Also, gw0 represents the internal PSTN gateway via the FXO port. You can specify in the dial plan to use gwx (x = 0,1,2,3,4) when making certain calls. In general, you can specify any gateway address in the dial plan. In addition, three parameters are added that can be used with call routing: • usr-User-id used for authentication with the given gateway • pwd-Password used for authentication with the given gateway • nat-Enable or disable NAT mapping when calling the gateway Table 1-31 lists some examples.

Configuring the PSTN Gateway (FXO)
How PSTN-To-VoIP Calls Work
Gateways 1 to 4 can be specified in a dial plan with the special identifier gw1, gw2, gw3, or gw4. Also,
gw0 represents the internal PSTN gateway via the FXO port. You can specify in the dial plan to use gw
x
(
x
= 0,1,2,3,4) when making certain calls. In general, you can specify any gateway address in the dial
plan. In addition, three parameters are added that can be used with call routing:
•
usr—User-id used for authentication with the given gateway
•
pwd—Password used for authentication with the given gateway
•
nat—Enable or disable NAT mapping when calling the gateway
Table 1-31
lists some examples.
You can set up multiple PSTN gateways at different locations and configure Line 1 to use a different
gateway when dialing specific numbers.
