You can use a media-only phone (CS1K_IP or Device Adapter digital phone) or a CC phone (CS1K_IPCC) as a CTI controlled phone, regardless of the call center application that you use.
However, if you are using Call Center Elite, Avaya recommends that you use CC phones as CTI controlled phones. In an event when connection to the CTI application is lost, the agent can log in to the CC phone as a Call Center Elite agent and use the phone to perform call center-specific operations.
For more information about Call Center Elite-compatible phone types, see:
Use this procedure to enable an endpoint to be CTI controlled.
