Configuring the PSTN (FXO) Gateway on the SPA3102 VoIP Outbound Call Routing (SPA3102) 6 VoIP Outbound Call Routing (SPA3102) On the SPA3102, calls made from Line 1 are routed through the configured Line 1 service provider, by default. You can override this behavior by IP dialing, through which the calls can be routed to any IP address that the user enters. The SPA3102 allows flexible call routing with four sets of gateway parameters and configurable dial plans. These settings are configured on the SPA3102 Voice tab > Line page. See "Gateway Accounts section (SPA3102)," on page 179. NOTE The PBX handles outbound call routing for the SPA8800. You can specify Gateways 1 to 4 in a dial plan by using the identifiers 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 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 The following table lists some examples.
