FXS GATEWAY WITH GXW410X [NO SIP SERVER REQUIRED]
Alternatively, the GXW410x can be used without a SIP Server. You can use it in conjunction with a FXS
Gateway (Ex. GXW400x) and still be able to originate and terminate calls from IP to PSTN and vice versa.
All you need to make sure is that the 2 gateways are able to locate each other (they should be on the
same LAN or on Public IP addresses).
In this diagram, configure the SIP Server field to be the IP Address of the other gateway (i.e. configure IP
address of FXS gateway to be SIP Server of GXW410x and vice versa). Please be sure you set SIP
Registration to No.
E
XPECTED C ALL F LOW : Analog Phone (GXW400x) picks up and dials destination PSTN number. The call
gets routed to the GXW410x which dials out the digit string onto the FXO Lines, thus reaching the
destination PSTN endpoint. On the reverse, incoming calls from PSTN endpoints will be routed
automatically to the FXS Gateway through the GXW410x.
