#### Description There's a small regression after #2497.
If SDP didn't have an "a=rtcp" header (RFC1889 behavior), Kamailio had thrown an Error `can't extract 'a=rtcp' IP from the SDP` on every INVITE. After the PR Kamailio does not flood into log.
Also refactored #2769. You can view, comment on, or merge this pull request online at:
