•Select SIP to PSTN as direction.
• Enable both SIP peers as source peer.
• Enable the first PSTN interfaces as the Master destination.
• Confirm with OK.
6. Save the configuration in the main configuration interface.
If calls other than those beginning with 1 or 2 should also be directed to one peer, remove the condition from
the respective PSTN to SIP route and move the route to the end of the list.
Load balancing or failover between two SIP peers
If two SIP servers should be configured as load balancing or failover, configure the following:
1. Under PSTN Interface Configuration, enable and configure all required 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. If you configure a failover, SIP peer 1 (the master) should have
the option Alive check enabled. 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. For load-balancing configurations,
SIP peer no. 2 should be configured as the Master destination and for failover configurations it should
be configured as Slave destination.
• Confirm with OK.
4. Under Routing Configuration, create route no. 2 and do the following:
•Select SIP to PSTN as direction.
• Enable both SIP peers as source peer.
• Enable the first PSTN interfaces as the Master destination.
• Confirm with OK.
5. Save the configuration in the main configuration interface.
6. 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.*".
7. Under Routing Configuration, create route no. 3 and do the following:
•Select SIP to PSTN as direction.
• Enable both SIP peers as source peer.
• Enable the first PSTN interfaces as the Master destination.
• Confirm with OK
.
8. Save the configuration in the main configuration interface.
If calls other than those beginning with 1 or 2 should also be directed to one peer, remove the condition from
the respective PSTN to SIP route and move the route to the end of the list.
