Configuring the Media Gateway Controller List (Required)

To provide telephony services, the TGM550 must be registered with a Media Gateway Controller (MGC) running the Avaya Communication Manager software. You can configure the IP addresses of up to four MGCs that the TGM550 can connect to in the event of a link failure.

The MGC list consists of the IP addresses of the MGCs to connect to and the order in which to re-establish the H.248 link. The first MGC on the list is the primary MGC. The TGM550 searches for the primary MGC first. If it cannot connect to the primary MGC or loses its connection to the primary MGC, it attempts to connect to the next MGC on the list, and so on.

The MGC list is stored in the TGM550. It is not written to the JUNOS configuration file.

You can also log in to the TGM550 and configure the MGC list. For information about configuring the MGC list on the TGM550, see <insert name of Avaya document>.

To configure the MGC list:

1. Enter operational mode in the CLI.
2. To configure the IP addresses of the Media Gateway Controllers, enter the following command:
   user@host> request tgm fpc slot slot-number tgm-configuration "mgclist=ipaddress1,ipaddress2,ipaddress3,ipaddress4"

   For example, to configure the primary MGC with the IP address 172.16.0.0 and the secondary and tertiary MGCs with the IP addresses 10.10.10.30 and 10.10.10.40 for the TGM550 installed on slot 2 of the chassis, enter

   
   user@host> request chassis fpc slot 2 tgm-configuration "mgclist=172.16.0.0,10.10.10.30,10.10.10.40"
3. Log in to the TGM550. For information about logging in to the TGM550, see Connecting to the TGM550 CLI.
4. Ping the IP addresses of the configured MGCs to ensure that the IP addresses are correct. For example, to ping the IP address of the primary MGC, enter
   TGM550-00<root># ping 172.16.0.0
5. To verify that the MGC list is configured correctly, see Verifying the VoIP Configuration.
