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).
