[asterisk-bugs] [JIRA] (ASTERISK-26094) stasis: Playing MOH to bridge with ARI does not work

    [ https://issues.asterisk.org/jira/browse/ASTERISK-26094?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=231689#comment-231689 ] 

Cameron commented on ASTERISK-26094:
------------------------------------

This really appears to be nearly the same issue as ASTERISK-26083. Can what was done for the announcer channels be done to the moh channels?

I added some debug code, and found out that the ao2_find(app_bridges_moh... [1] returns a moh_wrapper even after the bridge has been destroyed and recreated. That leads to ast_channel_get_by_name and the function returning NULL [2]. I would expect the moh_wrapper to be destroyed when the bridge is destroyed.

> I do the following on an incoming call:
> 1 - Create/Update a bridge using ARI (POST to /bridges/{bridgeid} with custom bridgeid and type=mixing
> 2 - Add current channel to bridge (POST /bridges/{bridgeId}/addChannel). Nothing for role. There is now 1 channel in bridge.
>     -- Channel PJSIP/abc-00000000 joined 'simple_bridge' stasis-bridge <1111a>
> 3 - Play moh (POST to /bridges/{bridgeid}/moh).
> Expected to hear something on channel, but nothing. Console debug says moh started and then immediately says it stopped with no reason why.
>     -- Channel Announcer/ARI_MOH-00000000;2 joined 'simple_bridge' stasis-bridge <1111a>
>     -- Started music on hold, class 'en', on channel 'Announcer/ARI_MOH-00000000;1'
>     -- Stopped music on hold on Announcer/ARI_MOH-00000000;1
> 4 - Play moh again. Same parameters.
> Now moh file plays just fine. The single short wav file plays over and over as expected.
> 5 - Hangup channel, and repeat.
> After the steps above, every time I POST to /bridges/{bridgeid}/moh I get an error back "Allocation failed". Nothing is heard. Nothing is logged on asterisk console for this POST. (Debug 9, verbose 9)
