Lets confirm the following statements now: 1.You need OUTGOING leg to use GSM codec, right? (You wont be able to use G729 right now as it needs the license). By OUTGOING I mean call from FreeSWITCH to your provider, and not back. 2. If #1 is true, then inbound-codec-negotiation is not much useful at this point. Because this setting is for INCOMING leg, and not for OUTGOING. And even if it _might_ be using GSM for INCOMING leg, but still transcode to the OUTGOING PCMA/PCMU by some reason (this is what we need to find out - why). 3. Try using absolute_codec_string before bridging your call to your SIP provider: <action application="set" data="absolute_codec_string=GSM"/> <action application="bridge" data="sofia/gateway/your_provider/12345678901_example"/> And reply back if this changes anything...

Under my sipinterface_1 profile that I use for these calls, I have:
<param name="inbound-codec-negotiation" value="greedy"/>

Understood your point about G722. But if my list has GSM at higher priority over PCMU/PCMA and far-end SDP supports GSM then why isn't the call using GSM?
I don't know where G726 comparisons are coming from. If I haven't mentioned it in vars.xml and far-end SDP doesn't support it then why would it even consider that codec?
From: wiki.freeswitch.org/wiki/Sofia_Configuration_Files (inbound-codec-negotiation): 'generous' permits the remote codec list have precedence and 'win' the codec negotiation and selection process
