Q is this a correct statement
The main reason I would use MGCP over h.323 is for failover. If you are using a h.323 gateway and your primary callmanager goes down the calls will be dropped. With mgcp the gateway calls will be failed over to the secondary callmanager and the calls will stay up.
According to H.323 gateway confg
There is 2 VOIP statements apply with a
Session target ipv4: Primary Call manager IP address
And Subscriber IP address
Can you explain?
Thx

This is true. Q.931 terminates on CUCM with MGCP. If CUCM goes down, the q.931 channel needs to failover to the router to take calls for SRST, which means active calls will drop.

To go along with Steve's note, this would imply that MGCP calls would drop when connection is lost to Call Manager, where with H323 as q.931 is terminating at the gateway itself and not Call Manager, if contact is lost with Call Manager, the call will not drop and will be preserved.
