Dear Daniel and Kamailio'ns
Greetings,
I am working on kamailio server (4.0.x),whicch is integreted with media-proxy server (2.5.2) and it is all working fine in the point of SIP functionality.
And i have a set-up like this below, with this when the calls (audio/video) sessions started i am experiencing latency,jitter, echo's in audio calls and a choppy ,pixelled video :
KAMAILIO
| Android SIP client (IMSDroid) ---- Wi-Fi router ---- Switch (level 2) ---- Wi-Fi router ---- Android SIP client (IMSDroid)
(Total set-up runs on Intranet infrastructure).
When i call between two SIP clients, Calls are getting established successfully and RTP flow is also relaying using Media-proxy server. But the audio/video performnce is not good enough. I am experiencing all this Latency , jitter , Choppy pixelled video.
How can i resolve all this issues? What could be the problem ?
Ofcourse SIP proxy is not responsible all this problems (as i know ), But is there anything can be done on Media-proxy server ? Or anything Buffer settings can be done on Kamailio server side (or anything else) ? Even i changed Shared memory and Package memories to 512MB and 16MB respectively.
Anybody can guess what may be the problems that causes these issues ?
PS: When i tried 'ping' Clients IP addresses in Kamailio server PC, there is 20-30% packet loss also.
Please help me in resolving these issues.
Any help will greatly appreciate.
Regards, Ravi.
Hi Wingsravi,
You've answered your own question at the end..
20-30% packet loss is what is causing your issue. If you solve this your issues will go away.
This really is nothing to do with the software running at your proxy.
Regards Brian

Dear Brian,
Thank you for the reply,
But How can i approach with this issue ?
Why is this packet loss is logging in pings and how can i detect which node is causing this packet loss issue?
Is there anything can be done on Kamailio server like buffer settings?
can you guess there may be the Buffer setting issue for audio/video calls jitter/latency , pixelled video issue in clients?
please help me in reslving this issues.
Awaiting your reply.
Regards, Ravi.

Try to move to a wired solution, or if you are in a crowed wireless site, try switching the WiFi frequencies. Moving from 2.4 to 5 GHz can help .
I would place my bets on the wireless section. Maybe QoS, if your router can handle? El feb 2, 2014 8:48 AM, "Ravi" wingsravi777@gmail.com escribió:
