Lets confirm the following statements now:<div><br></div><div>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.</div>
<div><br></div><div>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).</div>
<div><br></div><div>3. Try using absolute_codec_string before bridging your call to your SIP provider:</div><div><br></div><div><pre style="padding-top:1em;padding-right:1em;padding-bottom:1em;padding-left:1em;border-top-width:1px;border-right-width:1px;border-bottom-width:1px;border-left-width:1px;border-top-style:dashed;border-right-style:dashed;border-bottom-style:dashed;border-left-style:dashed;border-top-color:rgb(47,111,171);border-right-color:rgb(47,111,171);border-bottom-color:rgb(47,111,171);border-left-color:rgb(47,111,171);background-color:rgb(255,255,255);line-height:1.1em">
&lt;action application=&quot;set&quot; data=&quot;absolute_codec_string=GSM&quot;/&gt;
&lt;action application=&quot;bridge&quot; data=&quot;sofia/gateway/your_provider/12345678901_example&quot;/&gt;</pre></div><div><br></div><div>And reply back if this changes anything...</div><div><br></div><div>Vitalie</div>

&gt; Understood your point about G722. But if my list has GSM at higher priority<br>
&gt; over PCMU/PCMA and far-end SDP supports GSM then why isn&#39;t the call using<br>
&gt; GSM?<br>
&gt;<br>
&gt; I don&#39;t know where G726 comparisons are coming from. If I haven&#39;t mentioned<br>
&gt; it in vars.xml and far-end SDP doesn&#39;t support it then why would it even<br>
&gt; consider that codec?<br>
