| Configuring the HT818 |
|
These instructions are based on Grandstream HT818 firmware version 1.0.10.6; if you are running a different firmware version, some menus/settings may be different. These instructions are also based on using the HT818 in its factory default configuration, which obtains a dynamic IP address automatically from your router using DHCP. For information on configuring your HT818 with a Static IP address, please refer to the HT818 User Manual.
In this guide we will go through configuring the HT818 in order to register to the Callcentric servers so that you will be able to place and receive calls using your Callcentric account. Before moving forward, please ensure that you have properly added the device to your network by connecting it to your router or gateway.
We recommend that you read each step through in its entirety before performing the action(s) indicated within the step.

 | |
STEP 1
|
Connect your HandyTone to your router with the supplied Ethernet network cable. Next, connect your phone to the HandyTone. Finally, plug the supplied power cable into the HandyTone.
|
STEP 2
|
Wait 60 seconds after plugging your HT818 in.
Pick up the phone connected to the HT818 and dial the * key on your phone 3 times.
Have a pen and paper ready. When you hear the message - Enter a menu option please enter 0 2 on your phone. You will now hear a message giving you the IP address of your HT818, such as: "192.168.001.010". Please write this number down.
Open a web browser on your computer such as Chrome or Firefox and enter the IP address you wrote down in the previous step into the address bar (I.E. where you would normally enter www.yahoo.com).
Important Note: Some browsers will require you to remove leading zero's ( 0 's ) in the IP address. For example if you heard "192.168.001.010", you should change this to "192.168.1.10".

STEP 3

You should now see a page that looks like this:
Enter the password for the HT818 in the password field. The default administrator password for the HT818 is admin.
