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. Extension information is provided to a guest PBX when the call is answered which corresponds to a communication line associated with the second communication device. Upon connection to the second communication device, the incoming call is bridged with the call placed to the second communication device.
