Connect two SIP peers to two PSTN interfaces exclusively

If you choose to connect two SIP peers to two PSTN interfaces, so that each SIP peer may use one interface

exclusively, then carry out the following configuration steps. The procedure is similar if you need to configure

more PSTN interfaces, e.g., three PSTN interfaces to three SIP peers.

1. Under PSTN Interface Configuration, enable and configure the two PSTN interfaces. Confirm with OK.

2. Under SIP Peer Configuration, create both SIP peers and make sure the entry in Domain matches exactly

the domain used by the SIP peer in its SIP address for outgoing calls. Do not enable the option Default

PSTN to SIP Peer for any of these peers. Confirm with OK.

3. Under Routing Configuration, create route no. 1 and do the following:

•Select PSTN to SIP as direction.

• Enable the first PSTN interface as source.

• Enable the first SIP peer configured in step 2 as the Master destination.

• Confirm with OK.

4. Under Routing Configuration, create route no. 2 and repeat step 3 for the second PSTN interface and the

second SIP peer.

5. Under Routing Configuration, create route no. 3 and do the following:

•Select SIP to PSTN as direction.

• Enable the first SIP peer configured in step 2 as source peer.

• Enable the first PSTN interfaces as the Master destination.

• Confirm with OK.

6. Under Routing Configuration, create route no. 4 and repeat step 5 for the second PSTN interface and the

second SIP peer.

7. Save the configuration in the main configuration interface.

Connect two SIP peers to the same PSTN interface

If you want to connect two SIP peers to the same PSTN interface so that all calls from the PSTN are sent to the

first SIP peer if the numbers begin with "1" and to the second peer if the numbers begin with "2", configure the

parameters as follows:

1. Under PSTN Interface Configuration, enable and configure the PSTN interface. Confirm with OK.

2. Under SIP Peer Configuration, create both SIP peers and make sure the entry in Domain matches exactly

the domain used by the SIP peer in its SIP address for outgoing calls. Do not enable the option Default

PSTN to SIP Peer for any of these peers. Confirm with OK.

3. Under Routing Configuration

, create route no. 1 and do the following:

•Select PSTN to SIP as direction.

• Enable the first PSTN interface as source.

• Enable the first SIP peer configured in step 2 as the Master destination.

• Under Conditions, click Add and set the Called address to "1.*".

• Confirm with OK.

4. Under Routing Configuration, create route no. 2 and repeat step 3 for the second SIP peer with the only

difference that the called address condition for this route is "2.*".

5. Under Routing Configuration, create route no. 3 and do the following:
