[cisco-voip] CCM5/6/Express with SIP or SCCP phones?

[Ed Leatherman]

Jozef,

Just from my perspective, we will not be running SIP on endpoints until
there is some very compelling reason to switch. Right now we use SCCP and it
has all the features we need, and under call manager at least it is tried
and true.

Is there anything that SIP does right now on callmanager that SCCP does not
do for general end-user phones?
