[cisco-voip] cisco 8851 problematic

[Brian Meade]

There's an issue where some phones don't ring-

For your issue, I'd do some packet captures at CUCM and the phones
ideally.  CallManager traces/Console logs may be a good start if you can't
get captures.

I've seen this before and it was caused by network issues where the other
phones didn't receive the Cancel.

How many phones have the shared line on it?  It could be that CUCM node is
getting overwhelmed.
