One Talk CP920 IP Conference Phone - Activate / Set Up Device

Follow these steps to perform initial activation on your One Talk CP920 IP conference phone.
  • Activation requires a valid US address for E911 functionality.
  • Wi-Fi Calls always originate in the U.S., even when you're outside of the U.S.
    • Calls to U.S. numbers are not billed (except for 411 or other premium calls).
    • Calls to international numbers are billed according to your international long distance plan.
  • A soft reset is needed on the desk phone when a new endpoint is added to the One Talk MDN.
  • If the desk phone only boots partially and displays "Invalid security certificate", it must be replaced via the CLNR/WFG exchange process. The desk phone will not work under this condition.
  1. Connect the power and wired network.
    You have two options for network and power connections. Your system administrator will advise you which one to use.
    You can also connect to a Wi-Fi network after startup. Refer to Step 3 for more information.
