asterisk users - Sep 2006 - Very high ping times from 7960 phones

I've asked this here before and never really got a response, so I'll try
again :)

I'm sure other people are using 7960 phones so maybe someone could have 
a quick look at what time sip show peers reports? When I do a 'sip show 
peers' all my cisco 7960 phones report times > 150ms. Every single one. 
I've scoured the settings on the 7960's and have looked and looked for 
why this might be the case. Cisco ata's (186) on the same network report 
~ 10 ms. An xlite softphone reports ~ 5ms regardless of what computer 
it's installed on.

Does anyone have any idea what might be causing this? I thought that it 
might just be a 'reporting' issue but there is definite latency there 
when I do an echo test. I'm running cisco sip firmware 8.2 on all the 
phones.


Thanks for any help

I have two 7960 phones with 7.4 firmware and sip show peers tells me that
response time is 70 and 72 ms.
Hope this helps.

All my Cisco phones show less than 75ms except for one (mine of course). 
I do have a switch in my cube that I use for extra ports and that's the only
real difference.

Do you have anything plugged into the extra network port on the phone?
What's in between your phone and the asterisk server?
