnected. If the callee hangs up without answering, the call now continues in the dialplan.

- #### Upgrade bundled pjproject to 2.17.

  Bundled pjproject has been upgraded to 2.17. For more information about what is included in this release, see the pjproject Github page: https://github.com/pjsip/pjproject/releases/tag/2.17

- #### res_pjsip: Add per-endpoint RTP port range configuration

  PJSIP endpoints now support rtp_port_start and rtp_port_end options to configure a dedicated RTP port range per endpoint, overriding the global rtp.conf setting.

- #### stasis_broadcast: Add optional ARI broadcast with first-claim-wins

  New optional modules res_stasis_broadcast.so and app_stasis_broadcast.so enable broadcasting an incoming channel to multiple ARI applications. The first application to successfully claim (via POST /ari/events/claim) wins channel control. StasisBroadcast() dialplan application initiates broadcasts. CallBroadcast and CallClaimed events notify applications. When modules are not loaded, behavior is unchanged.

- #### chan_iax2: Add CHANNEL getter to retrieve auth method.

  CHANNEL(auth_method) can now be used to retrieve the auth method negotiated for a call on IAX2 channels.

- #### res_pjsip_maintenance: Add PJSIP endpoint maintenance mode

  New module res_pjsip_maintenance adds runtime maintenance mode for PJSIP endpoints. Use "pjsip set maintenance " to enable or disable, and "pjsip show maintenance" to list affected endpoints. AMI actions PJSIPSetMaintenance and PJSIPShowMaintenance provide programmatic access. No configuration file changes required.

### Upgrade Notes:

- #### jansson: Upgrade version to jansson 2.15.0

  jansson has been upgraded to 2.15.0. For more information visit jansson Github page: https://github.com/akheron/jansson/releases/tag/v2.15.0

- #### res_pjsip: Add per-endpoint RTP port range configuration

  An alembic database migration has been added to add the rtp_port_start and rtp_port_end columns to the ps_endpoints table. Run "alembic upgrade head" to apply the schema change.

### Developer Notes:

- #### res_pjsip: Add per-endpoint RTP port range configuration

  New public API: ast_rtp_instance_new_with_port_range() creates an RTP instance with a per-instance port range. ast_rtp_instance_get_port_start() and ast_rtp_instance_get_port_end() allow RTP engines to query the override. Third-party RTP engines can use these getters to support per-instance port ranges.

- #### stasis_broadcast: Add optional ARI broadcast with first-claim-wins

  New public APIs in stasis_app_broadcast.h: stasis_app_broadcast_channel(), stasis_app_claim_channel(), stasis_app_broadcast_winner(), and stasis_app_broadcast_wait(). New ARI event types (CallBroadcast, CallClaimed) added to events.json. All code is isolated; no existing ABI modified.

- #### res_pjsip_maintenance: Add PJSIP endpoint maintenance mode

  ast_sip_session_supplement gains a new optional callback - int (session_create)(struct ast_sip_endpoint endpoint, const char *destination). It is called from the global supplement list (not per-session) at the start of ast_sip_session_create_outgoing() via ast_sip_session_check_supplement_create(). Returning non-zero blocks the outgoing session. Modules that need to gate outbound SIP session creation should register a supplement with this callback set rather than hooking into chan_pjsip directly.

- #### build: remove pjsua, pjsystest, Python bindings and asterisk_malloc_debug stubs from pjproject dev build

  The pjsua and pjsystest application binaries, the deprecated Python pjsua bindings (`_pjsua.so`), and the `asterisk_malloc_debug.c` stub implementations are no longer built or installed as part of the bundled pjproject dev mode build. The `PYTHONDEV` (python2.7-dev) build dependency is also removed. Developers who relied on the pjsua binary for Test Suite SIP simulation should use SIPp instead, which is the current Asterisk Test Suite standard. Fixes: #1840

### Commit Details:

#### res_ari: Add res_ari_model as an optional_module.

Author: George Joseph Date: 2026-06-03

Under certain timing/load conditions, res_ari_model may not load until after res_ari on startup or it might unload before res_ari on shutdown. This can cause a segfault when DEVMODE is enabled and there are persistent outbound websocket connections because DEVMODE forces validation of outgoing events against the models. To prevent this, res_ari_model has been added as an "optional_module" to res_ari's NODULE_INFO. This will enforce load/unload order but not make res_ari dependent on res_ari_model. However, if Asterisk is configured with --enable-dev-mode, res_ari will fail to load if res_ari_model isn't available.

