The following guide is for configuring a Grandstream HT704 with a VoIPOffice extension.

You will need:

• The VoIPOffice IP address – e.g. '77.240.xxx.xxx' 
• The Extension number – e.g. '1001' 
• The extension password/Secret (can be found by going to the edit mode of that specific extension, see the screenshot below) 

1-) Connect an analogue phone to port 1,2,3 or 4.

2-) Insert an Ethernet cable into the LAN port of the HT704 and connect the other end of the cable to an uplink port (router, modem, etc.).

3-) Dial **** from the handset to hear the configuration menu.

4-) Dial 02 to hear the IP address. Make a note of that IP address.

5-) On a computer which is connected to the same subnet as the Grandstream HT704, open a web browser and type the IP address (including the dots) into the address bar.

6-) You should now see the login screen. Enter the password 'admin' to log in.

7-) Go to 'Profile 1' and fill in the Primary SIP Server with your VoIPOffice IP address/ URL (e.g. 77.240.xxx.xxx)  then click 'Apply'.

8-) Go to 'FXS ports' and in the first SIP Account line, fill in the following details:

• SIP User ID: Extension Number
• Authenticate ID: Extension number
• Password: the password/secret of the Extension
• Name: Extension number
• Enable Port: Yes

9-) Click on Apply and then on Reboot.

10-) When the device has rebooted, log into the VoIPOffice and go to 'Monitor'. If the registration has been done correctly, the extension will show as 'Online'.
