RE: [Serusers] Scalability Question
by Darren Sessions 10 Dec '03

10 Dec '03

Here is a little more insight into what I envision to be the core network. Hopefully this will help in the scalability question I'm desperate to get a better understanding of. I'm just not sure if I've under-engineered this, or over-engineered it - and what I can get rid of to save money or what more I need to spend. Thanks again for all the help! - Darren --- Architecture = Intel i386 Bandwidth = DS3 to OC12 Population Size = Initially, a 100k user base at 10-1 ratio (10,000 simultaneous calls) and a 100-1 ratio for voicemail (1,000 simultaneous calls).

Ethereal also can do all the analysis: mark an UDP (RTP) packet, right-click, decode as ... select RTP. Then mark the RTP packet, ->Tools->Statistics->RTP stream->Analyse. There you will see a list of all RTP packets with jitter/packet loss analysis. Furthermore you can save the payload to disc and listen to it. What causes the choppy audio - packet loss or jitter? Is the problem caused by using X-lite as sender or receiver?

Not able to register. I have given proxy ip : iptel.org and port : 5060 What values should be given in outbound proxy and port Enable NAT : yes My phone is working behind firewall & NAT.

I recommend that you add log-messages to certain points in your script like in: http://www.iptel.org/ser/doc/seruser/seruser.html#AEN812 You can watch the messages during an INVITE using: tail -f /var/log/messages maybe then you can find the problem yourself.
