[OpenSIPS-Users] can't force rtpproxy use a new IP in SDP

Hi, Matt!

The fix was only reported by Ovidiu and I was the one that fixed it in 
OpenSIPS's revision 8616 on trunk and 8639 on 1.7.1. This doesn't have 
anything to do with Kamailio. Can you please check if you have these 
changes? Because otherwise I don't think it will work.

Regards,
Ra(zvan
