Grandstream HT801 ATA Setup

Updated: 1/18/2025 3:49 AM

The Grandstream HT802 is an Analog Telephone Adapter (ATA) that allows analogue phones to be used with Vonage. A Factory Reset is needed when used with a prior service or moving to a different extension.

NOTES:

  • ATAs are not suitable for critical safety devices like fire alarms or elevators.
  • Device Setup Disclaimer: The setup instructions provided are based on best efforts. If you encounter any issues or need further assistance, we recommend contacting the device manufacturer directly. 
  • Connecting a fax machine to send and receive faxes is not supported. If you experience any issues with your fax machine, contact the manufacturer of your device for assistance with settings to work with VoIP. 
  • It is recommended that you set your fax machine speed to either 14.4K or 9600 Baud. Faxing requires the Vonage ATA to have a good quality network connection with sufficient bandwidth which includes no packet loss, low latency, and low jitter.

Factory Reset the Device
  1. Plug in and power on the ATA device.
  2. Locate the indented RESET button between the power and ethernet port.
  3. Use a paper clip or toothpick to press and hold the reset button for 10 seconds. Do not release the button until all 4 lights on the top of the ATA flash for 1-2 seconds.
Reset the Device from Web UI
This is an alternative method to reset the device and should only be used if the reset button does not work.
 
  1. Identify the ATA's IP address using one of these methods:
    • Access the DHCP client list on the user's router.
    • Download and run a network scanning tool, such as SoftPerfect Network Scanner on the user's PC.
    • Plug in an analogue phone to phone Port 1 of the ATA and press *** (three stars). After hearing the greeting, press 02 to hear the IP address being recited.
  2. Open a browser on a computer connected to your network.
  3. Enter the phone's IP address into the address bar of your browser to access the ATA's login page.
  4. Log in to the phone's web interface using the default password: admin 

    NOTE: Once your device is set up, your Vonage Business account number becomes the new password.
