Configuring the VoIP Interface (Required)

You must assign a local IP address to the vp-pim/0/0 interface on the Services Router and also a destination IP address to the TGM550, so that they can communicate with each other.

To configure the VoIP interface on the Services Router:

  1. Navigate to the top of the interfaces configuration hierarchy in either the J-Web or CLI configuration editor.
  2. Perform the configuration tasks described in Table 107.
  3. If you are finished configuring the router, commit the configuration.
  4. Go on to Configuring the Media Gateway Controller List (Required).

Table 107: Configuring the VoIP Interface

Task

J-Web Configuration Editor

CLI Configuration Editor

Navigate to the Interfaces level in the configuration hierarchy.

  1. In the J-Web interface, select Configuration>View and Edit>Edit Configuration.
  2. Next to Interfaces, click Edit.

From the [edit] hierarchy level, enter

edit interfaces vp-3/0/0

Select the VoIP interface—for example, vp-3/0/0.

In the Interface name column, click the VoIP interface name vp-3/0/0.

 

Create the logical unit 0.

Note: You cannot configure more than one logical unit on the VoIP interface. The logical unit number must be 0.
  1. Next to Unit, click Add new entry.
  2. In the Interface unit number box, type 0.

Enter

edit unit 0

Configure the source IPv4 address—for example, 10.10.10.1/32—for the VoIP interface.

The following rules apply:

  • 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)
    • An address with 0 as the first byte or an address with 0 or 255 as the last byte
  • The VoIP interface needs a point-to-point connection to the TGM550. To configure the point-to-point connection, specify /32 as the subnet mask in the IPv4 address.
  1. Under Family, select the Inet check box and click Configure.
  2. Next to Address, click Add new entry.
  3. In the Source box, type 10.10.10.1/32.

Enter

set family inet address 10.10.10.1/32 destination 10.10.10.2

Configure the destination IP address—for example 10.10.10.2—for the TGM550. The TGM550 uses this IP address to identify itself when communicating with other devices, particularly the Media Gateway Controller (MGC).

Caution: Applying a new or modified IP address resets the TGM550. For existing configurations, ensure that the TGM550 configuration is saved (see Saving the TGM550 Configuration) and that the TGM550 module is carrying no voice traffic.

You cannot specify more than one IP address. For more information, see TGM550 IP Addressing Guidelines.
  1. In the Destination box, type 10.10.10.2.
  2. Click OK until you return to the Interfaces page.
