[Asterisk-Dev] Delay/latency on SIP phone with Asterisk

[chris.armour at sympatico.ca]

Hi folks,

Does anyone have any suggestions for how to reduce latency in Asterisk? I have just a small "hobby" system running on a PII 400 MHz with a SIP (X-Lite) softclient and a SIP hard-phone (Integrated Networks IN1002 - PA1688-based phone). 

I am experiencing a significant delay - perhaps 500 ms or so - on the Echo test and when one client calls the other, which is obviously not good.

I am running the Asterisk 1.0 release on Fedora Core 2 (2.6 kernel). I've been through the various articles on the WIKI without much joy.

Thanks!
