[OpenSIPS-Users] rtpproxy_answer issue

I am going to try and replace rtpproxy_offer/rtpproxy_answer with 

I have compared 183/200 messages on calls that have failed against calls 
that are good, and the only difference is that it doesn't correctly 
rewrite the SDP IP addresses (which is what I would expect since the 
call to rtpproxy_answer failed).

I think the next thing to do is to turn on rtpproxy debug logs, but I 
was trying to avoid this since it is a production environment and I 
can't seem to replicate the issue in my development environment.

Thanks a lot for your help, I truly appreciate your time!