Resolves: #1970

#### res ari: Add attachable states to Channels and Bridges

Author: Mike Bradeen Date: 2026-03-31

Adds the ability to attach multiple states to both Channels and Bridges in the form of variables that are included in all events on the associated object.

First, this adds an optional boolean field to channel variables 'report_events' that causes the variable to automatically be included in all events on that channel.

To allow this, variables can now be either name value pairs (the current format): `<variable_name>: '<value_string>'` - or - `<variable_name>: {value: '<value_string>', report_events: [true|false]}`

If the old format is used or 'report_events' is not included, it will default to false and retain current behavior.

Second, this extends both reported and unreported variables to Bridges so they too may have stateful information.

Resolves: #1910

UserNote: Bridge variables now can be set and retrieved via the following paths: `/bridges/{bridgeId}/variable` `/bridges/{bridgeId}/variables` Both Bridge and Channel variables can now be set with an optional 'report_events' boolean flag that will cause those variables to be included on all events on that object. The 'report_events' flag will default to False if not set to maintain backwards capability. To allow this, variables can now be either name value pairs (the current format): `<variable_name>: '<value_string>'` - or - `<variable_name>: {value: '<value_string>', report_events: [true|false]}`

#### ARI: Added paths to get and set multiple channel variables.

Author: Ben Ford Date: 2026-04-15

Two new paths exist for ARI to get and set multiple channel variables at the same time. This is done via GET and POST like the single get and set variable equivalents. Leading and trailing whitespace will be stripped from the variable names for both paths. When setting variables, the values will be read as-is, whitespace included. GET takes in a single string with comma-separated values, while POST takes in a dictionary of key value pairs. The code follows the same paths as when setting multiple variables when originating a channel via ARI.

UserNote: Added new ARI paths for getting and setting multiple channel variables at a time. For GET, this takes in a single string of comma-separated variable names, while POST takes in a dictionary of key value pairs. The behavior is the same as passing in variables when originating a channel.

#### res_stir_shaken: avoid direct ASN1_STRING accesses

Author: Bernd Kuhls Date: 2026-05-02

https://github.com/openssl/openssl/issues/29117

Signed-off-by: Bernd Kuhls bernd@kuhls.net

Resolves: #1952

#### tcptls.c: fix build with OpenSSL 4

Author: Bernd Kuhls Date: 2026-05-02

tcptls.c: In function '__ssl_setup': tcptls.c:417:52: error: implicit declaration of function 'SSLv3_client_method'; did you mean 'SSLv23_client_method'? [-Wimplicit-function-declaration] 417 | cfg->ssl_ctx = SSL_CTX_new(SSLv3_client_method());

SSLv3_client_method was removed from OpenSSL 4.0.0: https://github.com/openssl/openssl/blob/openssl-4.0.0/doc/man7/ossl-removed-api.pod?plain=1#L440

Resolves: #1952

#### res_calendar: Fix build with libical 4.X

Author: mikhail_grishak Date: 2026-05-26

libical 4.0 removed the icaltime_add() function in favor of icaltime_adjust(). Additionally, the callback signature for icalcomponent_foreach_recurrence() was updated to use a const pointer for the icaltime_span argument.

This commit adds conditional compilation using ICAL_MAJOR_VERSION to support both libical 3.X and the new 4.X API, ensuring backward compatibility.

Fixes: #1957

#### app_record: Fix hangup handling during beep playback

Author: UpBeta Date: 2026-05-23

When a hangup occurs while app_record is playing the initial beep, the application does not detect the hangup and continues running until the maxduration timeout expires.

Replace the manual ast_streamfile() + ast_waitstream() sequence with ast_stream_and_wait(), which properly detects hangup and returns non-zero, allowing the application to exit immediately with RECORD_STATUS set to HANGUP.

Resolves: #1950

#### odbc: Don't use prepared statements for distinct SQL statements

Author: smtcbn Date: 2025-04-25

Avoids unnecessary prepare for simple INSERT statements that cause issues with ProxySQL (prepared statement counter overflow).

Resolves: #1217

#### abstract_jb.c: Remove timerfd from channel when disabling jitter buffer

Author: Alexander Bakker Date: 2026-05-20

Previously, the lingering timerfd would cause a tight loop if the channel enters a BridgeWait after the jitter buffer was disabled.

