[Freeswitch-users] Configuring different codecs for internal and external calls.

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.
