3cx soft phone gsm and g729a codec add - because it`s very need and in the free version it is no work. So....

1. GSM codec is present in 3CX Phone.
2. G729 is commercial codec (patented), so it cannot be added to free softphone.

Are you willing to pay for the g729a codec?

[vpaulo]

I pay for system 3cx. And in the pay version this codec are present. May be you can simply export it to freeversion of 3cx phone? and simply import codec from server )

I agree with vpaulo, I feel there should be an accompanying licensed version of 3cxphone when purchasing 3cx PBX.
