[asterisk-users] sip show peers

[Eric Rousse]

Hi Andrew,

Thanks for the response. Interesting.

But one thing though, both extensions are softphones actually.
The one on 108, is actually VoiceGenie that I'm testing with Asterisk.
But I'm trying to explain why I'm getting some glitch with the systems 
sometimes with my softphone,
and I thought the response time of 101ms, was the answer. Is there 
anything I can do to improve that response time ?

Thanks,
