lvl commented on ASTERISK-27774:
--------------------------------

I just tested it on Asterisk 15.3.0, the behavior is the same with a musiconhold class defined in musiconhold.conf

FYI, the verbose log:

{code}
    -- Stopped music on hold on PJSIP/proxy-00000000
    -- Playing periodic announcement
    -- <PJSIP/proxy-00000000> Playing '/var/prompts/announcement.slin16' (language 'nl')
    -- Started music on hold, class 'blah', on channel 'PJSIP/proxy-00000000'
    -- Stopped music on hold on PJSIP/proxy-00000000
    -- Playing periodic announcement
    -- <PJSIP/proxy-00000000> Playing '/var/prompts/announcement.slin16' (language 'nl')
    -- Started music on hold, class 'blah', on channel 'PJSIP/proxy-00000000'
    -- Stopped music on hold on PJSIP/proxy-00000000
    -- Playing periodic announcement
    -- <PJSIP/proxy-00000000> Playing '/var/prompts/announcement.slin16' (language 'nl')
    -- Started music on hold, class 'blah', on channel 'PJSIP/proxy-00000000'
{code}

The musiconhold starts from the beginning of the file after each "Started music on hold" log line.

> The fix for ASTERISK-24329 is causing a regression during "regular" music on hold behavior.
> Imagine a simple musiconhold setup, configured via realtime.

> {code}
> In /ext/moh/82497 are one or more audio files with a length of around 3 minutes. If a queue is configured with a periodic announcement every 30 seconds, the following will occur:
> * Caller hears music on hold file #1, playing from the beginning
> * After 30 seconds, the caller will hear the announcement
> * Caller hears music on hold file #1, playing from the beginning
> * After 30 seconds, the caller will hear the announcement
> * ...
> E.g., if the periodic announcement is made every 30 seconds the caller will only ever hear the first 30 seconds of music on hold over and over again.
> I don't fully understand the issue reported in ASTERISK-24329, but if this new behavior is indeed desirable in some cases I think it should be made configurable with the default behavior reverted back to how it was in 15.2.