Fixes: #1762

#### res_pjsip: Don't allow a leading period when wildcard matching

Author: Sean Bright Date: 2026-05-26

The reference identifier (what the client provides - in this case a hostname) must start with a domain label, not a `.`.

The current implementation will match `.seanbright.com` against `*.seanbright.com` which is incorrect.

#### Ensure channel locks aren't held while calling ast_set_variables.

Author: George Joseph Date: 2026-05-20

If the channel is locked when calling ast_set_variables and any of the variables contained dialplan functions, there's a possiblilty of a deadlock. To prevent this, either the explicit locks were removed or the call to ast_set_variables moved out of the lock scope. A warning to not hold channel locks is also added to the documentation for ast_set_variables.

Resolves: #1936

#### app_queue: fix double increment of member->calls with shared_lastcall

Author: smtcbn Date: 2026-01-23

Under high concurrency, update_queue() may be invoked multiple times for the same call, causing member->calls and queue-level counters to be incremented more than once.

The existing starttime check is not atomic and allows concurrent execution paths to pass. Treat member->starttime as a single-use token and consume it via CAS to ensure the call is counted exactly once.

This also prevents incorrect call distribution when using strategies such as fewestcalls.

Observed as a regression after upgrading to 20.17.

Resolves: #1736

#### chan_dahdi: Fix set but not used in mfcr2_show_links_of().

Author: George Joseph Date: 2026-05-21

When openr2 is installed mfcr2_show_links_of() is no longer ifdeffed out which makes gcc-16 complain with 'variable ‘x’ set but not used'.

Resolves: #1947

#### tests: add tests/test_codec_translations.c

Author: Sebastian Jennen Date: 2026-03-06

This tests checks [slin -> codec -> slin] and then compares slin in vs out regarding signal noise ratio and delay.

Near-lossless codecs (ulaw, alaw) are checked with a maximum per-sample error bound. Lossy codecs are checked with a per-codec SNR threshold. Cross-correlation alignment compensates for algorithmic delay in codecs like speex and opus.

Covered codecs: ulaw, alaw, adpcm, g726, g726aal2, gsm, speex, speex16, speex32, ilbc, codec2, lpc10, g722, opus.

Resolves: #1812

#### install_prereq: Add a 'minimal' mode for basic build dependencies

Author: Sean Bright Date: 2026-05-20

#### chan_websocket: Handle incoming CONTINUATION frames.

Author: George Joseph Date: 2026-05-20

chan_websocket now tells res_http_websocket to accumulate incoming CONTINUATION frames into 1024 byte TEXT or BINARY frames.

Resolves: #1941

#### res_rtp_asterisk: Fix incorrect reference in ast_rtp_get_stat().

Author: George Joseph Date: 2026-05-19

`AST_RTP_STAT_SET(AST_RTP_INSTANCE_STAT_LOCAL_STDEVMES, \ AST_RTP_INSTANCE_STAT_COMBINED_MES, stats->local_stdevmes, \ rtp->rtcp->stdev_rxjitter);`

Should have been

`AST_RTP_STAT_SET(AST_RTP_INSTANCE_STAT_LOCAL_STDEVMES, \ AST_RTP_INSTANCE_STAT_COMBINED_MES, stats->local_stdevmes, \ rtp->rtcp->stdev_rxmes);`

Note the last macro parameter name.

Resolves: #1938

#### jansson: Upgrade version to jansson 2.15.0

Author: Stanislav Abramenkov Date: 2026-05-13

UpgradeNote: jansson has been upgraded to 2.15.0. For more information visit jansson Github page: https://github.com/akheron/jansson/releases/tag/v2.15.0

Resolves: #1931

#### channel.c: Move setting RTP stats from ast_softhangup to ast_ari_channels_hangup.

Author: George Joseph Date: 2026-05-12

The original trigger for setting the RTP stats in ast_softhangup() came from an ARI issue where stats weren't being set in time to be reported on STASIS_END events. The thought was that setting them in a common place like ast_softhangup() would ensure the stats were set in possibly other scenarios. Unfortunately, setting the RTP stats variables in ast_softhangup() broke ABI as it required that no channel locks be held which was not the case earlier.

Given that the original issue was ARI, we can move setting the stats to ast_ari_channels_hangup() in resource_channels just before it calls ast_softhangup(). This might not catch all cases of the stats not being set, but it won't break ABI or deadlock either.

