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
