When I try to config the MGCP using the ccm-manager config server, in "show ccm-manager" it shows the gateway is registered to UCM successfully:
Priority Status Host
============================================================
Primary Registered 192.168.20.2
First Backup Backup Ready 192.168.20.1
Second Backup None
However when I do "show isdn status", the Layer 2 status shows:
State = TEI_ASSIGNED
A router reload solved the problem, you should see
State = MULTIPLE_FRAME_ESTABLISHED
in "show isdn status" Layer 2 status.

Thanks Boris, I tried your second method, although it shows MULTIPLE_FRAME_ESTABLISHED, the call cannot route through and reload the router is the only way I have found it working.
Because you have to do:
no mgcp bind control source-interface ..
mgcp bind control source-interface ..
no mgcp
mgcp
show isdn status
try to call and it will work :)
