When enabled cause addition of UNPAUSE event on every re-PAUSE with reason changed. - #### pbx\_builtins: Allow custom tone for WaitExten. The tone used while waiting for digits in WaitExten can now be overridden by specifying an argument for the ‘d’ option. - #### res\_tonedetect: Add option for TONE\_DETECT detection to auto stop. The ‘e’ option for TONE\_DETECT now allows detection to be disabled automatically once the desired number of matches have been fulfilled, which can help prevent race conditions in the dialplan, since TONE\_DETECT does not need to be disabled after a hit. - #### sorcery: Prevent duplicate objects and ensure missing objects are created on u.. 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. - #### chan\_websocket: Allow additional URI parameters to be added to the outgoing URI. 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. - #### app\_chanspy: Add option to not automatically answer channel. ChanSpy and ExtenSpy can now be configured to not automatically answer the channel by using the ‘N’ option. - #### cel: Add STREAM\_BEGIN, STREAM\_END and DTMF event types. Enabling the tracking of the STREAM\_BEGIN and the STREAM\_END event types in cel.conf will log media files and music on hold played to each channel. The STREAM\_BEGIN event’s extra field will contain a JSON with the file details (path, format and language), or the class name, in case of music on hold is played. The DTMF event’s extra field will contain a JSON with the digit and the duration in milliseconds. - #### res\_srtp: Add menuselect options to enable AES\_192, AES\_256 and AES\_GCM Options are now available in the menuselect “Resource Modules” category that allow you to enable the AES\_192, AES\_256 and AES\_GCM cipher suites in res\_srtp. Of course, libsrtp and OpenSSL must support them but modern versions do. Previously, the only way to enable them was to set the CFLAGS environment variable when running ./configure. The default setting is to disable them preserving existing behavior. - #### cdr: add CANCEL dispostion in CDR A new CDR option “canceldispositionenabled” has been added that when set to true, the NO ANSWER disposition will be split into two dispositions: CANCEL and NO ANSWER. The default value is ‘no’ - #### func\_curl: Allow auth methods to be set. The httpauth field in CURLOPT now allows the authentication methods to be set. - #### Media over Websocket Channel Driver 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](http://s.asterisk.net/mow) for more information. The ARI channels/externalMedia API now includes support for the ### Upgrade Notes: ### Developer Notes: - #### ARI: Add command to indicate progress to a channel A new ARI endpoint is available at `/channels/{channelId}/progress` to indicate progress to a channel. - #### options: Change ast\_options from ast\_flags to ast\_flags64. The 32-bit ast\_options has no room left to accomodate new options and so has been converted to an ast\_flags64 structure. All internal 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. ### Commit Authors: - Alexei Gradinari: (2) - Alexey Khabulyak: (2) - Allan Nathanson: (1) - Artem Umerov: (1) - Ben Ford: (1) - George Joseph: (12) - Igor Goncharovsky: (2) - Jaco Kroon: (1) - Joe Garlick: (1) - Jose Lopes: (1) - Kodokaii: (1) - Martin Tomec: (1) - Mike Bradeen: (1) - Mkmer: (1) - Naveen Albert: (15) - Sean Bright: (2) - Sperl Viktor: (2) - Stanislav Abramenkov: (1) - Stuart Henderson: (1) - Sven Kube: (2) - Tinet-Mucw: (2) - Zhou\_jiajian: (1) ---
