A method of handling incoming calls directed to a virtual communication subscriber is disclosed. An incoming call intended for the virtual communication subscriber is received at a communication device. A call is placed to the communication device using contact information provided by the virtual communication subscriber. Extension information is provided to a SLS when the call is answered which corresponds to a communication line associated with the communication device. Upon connection to the communication device, the incoming call is bridged with the call placed to the communication device.
