Patent

CA 2637996

A method and dual-mode device for handing over an active call from the device's VoIP interface to its cellular interface. The active call is placed on hold and a second call is established from the VoIP interface to the cellular interface of the dual-mode device, wherein the second call includes a VoIP leg from the VoIP interface of the dual-mode device to a communications server. The remote device involved in the VoIP call is then instructed to initiate a new call to the communications server referencing the second call and causing the communications server to replace the VoIP leg of the second call with the new call, thereby joining the remote party to the second call connected to the cellular interface of the dual-mode device. The active call is then terminated.
