Static Routing Table

Static Routing Table is required when you have more than one router (Gateway) in your network and you want

SETU ATA211 to send packets to multiple routers/gateways for different types of calls.

To illustrate this with an example, two Local Area Networks, Network A and Network B, are connected through

Frame Relay/ MPLS network to give access to local resources and also to make Peer-to-Peer calls.

• Both sites are also connected to public IP network:

• to give internet access to local hosts.

• to access the DID service provided by ITSPs to make PSTN/ GSM calls over the IP network.

• SETU ATA211 is connected at both sites.

• These sites are also connected to public IP network for the following reasons:

• To give internet access to local hosts.

• To access DID service provided by ITSPs to make PSTN/ GSM calls over IP network.

• SETU ATA211 is connected at both sites, behind a router.

• Network A and Network B are in different subnets.

• You can configure only one default Gateway address in SETU ATA211 to send IP packets.

• Now, as SETU ATA is connected behind two Routers, it will not be able to determine where to route the IP

packets.

• So, either Peer-to-Peer calls or Proxy calls can be made at a time between Network A and Network B.
