| Configuring the DP752/DP730/DP722 |
|
These instructions are based on Grandstream DP752 firmware revision 1.0.11.2. If you are running a different firmware version, some of the menus and settings may be different. These instructions are also based on using the DP752 in its factory default configuration, which obtains a dynamic IP address automatically from your router using DHCP. For information on configuring your DP752 with a Static IP address, please refer to the DP752 user manual.
In this guide we will go through configuring the DP752 in order to register to the Callcentric servers, so that you will be able to place and receive calls using your Callcentric account. Before proceeding, please ensure that you have properly added the device to your network by connecting it to your router or gateway.
We recommend reading each step through in its entirety before performing the action(s) indicated within the step.
Note: Although this device supports many advanced features/options, this guide will only detail the specific settings which are required to establish basic connectivity between your DP752 and our service. If you need additional assistance with any specific issue please let us know.

| Step 1 |
Pairing to the base station |
|
By default, your handset (either the DP730 or DP722) is not paired with the DP752 (the base station). To pair your handset(s) to your base station, please follow the instructions below. If your handset is already paired with your base station, please proceed to the "Step 2" of this guide.
Assuming the base station is fully powered and your handset is fully charged, press/hold the radio/page button on the base station (indicated by the icon).
Next, while the radio icon on the base station is blinking, go to the handset and press Menu. From there navigate to Settings >> Registration >> Register
From the Subscribe Base menu screen, select the base station you would like to connect to and select Subscribe
Once completed, if your handset has successfully paired with the base station; you should receive a Handset Subscribed notification on your handset's screen.
Note: If you run into any issues pairing your handset to your base station, please refer to the DP752 user manual for additional information.

| Step 2 |
Logging into your base station |
|
To login to your base station's web configuration interface, you will need to retrieve the IP address of your base station. To do so, from your handset, press the Menu key and navigate to Status >> Base Status.
Next, open a web browser on your computer (Chrome, Firefox, Internet Explorer, Safari, etc) and enter the IP address that is displayed on your phones LCD screen into the address bar.
