Peter Katzmann commented on ASTERISK-25428:
-------------------------------------------
The call to record fails if the allowed codecs are only speex/silk.
The call to record is ok if ulaw/alaw or g722 is allowed
But it fails only when the call is routed back to origin server (in this case from 7000/ServerA over 8000/ServerB to Record/ServerA)
When we change the scenario for eg. to
7000/ServerA over 8000/ServerB to Record/ServerB
or
7000/ServerA over 7000/ServerB to Record/Server C
it works.

> There are two Servers (A and B) connected over wan via silk and speex
> There is user 7000 on Server A and user 8000 on Server B.
> Voicemail will only be handled from server A.
> User 8000 has forwarding to voicemail after 5 Seks.
> Now User 7000 calls user 8000, when User 8000 picks up teh phone everything is OK.
> If the call is expired it will be forwarded to the voicemail server A, in this case the call fails with no acceptable codec offer.
> When i modify the sip conf for server A or Server B to alow ulaw/alaw or g722 voicemail works as expected.
