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,

Subject: [asterisk-users] sip show peers

Hello guys,

Is there anyone who could explain me some stuff about sip show peers ?

108/108                    10.1.1.40                   5060     OK (1
ms)
107/107                    10.1.1.246       D          51074    OK
(101
ms)

The port seems different here, and the main difference is that the
extension 108, is a server with a fixed IP
107, is a client with a softphone (X-Lite) and a dynamic IP.

Why the diffrence in the port ?
And why the difference in the reponse time ?

We are on the same physical network, a ping is giving me a response of
1ms for each.
Is it because the softphone is with a dynamic IP and Asterisk is
treating this differently ?

Thanks,
<SNIP>

A SIP ping and an ICMP ping are two different entities.  The SIP ping
operates at a higher level in the OSI stack than a simple ICMP ping.
This means that whatever is receiving the ping has to do more work to
decode it, and respond.  I wouldn't worry about the latency difference
as the SIP Ping is prioritized a bit more by a computer which is
multitasking than by a hard phone which is not.  As for the port, they
simply chose to negotiate on a higher port.  You might check your X-Lite
settings, but I don't think this will break anything!

Andrew