#### res_rtp_asterisk: Add option to control stun host resolution when TTL = 0

Author: George Joseph Date: 2026-05-05

If a hostname is specified for stunaddr in rtp.conf, periodic DNS resolution is enabled based on the TTL returned in the DNS results. If the TTL returned is 0, it means that the next time the IP address is needed, it must be looked up again. I.E. Don't cache. Historically (and incorrectly) however, res_rtp_asterisk stopped the periodic resolution and never re-resolved the hostname again.

Besides what's mentioned in the user notes... * Additional debugging was added in various STUN/DNS functions. * The `rtp show settings` CLI command shows more detailed STUN info. * Some debugging was added to dns_core.c and dns_recurring.c.

UserNote: A new `stunaddr_reresolve_ttl_0` parameter has been added to rtp.conf that allows control over what happens when a STUN server hostname lookup returns a TTL of 0. The values can be set as follows: - 'no': This is the historical (and current default) behavior of not doing any further lookups and continuing to use the last successful result until Asterisk is restarted or rtp.conf is reloaded. - 'yes': Use the last cached result for the current call but trigger re-resolution in the background for the benefit of future calls. If the result of the background lookup is a ttl > 0, periodic resolution will be restarted otherwise the next call will use the new cached value and will trigger a background lookup again.

UserNote: A new CLI command `rtp resolve stun hostname` has been added that will force a resolution of the STUN hostname and (re)start periodic resolution if the result has a TTL > 0.

#### pjsip_configuration: Show actual dtls_verify config.

Author: Jaco Kroon Date: 2026-05-07

Rather than merely showing

dtls_verify : Yes/No

in pjsip show endpoint xxx it will now be shown what exactly is being checked, ie, one of:

dtls_verify : No dtls_verify : Fingerprint dtls_verify : Certificate dtls_verify : Yes

Where Yes implies both Fingerprint and Certificate.

#### app_dial: Properly handle callee hangup while sending digits.

Author: Naveen Albert Date: 2026-05-05

If we are sending digits (either DTMF, MF, or SF) to the called channel after receiving progress or a wink, and the callee hangs up before we have finished sending it digits, there are several problems that can ensue:

- If the callee hung up without answering, the calling channel would hang up and not continue in the dialplan.
- If the callee did answer before hanging up, the answer was never passed through to the caller, since this gets "eaten" by the various digit streaming functions and is never processed by app_dial.

This is generally an edge case that occurs due to some kind of signaling failure, but to better handle this:

- Set to_answer to 0 to prevent hangup on the exit path, just like other parts of wait_for_answer.
- Better document this usage of to_answer.
- If the channel did answer while it was receiving digits, manually answer the calling channel before we abort. The call would not continue in the dialplan anyways (either before or after this fix), but technically the call was answered, so the CDRs should probably reflect that, and this mirrors the behavior of calls which normally do not continue.

Resolves: #1915

UserNote: If a called channel sends progress or wink and the caller begins sending digits but the callee answers and then hangs up before digit sending can finish, the call is now answered before being disconnected. If the callee hangs up without answering, the call now continues in the dialplan.

#### res_pjsip_messaging: Update To URI only if it is a SIP(S) URI

Author: Maximilian Fridrich Date: 2026-05-07

When a message is sent via ARI, the ARI endpoint only provides a To field which is also used as destination field. This means that the To field might not necessarily contain a SIP URI but might instead specify an Asterisk endpoint (in MessageDestinationInfo format). This led to many warnings even though the message was sent correctly.

The fix is to only call `ast_sip_update_to_uri` if the To field starts with the sip: or sips: scheme.

#### manager: Eliminate unnecessary code, simplify sessions in stasis callbacks

Author: Joshua C. Colp Date: 2026-05-04

Due to stasis filtering the stasis callback for AMI type messages is guaranteed to only receive messages that can be turned into AMI events, so remove the check done in the callback.

The sessions container usage for the stasis callbacks has also been simplified by having a reference on the message router subscription instead of having to acquire the sessions from the global object each time.

#### res_stasis/resource_bridges: Split bridge playback control and wrapper cleanup

Author: Peter Krall Date: 2026-04-17

Modified the bridge playback teardown so the worker thread removes only the playback control, while the after-bridge callback removes the playback wrapper once the announcer has actually left the bridge.

This avoids a stale window where a new playback request could create a replacement announcer before the old announcer had fully exited the holding bridge.

