Hi,
MGCP - Centralised configuration of translation etc on the CUCM.
When an MGCP gateway fall back in to SRST it has to invoke a fallback protocol usually H323. You therefore need to configure
ccm fallback and a minimul dial peers etc for SRST.
H323 - You need to configure the dial peers etc locally on the router. Uses its defaault protocol of H323 for SRST.
You need to make a decision.
More config on CUCM (MGCP)
or More config work on the gateway H323.
MGCP gateway shoew as registered on CUCM due the protocol being client/server.
H323 gateways show as unknown status as this is a PEER to PEER protocol
If you are using partial E1 trunks (IE less than 30 B-Channels on the trunk) to the pstn etc is better practise to use H323

Hi,
There is a document that compares MGCP and H.323 Voice Gateway Protocol
http://www.cisco.com/en/US/tech/tk1077/technologies_tech_note09186a00806fedbe.shtml
MGCP is easier to configure but has limitations because CCM takes all decisions and only works on DNIS.
H323 requires more configuration because of dial-peers but work with ANI, DNIS and redirect number. You have a lot more control.
