Hi all, Can I ask 2 questions about codec negotiation: 1. Is it possible Freeswitch to work negotiate codecs between two phones as it is described below. INVITE from A with some codecs in SDP ---> Freeswitch rewrites codec preference according absolute_codec_string but exclude all codecs not offered by A ----> INVITE to B with rewrited SDP. example: from A SDP:PCMA,PCMU,SPEEX ----> absolute_codec_string=G722,PCMU,PCMA,GSM ----> to B SDP: PCMU,PCMA 2. Can I get codec list in INVITE with mod_perl for example or via xml_curl without processing SDP variable (switch_r_sdp). It will be useful to be in format that absolute_codec_string variable takes. Thanks
