Configuring the GXP2170

These instructions are based on Grandstream GXP2170 firmware version 1.0.9.26; if you are running a different firmware version, some menus/settings may be different. These instructions are also based on using the GXP2170 in its factory default configuration, which obtains a dynamic IP address automatically from your router using DHCP. For information on configuring your GXP2170 with a static IP address, please refer to the GXP2170 user manual.

In this guide we will go through configuring the GXP2170 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 that you read 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 GXP2170 and our service. If you need additional assistance with any specific issue please let us know.
