[Serusers] latest rtpproxy + ser-0.8.14 + nathelper!!

Hi! I have some problems with rtp proxy. And the syslog tells that my rtpproxy can work (enable!!) ---------------------------------------- UA1: 10.10.54.131 (caller), behind NAT UA2: 218.171.144.86 (callee), public Internet SIP UA: Windows Messenger 5.1 SIP Server: ser-v0.8.14 Load module: nathelper RTP Proxy: latest rtpproxy (not portaone) NAT: CiscoSymmetric NAT ----------------------------------------- [Problem] Callee can hear caller's voice, but caller can't hear callee's. The the packet analysis is like this http://sip.csie.ncyu.edu.tw/~coolboy/calleereceiveinvite.JPG the line ( c= IN IP4 140.130.201.15 ) is NAT Server's IP address, not rtp proxy's IP address(140.130.175.2). I use force_rtp_proxy("140.130.175.2" ); to change c=IP4 with IP address(140.130.175.2), but it seems doesn't work. ----------------------------------------- Does anyone know how to solve my problem and the reason? It's very important to me. Thanks a lot !! ----------------------------------------- [Question] 1. Does c=IP4 get from rtpproxy if I use rtpproxy.?? And how they operate?? 2. I want to compile the latest nathelper module with FreeBSD system. I've read the 'Makefile', but it says "don't run with this Makefile, you should use 'master.Makefile' ". Does anyone can tell me how to do?? --== Mail Via Ncyu Mail ==--