Also replaced the flexible trailing bridge_id storage in the shared worker thread data with an optional bridge_id pointer, since recording paths use the same structure without a bridge id.

Fixes: #1861

#### res_pjsip_outbound_publish.c: Add more verbose documentation for outbound_proxy usage

Author: Sebastian Denz Date: 2026-03-26

#### channel.c: Don't lock the channel in ast_softhangup while setting rtp instance vars

Author: George Joseph Date: 2026-05-05

ast_softhangup() was locking the channel before calling ast_rtp_instance_set_stats_vars() which, if the channel was in a bridge, then locked the bridge peer channel. If another thread attempted to set bridge variables on the peer, it would lock that channel first, then this channel causing a lock inversion. ast_softhangup() now holds the channel lock while retrieving the rtp instance, then unlocks it before calling ast_rtp_instance_set_stats_vars(), then locks it again after it returns.

Resolves: #1907

#### chan_pjsip: Fix deadlock when endpoint set_var uses PJSIP_HEADER

Author: Charles Langlois Date: 2026-04-16

When a PJSIP endpoint is configured with set_var invoking a dialplan function (e.g. PJSIP_HEADER(add,...)), chan_pjsip_new() calls pbx_builtin_setvar_helper() while holding the channel lock. For function-style variables, this dispatches to ast_func_write() which, in the case of PJSIP_HEADER, calls ast_sip_push_task_wait_serializer() -- blocking synchronously while the channel lock is held.

If a concurrent operation (ARI, AMI, rtp_check_timeout) traverses the channels container via ast_channel_get_by_name(), it acquires the container lock then tries to lock individual channels in the iteration callback (by_uniqueid_cb/by_name_cb). When the serializer thread also needs the container lock, a circular dependency forms:

    channel_lock -> serializer_wait -> container_lock -> channel_lock

This causes a complete Asterisk freeze. In the observed case, 36 threads were blocked on the container lock until res_freeze_check triggered SIGABRT after its 30-second timeout.

Unlock the channel before iterating endpoint channel_vars so that dialplan functions can block without holding the channel lock. Re-lock the channel for ast_channel_stage_snapshot_done() so the batched snapshot is published under lock and captures the full channel state including the variables set during the loop.

Fixes: #1872

#### res_pjsip: Add per-endpoint RTP port range configuration

Author: mattia Date: 2026-04-01

Add rtp_port_start and rtp_port_end options to PJSIP endpoint configuration, allowing each endpoint to use a dedicated RTP port range instead of the global rtp.conf setting.

This is useful for scenarios where different endpoints need isolated port ranges, such as firewall rules per trunk, multi-tenant systems, or network QoS policies tied to port ranges.

The implementation adds ast_rtp_instance_new_with_port_range() to the RTP engine API, which sets the port range on the instance before the engine allocates the transport. The default RTP engine (res_rtp_asterisk) checks for per-instance overrides in rtp_allocate_transport() and falls back to the global range when none is set.

Both options must be set together, with values >= 1024 and rtp_port_end > rtp_port_start. Setting both to 0 (the default) preserves existing behavior.

Resolves: https://github.com/asterisk/asterisk-feature-requests/issues/71

UserNote: PJSIP endpoints now support rtp_port_start and rtp_port_end options to configure a dedicated RTP port range per endpoint, overriding the global rtp.conf setting.

UpgradeNote: An alembic database migration has been added to add the rtp_port_start and rtp_port_end columns to the ps_endpoints table. Run "alembic upgrade head" to apply the schema change.

DeveloperNote: New public API: ast_rtp_instance_new_with_port_range() creates an RTP instance with a per-instance port range. ast_rtp_instance_get_port_start() and ast_rtp_instance_get_port_end() allow RTP engines to query the override. Third-party RTP engines can use these getters to support per-instance port ranges.

#### app_queue: Fix raise_respect_min lost in copy_rules() breaking rN queue rules

Author: phoneben Date: 2026-04-26

app_queue: Fix raise_respect_min not copied in copy_rules() causing rN rules to be ignored.

`copy_rules()` never copied `raise_respect_min` into the per-call rule list, so the flag was always 0 when a timed penaltychange rule fired, making `rN` behave like plain `N` and raising members below `min_penalty` that should have been excluded.

