[cisco-voip] SCCP or SIP on Unity 5.0

[Pat Hayes]

(Dropping ask-icd-ivr-support at external.cisco.com as it doesn't seem relevant)

Right, they still appear as ports in Unity and can be monitored via
port status monitor, call viewer, etc. First call over the trunk shows
up on port 1, the second on port 2, etc.

I can appreciate what Ryan's saying re: keeping up with sccp port
counts on the CUCM side, but the Unity SIP integration is a bit less
mature than the SCCP. Unity has had a SCCP integration since...ever?
The SIP integration is the new kid on the block, and hasn't been
adopted widely. It also has the limitations of:

1. No Unity failover/secondary server
2. No MOH on supervised transfers

I'd lean toward skinny, especially if you are under the 144 ports (I
think that is the current max for the port wizard in CUCM). Even if
you are over 144, you can create a second set (CiscoUM2-VI, etc) and
add them to the same line group.
