B. FXS Gateway with GXW410x [No SIP Server required]

Alternatively, the GXW410x gateway can be used without a SIP Server. It can be used in conjunction with

an FXS Gateway (Ex. GXW400x) and calls can still be originated from the IP network and terminated on

the PSTN network and vice versa. All you need to make sure is that both gateways are able to locate

each other (i.e. they should be on the same LAN or have public IP addresses).

GXW400X & GXW410X SCENARIO/TOLL- FREE CALLING BETWEEN LOCATIONS

If you setup resembles the one in this diagram, you need to configure the SIP Server field to be the IP

address of the other gateway (i.e. configure the IP address of GXW400x gateway to be the SIP Server for

the GXW410x gateway and vice versa). Please be sure you set SIP Registration to No.

EXPECTED CALL FLOW: An analog Phone (connected to the GXW400x gateway) picks up and dials the

destination PSTN number. The call gets routed to the GXW410x gateway which dials out the digit string

onto the FXO Lines, thus reaching the destination PSTN endpoint. On the reverse, incoming calls from

the PSTN endpoints connected to the GXW410x gateway will be routed automatically to the analog

endpoints connected to the GXW400x gateway.
