89001d3156 res_pjsip_authenticator_digest: Fix SEGV if get_authorization_hdr returns NULL.
In the highly-unlikely event that get_authorization_hdr() couldn't find an
Authorization header in a request, trying to get the digest algorithm
would cauase a SEGV.  We now check that we have an auth header that matches
the realm before trying to get the algorithm from it.

82f5a45a9e sorcery: Prevent duplicate objects and ensure missing objects are created on update
This patch resolves two issues in Sorcery objectset handling with multiple
backends:

1. Prevent duplicate objects:
   When an object exists in more than one backend (e.g., a contact in both
   'astdb' and 'realtime'), the objectset previously returned multiple instances
   of the same logical object. This caused logic failures in components like the
   PJSIP registrar, where duplicate contact entries led to overcounting and
   incorrect deletions, when max_contacts=1 and remove_existing=yes.

   This patch ensures only one instance of an object with a given key is added
   to the objectset, avoiding these duplicate-related side effects.

2. Ensure missing objects are created:
   When using multiple writable backends, a temporary backend failure can lead
   to objects missing permanently from that backend.
   Currently, .update() silently fails if the object is not present,
   and no .create() is attempted.
   This results in inconsistent state across backends (e.g. astdb vs. realtime).

   This patch introduces a new global option in sorcery.conf:
     [general]
     update_or_create_on_update_miss = yes|no

   Default: no (preserves existing behavior).

   When enabled: if .update() fails with no data found, .create() is attempted
   in that backend. This ensures that objects missing due to temporary backend
   outages are re-synchronized once the backend is available again.

   Added a new CLI command:
     sorcery show settings
   Displays global Sorcery settings, including the current value of
   update_or_create_on_update_miss.

   Updated tests to validate both flag enabled/disabled behavior.

Fixes: #1289

UserNote: Users relying on Sorcery multiple writable backends configurations
(e.g., astdb + realtime) may now enable update_or_create_on_update_miss = yes
in sorcery.conf to ensure missing objects are recreated after temporary backend
failures. Default behavior remains unchanged unless explicitly enabled.

7e68659616 chan_dahdi: Fix erroneously persistent dialmode.
It is possible to modify the dialmode setting in the chan_dahdi/sig_analog
private using the CHANNEL function, to modify it during calls. However,
it was not being reset between calls, meaning that if, for example, tone
dialing was disabled, it would never work again unless explicitly enabled.

This fixes the setting by pairing it with a "perm" version of the setting,
as a few other features have, so that it can be reset to the permanent
setting between calls. The documentation is also clarified to explain
the interaction of this setting and the digitdetect setting more clearly.

d4d7f2e6e4 chan_websocket: Allow additional URI parameters to be added to the outgoing URI.
* Added a new option to the WebSocket dial string to capture the additional
  URI parameters.
* Added a new API ast_uri_verify_encoded() that verifies that a string
  either doesn't need URI encoding or that it has already been encoded.
* Added a new API ast_websocket_client_add_uri_params() to add the params
  to the client websocket session.
* Added XML documentation that will show up with `core show application Dial`
  that shows how to use it.

Resolves: #1352

UserNote: A new WebSocket channel driver option `v` has been added to the
Dial application that allows you to specify additional URI parameters on
outgoing connections. Run `core show application Dial` from the Asterisk CLI
to see how to use it.

72d1b469fd chan_websocket: Fix buffer overrun when processing TEXT websocket frames.
ast_websocket_read() receives data into a fixed 64K buffer then continually
reallocates a final buffer that, after all continuation frames have been
received, is the exact length of the data received and returns that to the
caller.  process_text_message() in chan_websocket was attempting to set a
NULL terminator on the received payload assuming the payload buffer it
received was the large 64K buffer.  The assumption was incorrect so when it
tried to set a NULL terminator on the payload, it could, depending on the
state of the heap at the time, cause heap corruption.

process_text_message() now allocates its own payload_len + 1 sized buffer,
copies the payload received from ast_websocket_read() into it then NULL
terminates it prevent the possibility of the overrun and corruption.

