[OpenSIPS-Users] opensips vs rtpproxy

[nick at uni-petrol.com]

Dear All!

OS: CentOS 5.6 x86_64
OpenSIPS: trunk 7904 revision
RTP Rroxy: latest from git

I have strange errors and garbage in RTP Proxy when parsing information 
coming from OpenSIPS and calling from 2000 at y.y.y.y to 1000 at y.y.y.y 
through OpenSIPS+RTP Rroxy.
RTP Rroxy are on different server then OpenSIPS and they connect each 
other through LAN and WAN.
On LAN they exchange technical information (RTP sock, RTP timeout 
notify socket) and through WAN they exchange information (SIP & RTP) 
with SIP clients (UAC & UAS).

Both phones (1000 & 2000) are on the same LAN and go through same NAT 
router with IP x.x.x.x to OpenSIPS WAN IP.
Simple schema is:
2000 --> NAT Router --> OpenSIPS --> NAT Router --> 1000

I have following errors in RTP Rroxy :
Apr 25 11:00:11 rtpproxy[5181]: ERR:handle_command: command syntax 
error
Apr 25 11:00:34 rtpproxy[5181]: ERR:handle_command: invalid remote 
address: x.x.x.x70045415: No address associated with hostname

Where x.x.x.x is IP of NAT router, and 70045415 some garbage or ports?

In OpenSIPS I have error:
