  • To begin, be sure the ATA is powered on and physically connected to your internet using and ethernet cord. If necessary, factory default the device before beginning to ensure no conflicting data will be left over. 
  • Verify the device has been added to your Simplifi Core portal by navigating to VoIP > Devices.
    • If it has not yet been added, contact a Simplifi representative or send an email to with the request to add a new device.  Be sure to include the MAC Address of the device. 
  • Plug an analog phone into port 1 on the ATA
  • After the unit is done booting and all the lights are green, pick up the handset and dial '***', then "02" at the menu prompt. This will give you the LAN IP address of the ATA. 
  • From a computer on the same network, log into the phone’s Web GUI:
    • Enter the phone LAN IP address in your computer's browser to access the phones GUI.
    • Factory default password is 'admin'
