Configuring VoIP subnet routing
In its simplest configuration, the 6400-S acts as a proxy for a soft-switch or
H.323 gatekeeper on its immediate Provider subnet. Because these devices
reside on the same subnet as the 6400-S, packets proxied by the ALG function
do not require additional routing information.
The 6400-S can support a VoIP call-control server or H.323 gatekeeper on it's
Provider side but not located immediately on the Provider-side subnet by
configuring VoIP Subnet Routes.
Using the VoIP Subnet Routing feature, the 6400-S can be configured to serve
these remote devices. Three pieces of information are required for each subnet
containing the VoIP call-control server or H.323 gatekeeper:
• The IP Network address.
• The Netmask.
• The Gateway.
You can configure up to 20 VoIP subnets.
To configure VoIP subnet routing:
1. In the navigation bar, select System.