Also fixes `update_qe_rule()` not propagating the flag from `qe->pr` to `qe`, and dropping the `r` prefix when saving back to `QUEUE_RAISE_PENALTY`.

app_voicemail_odbc: fix msgnum race and crash on failed STORE

Two concurrent callers leaving voicemail to the same mailbox could be assigned the same msgnum because ast_unlock_path() was called before STORE(), allowing a second thread to read the same LAST_MSG_INDEX() before the first INSERT committed. The losing thread got a duplicate key error, but execution continued into notify_new_message() -> RETRIEVE() because the STORE() return value was not checked. RETRIEVE() then fetched the winning thread's DB row, mmap'd its blob size against the locally truncated file, and crashed with SIGBUS.

Hold the path lock through STORE() and bail out on failure.

#### ari_websockets: Fix two issues in the cleanup of outbound websockets.

Author: George Joseph Date: 2026-04-22

1. session_cleanup() now saves the websocket type before unlinking the session from the session registry. This prevents a FRACK when cleaning up per-call websockets when MALLOC_DEBUG is used.

2. session_shutdown_cb() and outbound_sessions_load() now call pthread_cancel() to cancel the session handler thread to prevent the thread from continually trying to connect to a server after the connection config has been removed by a reload. This required the thread to use pthread_cleanup_push() to clean up its reference to the session instead of RAII because RAII destructors don't get run when pthread_cancel() is used.

#### compat.h: Ensure check for `__STDC_VERSION__` is not attempted for c++.

Author: George Joseph Date: 2026-04-27

`__STDC_VERSION__` is specific to C but up until gcc 16, the g++ compiler also defined it. With g++ 16.0 it's no longer defined (which is the correct behavior) so compiling channelstorage_cpp_map_name_id.cc fails. The check for `__STDC_VERSION__` in compat.h is now skipped if we're compiling a C++ source file.

#### pjproject: Backport fix for OpenSSL < 1.1.0 build failure in ssl_sock_ossl.c

Author: phoneben Date: 2026-04-22

Backport pjsip/pjproject#4941 which fixes a build/link failure when compiling against OpenSSL < 1.1.0 (e.g. OpenSSL 1.0.2k on CentOS 7).

Two symbols introduced in OpenSSL 1.1.x were called unconditionally in ssl_sock_ossl.c without version guards:

- `TLS_method()` in `init_ossl_ctx()` is now guarded with `OPENSSL_VERSION_NUMBER < 0x10100000L`, falling back to `SSLv23_method()` on older OpenSSL.

- `SSL_CTX_set_ciphersuites()` is now guarded with `OPENSSL_VERSION_NUMBER >= 0x1010100fL` since this function was introduced in OpenSSL 1.1.1 and is absent in 1.0.x.

Without this fix, linking fails with: undefined reference to `TLS_method' undefined reference to`SSL_CTX_set_ciphersuites'

when building Asterisk with bundled pjproject on systems such as CentOS 7 with OpenSSL 1.0.2k.

Resolves: #1807

#### stasis_broadcast: Add optional ARI broadcast with first-claim-wins

Author: Daniel Donoghue Date: 2026-02-25

Adds two optional modules: res_stasis_broadcast.so: Infrastructure for broadcasting a single incoming channel to multiple ARI applications with atomic first-claim-wins semantics.

app_stasis_broadcast.so: Provides the StasisBroadcast() dialplan application which invokes the broadcast infrastructure.

Both modules are self-contained; if neither is loaded there is zero runtime impact. Loading them does not alter existing Stasis or ARI behavior unless explicitly used.

Key Features (only active when modules are loaded): Fisher-Yates shuffled broadcast dispatch for fair claim races Atomic claim operations using mutex + condition variable signaling Configurable broadcast timeouts Safe regex application filtering with validation to mitigate ReDoS risk Thread-safe channel variable snapshotting (channel locked during reads) Late-claim safety: broadcast context kept alive until after the Stasis session ends so concurrent claimants always receive 409 Conflict rather than 404 Not Found Memory safety via RAII_VAR, ast_json_ref/unref, and ao2 reference counting

Components Added: res/res_stasis_broadcast.c: Core broadcast + claim logic apps/app_stasis_broadcast.c: StasisBroadcast() dialplan application include/asterisk/stasis_app_broadcast.h: Public API header res/ari/resource_events.c: Integrates POST /ari/events/claim endpoint rest-api/api-docs/events.json: New CallBroadcast and CallClaimed events

Implementation Notes: Broadcast contexts reside in an ao2 hash container keyed by channel id. Each context holds atomic claim state, winner application name, timeout metadata, and a condition variable for waiters. Broadcast contexts are kept alive until after stasis_app_exec() returns so that concurrent claimants racing against the timeout always receive 409 Conflict. Broadcast dispatch calls stasis_app_send() directly for each matching application in shuffled order. Regex filters are validated with bounded length, group depth, quantified group count, and alternation limits to reduce pathological backtracking. Timeout calculation uses timespec arithmetic with overflow-safe millisecond remainder handling. Event JSON follows existing Stasis/ARI conventions; references are managed correctly to avoid leaks or double frees.

