MGCP and H323 Call Preserve

Hi everyone.. Iam new to this community. I have a doubt which Iam not able to clear about call preserve in MGCP and H.323.

In Gatekeepers and Gateways text book I read that "MGCP supports call survivability for analog and T1 CAS calls, and MGCP does not support

call survivability for PRI and BRI calls " and "H.323 supports PRI call preservation, and H.323 does not support call survivability by default". Can anyone plz explain this in detail as Iam confused whether they preserve call or not... Thanks

MGCP and H323 Call Preserve

PRI calls will only be preserved with H323 by enabling call preserve service parameter and adding call preserve command on the GW. MGCP is backhauled to CUCM so calls are not preserved with MGCP. T1/E1 cas are not preserved with either protocol.

HTH,

Chris
