Chatter for IP Phones

| We've got 7960 and 7940 IP Phones plugged into CCM 4.0(2a).. What
should I expect be the amount of bandwidth Idle phones are using? We're
seeing about 100Kbp/s (~12KBp/s)per ethernet interface. I wasn't sure
if that was normal for idle phones. Seems excessive to me for a phone
that just issues keepalives every few secs.

| the skinny/SCCP protocol is a bit chatty as it requires
keeping an underlying tcp connection going which requires that tcp
overhead not counting the data that is transported within the tcp session..

| CM 4.1(3) load 7.1(2) a 7960 with idle URL running (and cycling every 5
secs) isn't sending enough traffic for the switch to consider it 1pps
over a 30 second load-interval.
Do you have PCs behind those phones?
