Hi all, I've done a basic install of 10.1.2 to have a play with the new ConfBridge application and have noticed high latency when in a conference. It's to the order of 900ms or so which is just too much for a conference to work well. I can account for about 120ms of that latency, but not the rest. With two SIP handsets in the conference, worst case latency from handset to handset (Handset --> Local Asterisk --> Gateway Asterisk --> PSTN --> Gateway Asterisk --> Conference Asterisk --> Gateway Asterisk --> PSTN --> Gateway Asterisk --> Local Asterisk --> Handset) is measured at 62ms which leaves 780ms or so latency created by the conference bridge. The box I'm testing ConfBridge on is a CentOS 5.7 x86_64 box with a Xeon E31220 and loads of RAM. Whilst a two party conference is in progress, 'top' shows a load average of 0.05 and that Asterisk is using 0.5% CPU. Assuming the ConfBridge works in Slin, 'core show translation' table shows a 6ms (which does strike me as rather high - I get much lower figures on much older hardware). There is no jitter buffer and the mixing interval is 10ms. I'm pretty sure there are no bottlenecks in the hardware!! I was wondering if anybody else had experienced the same thing and/or whether this is normal behaviour. Can I work it faster? Any ideas, or should I just accept this? Nicholas.
