[SR-Users] Function sdp_remove_codecs_by_id seems to be not working

[Dragos Oancea]

Hi
Did you use msg_apply_changes() before relaying the INVITE ?http://kamailio.org/docs/modules/4.1.x/modules/textopsx.html#textopsx.f.msg_apply_changes

 Subject: [SR-Users] Function sdp_remove_codecs_by_id seems to be not working
   
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:
