                 Key: ASTERISK-25428
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-25428
             Project: Asterisk
          Issue Type: Bug

    Affects Versions: 11.19.0
         Environment: ubuntu precise and trusty
            Reporter: Peter Katzmann


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.
