the entire sdp is available as a variable (route the call to the info app to see the variables) <br>so if you have inbound-late-negotiation set to true on the sip profile<br>then you can use a regex or a script to set absolute_codec string before you answer.<br>

Hi all,<br><br>Can I ask 2 questions about codec negotiation:<br><br>1. Is it possible Freeswitch to work negotiate codecs between two phones as it is described below.<br>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.<br>
<br>example:<br>from A SDP:PCMA,PCMU,SPEEX ----> absolute_codec_string=G722,<div>PCMU,PCMA,GSM ----> to B SDP: PCMU,PCMA<br><br>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.<br>
<br>Thanks</div>
