[OpenSIPS-Users] Problem with OpenSIPS 1.7, NAT and RTPProxy

Thanks, that really helped.

I am still having problem with the following: when user x calls user y,
audio is one-way, and when audio y calls x, audio is two-way. Why is it so?
What could be the possible reasons?

Also would like to add that -- iptables has to be appropriate rules on
opensips to get clients connecting to it or even rtpproxy connecting to it.
