[cisco-voip] VGW IP switch

[Kevin Thorngren]

The IP Address shown in CCMAdmin is dynamic.  The only dependancy is 
the hostname of the GW.  You should be able to turn off MGCP (no mgcp 
in config mode) change the IP address of the GW and the MGCP bind 
commands then re-enable MGCP.    The GW should register right away 
(assuming a Cisco based Metro E solution ;-) using the new IP Address.
