[OpenSIPS-Users] Inconsistent c= and o= using rtpproxy_offer and rtpproxy_answer

[Nick Cameo]

Hello Bogdan,

Put the instance in debug level 4, inserted xlog in the on_reply as seen in the
first line. Basically no error has been raised however, the SDP payload
was not modified as was suggested by force_rtp_proxy:
