Hello,

How would I configure global_codec_prefs and outbound_codec_prefs for the following:

All calls between freeswitch extensions GSM.

All calls going out from an extension on Freeswitch using GSM (between the endpoint and freeswitch) and then out to a SIP gateway using PCMA or PCMU.

Calls coming in from another SIP gateway to freeswitch using PCMU or PCMA and then transcoded to a local extension using GSM.

Is this it?

<X-PRE-PROCESS cmd="set" data="global_codec_prefs=GSM"/>

<X-PRE-PROCESS cmd="set" data="outbound_codec_prefs=PCMU,PCMA"/>

Thanks,

Maxim.
