Configuring VoIP Interfaces

You can use the VoIP Interfaces configuration pages to configure the VoIP interface on a device.

To configure a VoIP interface:

From the configuration page, as shown in Figure 1, select the VoIP interface that you want to configure—for example, vp-5/0/0
Enter information into the configuration page, as described in Table 17.
Click one of the following buttons:
- To apply the configuration and stay on the configuration page, click Apply.
- To apply the configuration and return to the main configuration page, click OK.
- To cancel your entries and return to the main page, click Cancel.

Table 17: VoIP Interface Configuration Page Summary

Field	Function	Your Action
VoIP Logical Interfaces
Add logical interfaces	Defines logical unit 0 as the physical VoIP interface to which you connect. You must define 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: 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.	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. Caution: Applying a new or modified IP address resets the TGM550. For existing configurations, ensure that the TGM550 configuration is saved and that the TGM550 module is carrying no voice traffic. You cannot specify more than one IP address.	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 device.	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 at least one and up to four Media Gateway Controllers (MGCs) with which the TGM550 must be registered. 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.	Type the IP address of the MGC. Click Add. To delete an IP address, select it in the MGC List box, then click Delete.
