I'm having much the same issues only I'm using Cisco 7960 phones. When I 
do a 'sip show peers' I'm getting times in excess of 300ms. A soft phone 
on the same network (x-lite), is reporting times of 4 ms. Related to 
this (I think), I'm getting audio issues. The person being called can 
hear the caller fine but the callee's voice drops in and out excessively.

I have qualify set to yes in the sip definitions for all the clients 
(Including the soft phone). Does anyone know what is causing this. I'm 
not aware what the sip ping times were earlier, but the audio issues 
seemed to have started spontaneously.

Anyone  have any idea regarding this?
