MGCP vs H.323MGCP - IETF standard = Media Gateway Control Protocol.Master/Slave Protocol - Call Agent (CUCM) is used to control the gateway ports.Complete control of dial-plan from the CUCM.Centralized call processing (CUCM). Requires dial-peers only for SRST.Survivable end point by default-

H.323 - ITU standard = ITU Umbrella recommendation.Peer to Peer Protocol.dial-plan controlled locally from H.323 gatewayDistributed call processing.CUCM/PSTN sends call to gateway & gateway decides (based on dial-peer) which port/call managerto use for outbound/inbound calls.
