I have an iSAC client that I&#39;m testing against FreeSwitch.<div><br></div><div>Currently I have my vars.xml with:</div><div><br></div><div>global_codec_prefs=isac,PCMU,PCMA,GSM,G722</div><div><br></div><div>Which works, but only if the client specifies 32kHz mode. I want to test 16kHz mode, but FreeSwitch returns &#39;not acceptable here&#39;, and I can see that when Freeswitch offers iSAC in the SDP it says only isac/32000.</div>
<div><br></div><div>So how to enable 16kHz mode for isac?</div><div><br></div><div>I tried explicitly putting isac@320000h30i, isac@16000h30i into vars.xml, but this simply stops FreeSwitch from accepting anything.</div><div>
<br></div><div>Hints gladly received.</div><div><br></div><div>Regards,</div><div>Martyn</div><div><br></div><div><br></div><div><br></div><div><br></div><div><br></div>
