Is the port configured on CM properly? In the right port, etc? Does it show registered there? MGCP auto generate the dialpeer for you and you should not need to touch it on the GW, only CM config should be of your concern.
Please check 'show ccm | i Name' against the name you've entered on the MGCP gateway page and check for typos / missing domain name.
Otherwise, check 'show voice port summary' and 'show voice call summary' to make sure the ports are in an operational state.
Then, do a 'debug mgcp packet' and see what's up with the messaging, and see which side is rejecting the call. The gateway could be sending an "Unknown Endpt" or the CUCM could be sending back a 500 rejection message, among other things.