8bfa3be27f dsp.c: Improve debug logging in tone_detect().
The debug logging during DSP processing has always been kind
of overwhelming and annoying to troubleshoot. Simplify and
improve the logging in a few ways to aid DSP debugging:

* If we had a DSP hit, don't also emit the previous debug message that
  was always logged. It is duplicated by the hit message, so this can
  reduce the number of debug messages during detection by 50%.
* Include the hit count and required number of hits in the message so
  on partial detections can be more easily troubleshot.
* Use debug level 9 for hits instead of 10, so we can focus on hits
  without all the noise from the per-frame debug message.
* 1-index the hit count in the debug messages. On the first hit, it
  currently logs '0', just as when we are not detecting anything,
  which can be confusing.

95d65bbe30 xmldoc.c: Fix rendering of CLI output.
If you do a `core show application Dial`, you'll see it's kind of a mess.
Indents are wrong is some places, examples are printed in black which makes
them invisible on most terminals, and the lack of line breaks in some cases
makes it hard to follow.

* Fixed the rendering of examples so they are indented properly and changed
the color so they can be seen.
* There is now a line break before each option.
* Options are now printed on their own line with all option content indented
below them.

Example from Dial before fixes:
```
    Example: Dial 555-1212 on first available channel in group 1, searching
    from highest to lowest

    Example: Ringing FXS channel 4 with ring cadence 2

    Example: Dial 555-1212 on channel 3 and require answer confirmation

...

    O([mode]):
        mode - With <mode> either not specified or set to '1', the originator
        hanging up will cause the phone to ring back immediately.
 - With <mode> set to '2', when the operator flashes the trunk, it will ring
 their phone back.
Enables *operator services* mode.  This option only works when bridging a DAHDI
channel to another DAHDI channel only. If specified on non-DAHDI interfaces, it
will be ignored. When the destination answers (presumably an operator services
station), the originator no longer has control of their line. They may hang up,
but the switch will not release their line until the destination party (the
operator) hangs up.

    p: This option enables screening mode. This is basically Privacy mode
    without memory.
```

After:
```
    Example: Dial 555-1212 on first available channel in group 1, searching
    from highest to lowest

     same => n,Dial(DAHDI/g1/5551212)

    Example: Ringing FXS channel 4 with ring cadence 2

     same => n,Dial(DAHDI/4r2)

    Example: Dial 555-1212 on channel 3 and require answer confirmation

     same => n,Dial(DAHDI/3c/5551212)

...

    O([mode]):
        mode - With <mode> either not specified or set to '1', the originator
        hanging up will cause the phone to ring back immediately.
        With <mode> set to '2', when the operator flashes the trunk, it will
        ring their phone back.
        Enables *operator services* mode.  This option only works when bridging

        release their line until the destination party (the operator) hangs up.

    p:
        This option enables screening mode. This is basically Privacy mode

```

There are still things we can do to make this more readable but this is a
start.

9bfd4c2994 pbx_lua.c: segfault when pass null data to term_color function

pbx_lua.c will try to get data for this playback using lua_tostring function.

Then, it calls term_color with NULL data.
term_color function can call(if we don't use vt100 compat term)
ast_copy_string with NULL inbuf which cause segfault. bt example:

15f93f8cfa app_dial.c: Moved channel lock to prevent deadlock
It's reproducible with pbx_lua, not regular dialplan.

deadlock description:
1. asterisk locks a channel
2. calls function onedigit_goto
3. calls ast_goto_if_exists funciton
4. checks ast_exists_extension -> pbx_extension_helper
5. pbx_extension_helper calls pbx_find_extension
6. Then asterisk starts autoservice in a new thread
7. autoservice run tries to lock the channel again

Because our channel is locked already, autoservice can't lock.
Autoservice can't lock -> autoservice stop is waiting forever.
onedigit_goto waits for autoservice stop.

e50d0cf741 channelstorage_cpp_map_name_id.cc: Refactor iterators for thread-safety.
The fact that deleting an object from a map invalidates any iterator
that happens to currently point to that object was overlooked in the initial
implementation.  Unfortunately, there's no way to detect that an iterator
has been invalidated so the result was an occasional SEGV triggered by modules
like app_chanspy that opens an iterator and can keep it open for a long period
of time.  The new implementation doesn't keep the underlying C++ iterator
open across calls to ast_channel_iterator_next() and uses a read lock
on the map to ensure that, even for the few microseconds we use the
iterator, another thread can't delete a channel from under it.  Even with
this change, the iterators are still WAY faster than the ao2_legacy
storage driver.

