Dear Daniel, Thank you again,
Ya i am investigating on this issue, by the way can you give any comments on my questions in the previous mail? I just wanna clarify those things to rectify this packet loss issue. i googled about those questions but still ended with the same confusion status and didnt got any prompt information. And here below is the attachment, that shows RTP packet loss(using wireshark) in my set-up. Can you please suggest me how can i troubleshoot this RTP packet loss issue ?
And in that Attachment the IP addresses are like this: 192.168.2.235 and 192.168.2.239 are clients and 192.168.2.52 on which RTPproxy and Kamailio are running.
Awaiting your reply.

Hi Ravi, if you media/rtp proxy is receiving such packet loss, it means that something behind him is cutting the traffic off, somehow. So you should investigate there, in their configuration. If your analysis is right, it seems your loosing around 80% of your packets.
Do you have any router, firewall something between clients and mediaproxy ?

Dear Daniel,
Thank you for the response,
Do you have any router, firewall something between clients and mediaproxy ?
Ya I have Routers And switch in between clients and Rtpproxy, My set-up is as follows:
SIP Clients<------>WAP+WiMax CPE <------> WiMax Base station <----> RTPproxy+Kamailio server.
Both the SIP clients A and B are connected to Wi-Fi Access point (WAP). When i run RTPproxy server with kamailio server then only RTPproxy receiving very High RTP packet loss, But when only running kamailio server without RTPproxy server Then there is lesser RTP packet loss (< 5%).
Whats could be the reason for this behavior ?
How can i reduce this RTP packet loss ?
I hope you could help me.
Awaiting your reply,
Regards, Ravi

Hi, When you don't use RTPproxy, RTP traffic is sent end-to-end. What is the RTP path in case of client-to-client RTP ? Is it the same ?

Dear Daniel,
My whole set-up remains same in both the cases, only change is running RTPproxy with kamailio server and without running RTPproxy server. Now When i run RTPproxy with kamailio server, RTP packets has to reach up to RTPproxy server to get relay to other end client right ? But how this client-to client RTP traffic gets transfer? i mean in client-to-client method, is RTP packets are passing through only WAP (in my above set-up) to reach other end client ?
