12.4.3.4 VoIP Interfaces with Multiple Default Gateways

Below is a configuration example using default gateways per IP network interface. In this
example, the default gateway for OAMP is 192.168.0.1 and for Media and Control it is
200.200.85.1.

A separate Static Route table lets you configure static routing rules. Configuring the
following static routing rules enables OAMP applications to access peers on subnet
17.17.0.0 through the gateway 192.168.10.1 (which is not the default gateway of the
interface), and Media & Control applications to access peers on subnet 171.79.39.0
through the gateway 200.200.85.10 (which is not the default gateway of the interface).

Configuring Static IP Routes

The Static Route table lets you configure up to 30 static IP routing rules. Using static routes
lets you communicate with LAN networks that are not located behind the Default Gateway
specified for the IP network interface, configured in the Interface table, from which the
packets are sent.
Before sending an IP packet, the device searches the Static Route table for an entry that
matches the requested destination host/network. If an entry is found, the device sends the
packet to the gateway that is configured for the static route. If no explicit entry is found, the
packet is sent to the Default Gateway configured for the IP network interface.
You can view the status of the configured static routes in the IP Routing Status Table page.
This page can be accessed by clicking the Static Route Status Table button, located at
the bottom of the Static Route table page, or it can be accessed from the Navigation tree
under the Status & Diagnostics tab (see ''Viewing Static Routes Status'' on page 619).
The following procedure describes how to configure static routes in the Web interface. You
can also configure this using the table ini file parameter, StaticRouteTable or the CLI
command, configure voip/routing static.

To configure a static IP route:
1. Open the Static Route Table page (Configuration tab > VoIP menu > Network >
Static Route Table).
2. Click Add; the following dialog box appears:
