3.2.4 Three-Way Conference, Local or Centralized

Local or centralized conferences2 are supported. The phone can conference together the local user with the remote parties of two independent calls by using the phone’s local audio processing resources for the audio bridging. For a local conference there is no dependency on network signaling.

The phone also supports centralized conferences for which external resources are used such as a conference bridge. This relies on network signaling.

Central	Configuration file:	Specify which type of conference to establish and the
	sip.cfg	address of the centralized conference resource.
