Fwd: [Serusers] SER+NAT+RTP PROXY

Hi List, Thanks for response for my previous mail. I am unable to establish voice connection between two user agents which are located one in public network and other is in provite network. I am using SER+NAT+rtpproxy as proxy servers. I have serched seruser mailing list for solution and I didn't find any. Please help me in below senerio. Elements ----------------- 1) UA 'X' ( in public internet with IP 209.233.XXX.XXX) 2) SIP SER with NAT helper(CVS version) + rtp proxy on same machine(http://www.portaone.com/~sobomax/rtpproxy.tar ) with one external public IP and internal privite IP) 3) UA 'Y' - in side private domain with 172.16.12.XXX) ip address. _______________ __________________ ________________ | Public | | Ser +NAT+rtpproxy | | UA 'Y' | |UA 'X' |--->Firewall ---> | 172.16.XXX.XXX |---->| 172.16.XXX.XXX | |209.233.XXX.XXX | | Internl IP | | | |______________| |__________________| |_______________ | Public IP 203.209.XXX.XXX I am trying to accomplish to make call from UA 'X' to UA 'Y'. i'e calls from public IP to private IP using SER as my signalling proxy and rtpproxy as proxy for RTP. FYI - I am using estara softphone as X and Pintel Softphone as Y. SER is succussfully etablishing connection between two use agents and but it is failed to forward rtp between two UAs. No voice. Please find attached ser.cfg file. I assume, may be because of below errors. Again thanks for help.
