Grandstream HT801 and HT802 ATA Setup Guide

Before you begin, ensure that you've created your extension in the My Account Portal, https://my.maxo.com.au/. To retrieve the details of an existing extension, or create a new extension, login to the My Account Portal and select SIP Trunks from the menu. If you're creating a new extension, click the Add Extension button, fill in the details and click Save. For additional information on creating an extension, please see Portal Guide - PBX Extensions and Sip Trunks

Find the extension number you're configuring, then click Edit.

Take note of the following fields, highlighted in the image below, as you'll need these to setup the device.

Register Username: This is the full username, not the short Ext No.
SIP Proxy: The server you'll be connecting to.
Re-Register Interval: Defines how often your device should check in.
Password: The extension's password

Note that if the extension is already configured on a device, you'll need to reconfigure, power down or factory reset the currently connected device before the required information will be displayed.

Accessing the ATA Configuration

The ATA is configured using a built in web interface on the device, which is accessed by entering the device's IP address into your web browser.

Before you can retrieve the IP of the ATA, you will need to ensure the following is completed:

A handset is connected to the Phone 1 port on the ATA
The power is connected to the ATA and the power icon is lit
An ethernet cable is connected from your router to the ATA, and the network

To retrieve the IP address, pickup the connected handset and dial ***

At the menu prompt enter 02 to hear the device's IP address, then enter this into you computer's web browser.

At the device's login page, enter the username and password for the device and login - by default these are both admin
