BizPhone Unregistered ATA

How to check registration

To confirm the handset is registered, check that the phone icons for each of your BizPhone lines are illuminated. A blinking icon simply indicates a busy line (blinking once per second) or voice mail (slow blinking).

BizPhone ATA lines registered example

Note: If your handset is registered but cannot receive calls, it may be DND (Do Not Disturb) mode. To turn this off, lift the handset and dial *79, then hang up. DND can be enabled again by dialling *78.

Troubleshooting Network Unavailable or Handset not registering

  1. Confirm that you can access the internet on a device that's connected to the same internet connection as your BizPhone handset.
  2. Make sure your handset is connected correctly to your modem or network switch.
  3. Try connecting the ATA to an alternate LAN port on your modem or network switch.
  4. Restart your modem.
  5. Restart your ATA by disconnecting the power and Ethernet cables for 10 seconds, then reconnect.
  6. Check your ATA is getting an IP address by lifting a connected handset and dialling *** to access the IVR menu. When you hear the “Enter the menu“ prompt, dial 02 and the IPv4 address will be announced.
  7. Is your network set up to deliver static IP addresses to connected devices? BizPhone hardware must be assigned an IP address via DHCP.
  8. To confirm your network allows access to the required server, Windows users should run an NSLookup test.
  9. Run the BizPhone connection test and make a note of the test result number from both the Speed and VoIP tests.
  10. If you’re still unable to make or receive calls, please email with your test result numbers and reference this troubleshooting article.
