[Freeswitch-users] External voicemail issue

[Elliot Farmer]

I've done some further testing and the issue appears to be isolated to the
voicemail system.

To test I configured the inbound dialplan to play two wav files before
transferring the call...

1) 8kz wav from wikipedia http://www.nch.com.au/acm/8kulaw.wav
2)
/usr/local/freeswitch/sounds/en/us/callie/ivr/48000/ivr-you_are_number_one.wav

Both play fine, as soon as the call is transferred to voicemail (via
extension 1000 that is not registered at the time) the quality drops and I
start loosing speech. I've tried preferring the PCMU codec within vars but
I seem to have a lot of "TRANSCODING_NECESSARY" messages, they are not
isolated to the voicemail steps however.

Has anyone got an idea where I can start to look? Any help would be much
appreciated.
