Problems with Codec, and setup. No wholesalers work.

Hello,

Weve setup our service and asterisk is working great. DIDs work great and calls can go through. The issue is with wholesalers. Most require a g729 and asterisk only comes with g711. Therfore for testing weve purchased 1 G729 Codec from Digium.

We set the codec up just like it was explained and tried to test a call, here is a example calling card SIP settings:

Code:

[91785]
accountcode=NUMBER
regexten=NUMBER
amaflags=billing
context=a2billing
dtmfmode=RFC2833
host=dynamic
nat=yes
qualify=no
secret=PASSWORD
type=friend
username=NUMER
disallow=all
allow=ulaw
allow=g729
regseconds=0
cancallforward=yes

as you can see we have g729 and Ulaw enabled with the proper codecs in place. We trace the calls out to the providers who said they allow g723 and g729, so we should be fine. When traced, our call goes through on ULAW and the receive it on ULAW|h.

We never get connected to our destination country which is Bangladesh. It never connects for some reason. Even when we have G729, ULAW is being used. And the provider said they give g729 but still not luck. This is not just with one provider but every sigple one that we have tried. WEve tried total of 7 services.

Please advise on what can we do to fix this.
Thanks

Try switching the placement of g729 and ulaw around. It's in order of preference.

ie:

change

Code:

disallow=all
allow=ulaw
allow=g729

to...

Code:

disallow=all
allow=g729
allow=ulaw

Please let us know if it works!