Optional Nature / Impact: No changes to existing APIs, events, or applications when absent. Clean fallback: systems ignoring the modules behave identically to prior versions.

Development was assisted by Claude (Anthropic). All generated code has been reviewed, tested, and is understood by the author.

UserNote: New optional modules res_stasis_broadcast.so and app_stasis_broadcast.so enable broadcasting an incoming channel to multiple ARI applications. The first application to successfully claim (via POST /ari/events/claim) wins channel control. StasisBroadcast() dialplan application initiates broadcasts. CallBroadcast and CallClaimed events notify applications. When modules are not loaded, behavior is unchanged.

DeveloperNote: New public APIs in stasis_app_broadcast.h: stasis_app_broadcast_channel(), stasis_app_claim_channel(), stasis_app_broadcast_winner(), and stasis_app_broadcast_wait(). New ARI event types (CallBroadcast, CallClaimed) added to events.json. All code is isolated; no existing ABI modified.

#### res_audiosocket: Tolerate non-audio frame types

Author: Sven Kube Date: 2026-04-22

This commit implements the handling of non-voice or DTMF frames like the chan_websocket handling added in #1588. Rather than treating unsupported frames as fatal errors, silently ignore CNG frames and log a warning for other unsupported types.

#### pbx_functions: Save module pointer before calling read and write callbacks.

Author: George Joseph Date: 2026-04-21

Before ast_func_read and ast_func_write call their respective read and write callbacks for registered dialplan functions, they use the module pointer in the registered ast_custom_function structure to increment the module use count. They then decrement the usecount when the callback returns. This prevents the providing module from being unloaded while there's a call using the function.

Some modules, notably func_odbc, create and destroy dialplan functions based on the contents of a config file. Since the ast_custom_function structure is dynamically allocated, it could be destroyed on reload which means when the module's read or write callback returns to the ast_func calls it would try to decrement the usecount using the module pointer from an ast_custom_function structure that has already been freed. Proper locking or reference counting by the module can reduce the possibility of this happening but it can't prevent it because it doesn't have control after its read or write callback has returned to ast_func_read or ast_func_write.

To address this, ast_func_read, ast_func_read2 and ast_func_write save the module pointer to a local variable before calling the module's callback, then use the saved pointer to decrement the use count. The module pointer will always be valid if the module is loaded regardless of the state of the ast_custom_function structure.

#### chan_iax2: Add CHANNEL getter to retrieve auth method.

UserNote: CHANNEL(auth_method) can now be used to retrieve the auth method negotiated for a call on IAX2 channels.

#### fix: backport pjproject stdatomic.h GCC 4.8 build failure patch

#### res_pjsip_maintenance: Add PJSIP endpoint maintenance mode

Author: Daniel Donoghue Date: 2026-03-10

Introduces res_pjsip_maintenance, a loadable module that allows operators to place individual PJSIP endpoints into maintenance mode at runtime without unregistering or disabling them.

While an endpoint is in maintenance mode: * New inbound INVITE and SUBSCRIBE dialogs are rejected with 503 Service Unavailable and a Retry-After: 300 header. * In-progress dialogs (re-INVITE, UPDATE, BYE, etc.) are unaffected and complete normally. * Outbound originations via Dial() or ARI originate are refused before any SIP session is created.

State is held in-memory only and is cleared on module unload or Asterisk restart.

This module was developed with AI assistance (Claude). All code has been reviewed and tested by the author, who takes full responsibility for the submission.

CLI interface: pjsip set maintenance pjsip show maintenance [endpoint]

AMI interface: Action: PJSIPSetMaintenance Endpoint: |all State: on|off

    Action: PJSIPShowMaintenance
    Endpoint: <name>  (optional; omit to list all)

    Emits PJSIPMaintenanceStatus events per result, followed by
    PJSIPMaintenanceStatusComplete. State changes also emit an
    unsolicited PJSIPMaintenanceStatus event.