Full details about the new implementation are located in the comments for
iterator_next() in channelstorage_cpp_map_name_id.cc.

DeveloperNote: The 32-bit ast_options has no room left to accomodate new

references to ast_options have been updated to use the 64-bit flag
manipulation macros.  External module references to the 32-bit ast_options
should continue to work on little-endian systems because the
least-significant bytes of a 64 bit integer will be in the same location as a
32-bit integer.  Because that's not the case on big-endian systems, we've
swapped the bytes in the flags manupulation macros on big-endian systems
so external modules should still work however you are encouraged to test.

df7fa2d1fd res_config_odbc: Prevent Realtime fallback on record-not-found (SQL_NO_DATA)
This patch fixes an issue in the ODBC Realtime engine where Asterisk incorrectly
falls back to the next configured backend when the current one returns
SQL_NO_DATA (i.e., no record found).
This is a logical error and performance risk in multi-backend configurations.

Solution:
Introduced CONFIG_RT_NOT_FOUND ((void *)-1) as a special return marker.
ODBC Realtime backend now return CONFIG_RT_NOT_FOUND when no data is found.
Core engine stops iterating on this marker, avoiding unnecessary fallback.

Other Realtime backends (PostgreSQL, LDAP, etc.) can be updated similarly.

9bef59f44d chan_pjsip.c: Change SSRC after media source change
When the RTP media source changes, such as after a blind transfer, the new source introduces a discontinuous timestamp. According to RFC 3550, Section 5.1, an RTP stream's timestamp for a given SSRC must increment monotonically and linearly.
To comply with the standard and avoid a large timestamp jump on the existing SSRC, a new SSRC is generated for the new media stream.
This change resolves known interoperability issues with certain SBCs (like Sonus/Ribbon) that stop forwarding media when they detect such a timestamp violation. This code uses the existing implementation from chan_sip.

aa14410651 Media over Websocket Channel Driver
* Created chan_websocket which can exchange media over both inbound and
outbound websockets which the driver will frame and time.
See http://s.asterisk.net/mow for more information.

* res_http_websocket: Made defines for max message size public and converted
a few nuisance verbose messages to debugs.

* main/channel.c: Changed an obsolete nuisance error to a debug.

* ARI channels: Updated externalMedia to include chan_websocket as a supported
transport.

UserNote: A new channel driver "chan_websocket" is now available. It can
exchange media over both inbound and outbound websockets and will both frame
and re-time the media it receives.
See http://s.asterisk.net/mow for more information.

UserNote: The ARI channels/externalMedia API now includes support for the
WebSocket transport provided by chan_websocket.

838541d767 channelstorage: Rename callbacks that conflict with DEBUG_FD_LEAKS.
DEBUG_FD_LEAKS replaces calls to "open" and "close" with functions that keep
track of file descriptors, even when those calls are actually callbacks
defined in structures like ast_channelstorage_instance->open and don't touch
file descriptors.  This causes compilation failures.  Those callbacks
have been renamed to "open_instance" and "close_instance" respectively.

46d340c424 audiohook.c: Improve frame pairing logic to avoid MixMonitor breakage with mixed codecs
This patch adjusts the read/write synchronization logic in audiohook_read_frame_both()
to better handle calls where participants use different codecs or sample sizes
(e.g., alaw vs G.722). The previous hard threshold of 2 * samples caused MixMonitor
recordings to break or stutter when frames were not aligned between both directions.

The new logic uses a more tolerant limit (1.5 * samples), which prevents audio tearing
without causing excessive buffer overruns. This fix specifically addresses issues
with MixMonitor when recording directly on a channel in a bridge using mixed codecs.

e63d87a064 utils.h: Add rounding to float conversion to int.
Quote from an audio engineer NR9V:
There is a minor issue of a small amount of crossover distortion though as a result of `ast_slinear_saturated_multiply_float()` not rounding the float. This could result in some quiet but potentially audible distortion artifacts in lower volume parts of the signal. If you have for example a sign wave function with a max amplitude of just a few samples, all samples between -1 and 1 will be truncated to zero, resulting in the waveform no longer being a sine wave and in harmonic distortion.
