How to Reset Your Desk Phone Adapter (ATA)

If your Staff phone and client phone is not working or has lost its connection, a simple physical reset can often resolve the issue. This process, known as "power cycling," restarts the Analog Telephone Adapter (ATA) and allows it to reconnect to the network.

What is an ATA?

The ATA is a small electronic box that connects your traditional desk phone to the internet. It acts as a bridge, allowing your phone to communicate with our digital phone system.

Step 1: Locate Your ATA

The ATA is typically found near your desk or in a common tech area. It is a small rectangular device with several cables plugged into the back.


Location Example:Hudson House

Client ATA: on top of the network rack behind the door in the main office as seen in the picture.

The Staff ATA will be located next to the printer in the same office as seen below:

Step 2: Identify the Power Cable

On the back of the device, you will see several ports. Look for the power cable, which is usually the smallest round plug (often labeled "DC" or "Power").


Step 3: Unplug and Wait

  1. Gently pull the power cable out of the back of the ATA.

  2. Wait for at least 30 seconds. This ensures all residual power has left the device, allowing for a clean restart.

Step 4: Reconnect the Power

  1. Plug the power cable back into the ATA.

  2. Ensure the cable is pushed in firmly.

Step 5: Wait for Re-Configuration

Once plugged back in, the ATA will begin its startup sequence. You will see lights on the front of the device start to flicker.


  • Wait for Connection: It may take several minutes for the device to "pick up" its configuration from the server.

  • Verification: Once the lights remain steady (usually green), test your phone line to ensure the dial tone has returned.
