[cisco-voip] Connecting analog fxo to CUCM (what protocol?)

[Madziarczyk, Jonathan]

Running CUCM 6.x

2821 with 2 fxo cards

 

Nothing special, routing calls from my PRI on CUCM to another PBX for
things like TTY and automated dialers (elevators, etc) and voice calls.

 

I feel as if there is a plethora of different options for connecting the
FXOs to CUCM

H.323

MGCP

Is it still just user preference or are there reasons to go with one or
the other for something like a TTY?

 

I think I remember hearing caller id now works with MGCP (used to only
be H323)

 

 

 

Suggestions?  Ideas?
