Two asterisk boxes 150 miles apart, both cvs-head as of this morning
(and since Sept 27th), connected via iax2 with low-utilized ds3 internet,
C7960 calls exten on remote system (also C7960), and call goes to VM.
No other calls in either system (eg, no load).

Both boxes have iax config'ed as:
trunk=yes
allow=ilbc
jitterbuffer=yes
Recorded VM messages are very distorted.

Changing only jitterbuffer=no (and * restart), recorded VM messages are
very clean. With jitterbuffer=yes and trunk=no, messages are very clean.

Both boxes config'ed as:
trunk=yes
allow=gsm
jitterbuffer=yes
Recorded VM messages are very clean.

Conclusion: looks like the combination of trunk=yes and jitterbuffer=yes
with ilbc is causing the distorted VM messages. Normal answered calls
have no distortion.

Is this an unacceptable iax config or does this represent a bug?
(Problem can be recreated at will and is very consistent.)


Try using trunktimestamps as well..
