You won't get FXO MGCP caller id on CUCM 6.x.

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?
