发明名称 Method for handling incoming calls directed to a virtual communication service subscriber via a guest PBX
摘要 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 first communication device. A call is placed to a second communication device using contact information provided by the virtual communication subscriber.

Upon connection to the second communication device, the incoming call is bridged with the call placed to the second communication device.
