Configuring the GXP1620/GXP1625 |
 |
The setup guide below is based the GXP1625, running on firmware revision 1.0.1.10; if you are running a different software version or are using the GXP1620 some menus/settings may be slightly different. These instructions are also based on using the GXP1625 in its factory default configuration, which obtains a dynamic IP address automatically from your router using DHCP. For information on configuring your GXP1625 with a static IP address, please refer to the GXP1625 user manual.
In this guide we will go through configuring the GXP1625 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 GXP1625 and our service. If you need additional assistance with any specific issue please let us know.
