    The properties you can configure on a VoIP interface are displayed, as shown in Figure ###.

    Graphic will be added after changes requested in the Quick Config page are incorporated
  2. Enter information into the Quick Configuration page, as described in Table 111.
  3. Click one of the following buttons:

Function

Your Action

VoIP Logical Interfaces

Add logical interfaces

Defines the logical unit that you connect to the physical VoIP interface. You must define at least one logical unit for the VoIP interface.

Note:

You cannot define more than one logical unit for the VoIP interface. The logical unit number must be 0.

Click Add.

Logical Interface Description

(Optional) Describes the logical interface.

Type a text description of the logical interface to more clearly identify it in monitoring displays.

IPv4 Address and Prefix

Specifies the IPv4 address for the interface.

The following rules apply when you specify the IPv4 address:

  • You cannot specify more than one IPv4 address.
  • Do not assign the following IPv4 addresses:
    • A broadcast address (255.255.255.255)
    • A class E address (240.0.0.0 to 255.255.255.254)
    • A loopback address (127.0.0.0 to 127.255.255.255)
    • A multicast address (224.0.0.0 to 239.255.255.255)
  • A point-to-point connection needs to be configured between the VoIP interface and the TGM550. To configure the point-to-point connection, specify /32 as the subnet mask in the IPv4 address.

Type the IPv4 address with /32 as the subnet mask. For example:

10.10.10.1/32

Destination Address

Specifies the IP address of the TGM550.

For guidelines on assigning the IP address for the TGM550, see TGM550 IP Addressing Guidelines.

Note:

You cannot specify more than one IP address.

Caution:

When you specify the IP address for the first time, or modify an existing IP address, the TGM550 is reset when you apply the configuration.

Type the IP address of the TGM550—for example, 10.10.10.2.

Physical Interface Description

(Optional) Adds supplemental information about the VoIP physical interface on the router.

Type a text description of the physical VoIP interface in the box to clearly identify it in monitoring displays.

TGM Configuration    

MGC List

Specifies the IP address of the Media Gateway Controller (MGC) with which the TGM550 must be registered.

You can specify the IP addresses of up to four MGCs.

The first MGC in the list is the primary MGC. The TGM550 searches for the primary MGC first. If it cannot connect to the primary MGC, the TGM550 searches for the next MGC on the list, and so on.

  1. Type the IP address of the MGC.

  2. Click Add.

To delete an IP address, select it in the MGC List box, then click Delete.
