[Freeswitch-users] Using H264 with Verto

[Magnus Kelly]

Well the issue I have is I trying to remove H.264 from the codecs listed in
the SDP,  as although its not listed in the codec section of vars.xml at
all, enabling mod_av appears to mean that by default H.264 is added in the
SDP for each outbound SIP invite, resulting in calls to PSTN SIP G/W
failing with unacceptable codec. Advice on how to prevent or make selective
per SIP profile most welcome.
Thanks
Magnus
