Step 3. If you are using an external DNS to resolve domain names, proceed to Step 3.
Step 3 Type the adddnip command, resol-num, domain-name, ip-addr, and addr-order argument values, and
press Enter to add the IP address for the domain name you added in Step 1. Specify the arguments with
the following values:
•resol-nu m (resolution number of the domain name): In the range from 1 to 88.
•domain-name (call agent name): In the range from 1 to 64 alphanumeric characters.
•ip-addr (IP address which corresponds to domain-name): IP address, which must be in the following
format—nnn.nnn.nnn.nnn.
•addr-order (IP address resolution preference order): In the range from 1 (highest) to 8.
Step 4 Type the addmgcgrpentry command, mgc-group, mgc-num, and mgc-priority argument values, and
press Enter to add the MGC to a redundancy group. Specify the arguments with the following values:
•mgc-group (call agent redundancy group number): In the range from 1 to 8.
•mgc-num (protocol number): In the range from 1 to 8.
•mgc-priority (preference of the MGC within the group): In the range from 1 ( highe st) t o 8 .
Step 5 Type the cnfmgcgrpparam command, mgc-group, state-change-notify, and the optional mgc-priority
argument values, and press Enter to change the parameters of the MGC group , if neede d.
Note This step is optional; use only if you need to change the MGC group parameters.
Specify the arguments with the following values:
•mgc-group (call agent redundancy group): In the range from 1 to 8.
•state-change-notify (state change message notification):
– 1 = Enable (default)
– 2 = Disable
•|mgc-priority| (call agent priority): In the range from 0 to 8 (default = 1)
Step 6 Type the addmgcgrpprotocol command, mgc-group and protocol-num argument values, and press
Enter to associate a call agent redundancy group with a gateway control protocol. Specify the arguments
with the following values:
•mgc-group (call agent redundancy group): In the range from 1 to 8.
•protocol-num (gateway control protocol): In the range from 1 to 8.
Step 7 Repeat Step 1 through Step 6 for each call agent that you need to make active in your application.
You have completed setting up call agents and media gateway control protocols. Proceed to the
“Configuring Gateway Control Protocols” section on page 4-47, if necessary.
