[cisco-voip] Upgrading from CCM4.0 to CCM6.0

[Tim Reimers]

Hi -

 

I'm proposing in Erate funding requests that we upgrade our phone system
from:

 

Two Call Managers running 4.13

One Unity server running 4.0

One Emergency Responder server running 1.2

 

We have a mix of 7960 phones, 7905 phones, and 7912 phones

All switches are 3560 series - a few 3524 switches for additional phones
here and there.

All gateways are H.323 running 12.3 for the most part, and are

 

What I'm wondering is if people out there have any documentation details
they wrote up as part of their upgrade planning.

 

I'm going to be getting bids from vendors on this, and I'd love to know
of various and sundry gotchas, such as "7905 phones with an early serial
number aren't supported on CCM 6.0" and things like that, so that I can
know if a bidder has spotted and addressed potential problem areas.
