A. IP PBX / SIP Server with GXW410x
A SIP proxy server such as Asterisk or a SIP registrar server can be deployed with the GXW410x series
gateway. In this environment, the SIP server handles SIP registration and call control and the GXW410x
processes media conversion between IP and PSTN calls.
There are 2 ways to configure GXW410x when using it with a SIP Server:
1. With SIP accounts configured on Channels page. In this case, the GXW410x gateway acts as
an endpoint requesting registration from the SIP Server. Under the Channels page you will need
to fill in the information like SIP User ID, Password, etc. Now, when calls are made from an IP
phone, the call will be routed to the SIP Server which will forward it to one of the SIP accounts on
the GXW410x, which will then forward it to the PSTN line.
2. Without SIP accounts. In this case, you simply have to configure the SIP Server to perform
forwarding of the SIP INVITE message with the FXO destination number to the gateway’s IP
Address. The GXW410x gateway will receive the digits and immediately forward them on the
FXO lines to the destination PSTN. Most of the configuration on the Gateway for this case will
remain default, except Stage Method needs to be set to 1, and SIP Server IP Address/DNS name
has to be filled.

For incoming calls from the PSTN analog endpoints to the GXW410x gateway, the device will auto
forward each call to a configured IP extension. The SIP Server can then route the call based on its own
configuration or IVR system.
