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:
