Grandstream GXW410X FXO

The Grandstream GXW410X provides FXO - to answer your backup landline/faxline etc. We are assuming here that this is on a LAN and you have configured a few Wifi boxes and can get it set up with an IP address.

The sane way to set it up is via a web browser. If you plug it in it will get an IP from DHCP - find the IP in the logs and connect with your favorite browser.

You likely will want to upgrade to the latest firmware version ( as of 2013-09)- this means having a TFTP server up and running (as of the last version, it did not honor the http setting)

Under Maintenance - Upgrade/provisioning point it to your server. It will assume the root directory of your TFTP - You can use the Firmware File Prefix to set the name of a directory - such as GXW410x. and put the firmware goodies you get from grandstreams web sit in it. A similar procedure is used to restore saved config files as described below.

In Debian this means installing tftpd-hpa then edit /etc/default/tftpd-hpa Change the TFTP_OPTIONS line to:

TFTP_OPTIONS="--secure -vvvv"

This will provide a bit of logging to /var/log/syslog -- you can change it back after you have everything working.

Once you have your firmware up-to-date don't change any thing not listed here.

Account Active Yes
Account Name ( set to what you have in your local DNS, hosts etc).
Sip Server ( IP of your freeSwitch box)
Outbound Proxy ( IP of your freeSwitch box)
Channel (line number you have phone line plugged into )
SIP user ID (Some ID you have set up in the FS directory )
Authenticate ID (Same ID again )
Authen Password ( Password for that ID )
SIP Account - account1 ( what we set up above )
User ID ( here you can do a couple things - 
 if you want all lines to call user ID 1234 set ch1-4:1234;
 If you want line one to go to 1234 and line 2 to go to 2345  - ch1:1234;ch2:2345;
Set this to ch1-4:1;

You can run the line Analysis as per grandstreams instructions.

Backup your config

Hit the download Configure - which will do a file dialog to save your config. This file should be renamed as below

Only this does not work correctly - I have resorted to doing screen grabs of the web interface for a backup.

Restore your config

You can set up your TFTP server in a similar way as for getting software updates to get this file that you renamed cfg000b82123456 where the digits after cfg are the mac address of your grandstream unit. You have to run what you download through some software to create a file to upload - I have done all this, but I am not getting a complete backup this way.

FS extention for incoming calls

Calls will come in the user ID you set above.

FS calling out

Set up a bridge line as below where is the IP of your grandstream box.

<action  application="bridge" data="sofia/internal/${destination_number}@"/>

There does not appear to be a way to choose the line to call out on?
