Local and Centralized Conference Call Parameters

The following table lists available call management parameters.

Use the parameters in the following table to set up a conference type and the options available for each type of conference.

You can specify whether, when the host of a three-party local conference leaves the conference, the other two parties remain connected or disconnected. If you want the other two parties remain connected, the phone performs a transfer to keep the remaining parties connected. If the host of four-party local conference leaves the conference, all parties are disconnected and the conference call ends. If the host of a centralized conference leaves the conference, each remaining party remains connected. For more ways to manage conference calls, see Conference Management.
