Hello,
I'm using the function sdp_remove_codecs_by_id from sdpops module in order
to remove some codecs in INVITE request before send it to freeswitch, but
the function doesn't remove the codec, and it doesn't give any error
message.
I'm using this function in request route.
Kamailio version is 4.2.2.
INVITE that kamailio receives from phone:
