Trying to figure out why my codec rules are being ignored. I'd like to
utilize g726 on my inter server IAX2 trunks.
Scenario:
Polycom 501 g729, ulaw enabled
|
\/
Astersik Server 1
- polycom extension: allow=ulaw dissallow=all
- trunk to peer : allow=g726, dissallow=all
|
\/
Asterisk Server 2
- trunk - user settting for server 1: allow=g726, dissallow=all
- trunk - peer 'LDprovider' : allow=g726, dissallow=none
|
\/
LD Provider
When the polycom dials outbound that goes to the LD Provider, it fails
and says call could not be bridged. If I alter peer-trunk to the LD
provider to allow=g726&ulaw, the call goes through but as ulaw all the way.
show translation gives:

Any ideas to what is stopping the transcoding on the trunk?