To support outbound blocking, a new session_create callback is added to ast_sip_session_supplement. Supplements that set this callback are invoked at the start of ast_sip_session_create_outgoing() in res_pjsip_session, before any dialog or invite session resources are allocated. res_pjsip_maintenance registers itself as a session supplement and uses this callback to gate outbound session creation on a per-endpoint basis.

MODULEINFO: pjproject res_pjsip res_pjsip_session

UserNote: New module res_pjsip_maintenance adds runtime maintenance mode for PJSIP endpoints. Use "pjsip set maintenance " to enable or disable, and "pjsip show maintenance" to list affected endpoints. AMI actions PJSIPSetMaintenance and PJSIPShowMaintenance provide programmatic access. No configuration file changes required.

DeveloperNote: ast_sip_session_supplement gains a new optional callback - int (session_create)(struct ast_sip_endpoint endpoint, const char *destination). It is called from the global supplement list (not per-session) at the start of ast_sip_session_create_outgoing() via ast_sip_session_check_supplement_create(). Returning non-zero blocks the outgoing session. Modules that need to gate outbound SIP session creation should register a supplement with this callback set rather than hooking into chan_pjsip directly.

#### chan_iax2: Add another check to abort frame handling if datalen < 0.

#### res_pjsip_outbound_registration: only update the Expires header if the value has changed

Author: Mike Bradeen Date: 2026-04-08

The PJSIP outbound registration API has undocumented behavior when reconfiguring the outbound registration if the expires value being set is the same as what was previously set.

In this case PJSIP will remove the Expires header entirely from subsequent outbound REGISTER requests. To eliminate this as an issue we now check the current expires value against the configured expires value and only apply it if it differs.

This ensures that outbound REGISTER requests always contain an Expires header.

#### build: remove pjsua, pjsystest, Python bindings and asterisk_malloc_debug stubs from pjproject dev build

Author: Alexei Gradinari Date: 2026-04-06

The pjsua Python module and the pjsua/pjsystest apps were used by the Asterisk Test Suite for SIP simulation in dev mode builds. They are now fully obsolete for three independent reasons:

1. pjsua Python bindings officially deprecated upstream. The pjproject maintainers added `pjsip-apps/src/python/DEPRECATED.txt` directing users to the PJSUA2 SWIG binding instead. A build-fix PR (https://github.com/pjsip/pjproject/pull/4892) was closed by the maintainer explicitly citing this deprecation.

2. Removed from the Asterisk Test Suite. As confirmed by @mbradeen: > "We had to get rid of pjsua when we went to Python3 because it would > hang due to a conflict between async calls within pjsua and twisted. > There are still some old references to tests we couldn't fully convert > to sipp, but those are skipped."

3. Broken and unmaintained. Building with Python 2.7 (the only version `configure.ac` searched for) fails with: `_pjsua.c: error: 'INIT_RETURN' undeclared (first use in this function)` due to a bug in pjproject 2.16's `python3_compat.h` that upstream declined to fix.

This PR removes all pjsua-related build artifacts from Asterisk's bundled pjproject build: the pjsua and pjsystest application binaries, the deprecated Python (`_pjsua.so`) bindings, the `asterisk_malloc_debug.c` stubs, and the `PYTHONDEV` detection from `configure.ac`. Also removes `libpjsua` from Asterisk's main linker flags.

DeveloperNote: The pjsua and pjsystest application binaries, the deprecated Python pjsua bindings (`_pjsua.so`), and the `asterisk_malloc_debug.c` stub implementations are no longer built or installed as part of the bundled pjproject dev mode build. The `PYTHONDEV` (python2.7-dev) build dependency is also removed. Developers who relied on the pjsua binary for Test Suite SIP simulation should use SIPp instead, which is the current Asterisk Test Suite standard.

#### callerid: fix signed char causing crash in MDMF parser

Change rawdata buffer from char to unsigned char to prevent sign-extension of TLV length bytes >= 0x80. On signed-char platforms (all Asterisk builds due to -fsigned-char in configure.ac), these values become negative when assigned to int, bypass the `if (res > 32)` bounds check, and reach memcpy as size_t producing a ~18 EB read that immediately crashes with SIGSEGV.

Affects DAHDI analog (FXO) channels only. Not reachable via SIP, PRI/BRI, or DTMF-based Caller ID.
