Patent

CA 2349310

The present invention provides a call merging service that enables communication devices to be joined to a call path as an extension telephone without any call interruption and hold time. Specifically, the present invention allows a call, placed to a subscriber who is already engaged in another call, to be merged into the subscriber's active call path. The predetermined Merging Allowed Calling Number (MACN) list of the called subscriber is checked to determine whether the incoming call is allowed to merge into the active call path. If the number associated with the incoming call is on the predetermined MACN list, then the incoming call is merged into the active call path. Otherwise, the incoming call is ignored and receives busy treatment.
