Trans-coding issues in case of G729 or G723 can be handled as: http://wiki.freeswitch.org/wiki/Sofia#sip_renegotiate_codec_on_reinvite See http://wiki.freeswitch.org/wiki/Channel_Variables#Codec_Related for codec related variables. Also, there is a configuration in internal and external profiles to define a list of codec in each profile which can be set in global configurationhttp://wiki.freeswitch.org/wiki/Config_external.xml <param name="codec-prefs" value="$${outbound_codec_prefs}"/> you can see SIP dialogues on each phone IP to verify which codec are being offered ngrep -q -Wbyline '' port 5060 and host x.x.x.x Regards, Zohair Raza On Thu, Dec 22, 2011 at 2:54 AM, Nandy Dagondon <gcd@i.ph> wrote: it's found here: http://wiki.freeswitch.org/wiki/Codec_negotiation hope this answers your question.
