This object is used to configure either the domain name or the IP address of the Default Media Gateway Controller in standard dot notation. The complete address of a default MGC is cmposed of IP address/Domain Name and UDP port. xgcpMGCCfgaddress specifies address of the default Media Gateway Controller to which RSIP(RestartInProgress) message is sent whenever system starts up or line goes up. If DNS name is entered and the IP address is found, MG will send RSIP to the desired MGC. If no IP address is found or no such DNS name exists, no RSIP will be sent. If IP address is entered, MG will send RSIP to that address. If there is no response, it could be that the network is down or user misconfigures the address (IP address, Domain Name or UDP port number)
