6. Your problem:

I have configured a SIP trunk, my problem is that the sip trunk provider tells me that only works with GSM codec and I have the plant set to work with G729 codec. but the packets are large supplier says is why I have problems with choppy calls heard. provider says I'm eating the 400K channel 3 or 4 calls.

Perform a traffic analysis and I find that I'm used G729.

With Brekeke I can configure to use the GSM codec.

Thanks.

h1, you tried set Codec priority 8,0 - ??? sometimes helps
Options > Settings -> PBX system settings -> Codec priority 8,0
Options > Settings -> Media Server system settings -> Codec priority 8,0

and in ARS

or 18,0 but I have not tested

For your info..

You can check codec's Payload Type number at

For example
G729 is 18
GSM is 3
