Grandstream Networks GXW-410x APPLICATION DESCRIPTION

APPLICATION DESCRIPTION

A SIP proxy server such as Asterisk or a SIP registrar server can be deployed with the GXW-410x series.

In this environment, the SIP server handles SIP registration and call control and the GXW-410x

processes media conversion between IP and PSTN calls.

There are 2 ways to configure GXW410x when using with a SIP Server:-

1. With SIP accounts configured on Channels page. In this case, the GXW acts like an endpoint

requesting registration from the SIP Server. Under the Channels webpage you will need to fill in

the information like SIP User ID, Password, etc. Now, when you try to make calls from IP, 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 gateways IP

Address. The GXW410x 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.

Anywhere in the world

For incoming calls from the PSTN analog endpoints to the GXW410x, 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.

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
