发明名称 METHOD FOR NETWORK CALL HOLD AND PICK-UP
摘要 A method for picking up a call by a second communication device after the call has been placed on hold by a first communication device regardless of the communication device type or whether it is within a closed network is achieved by detecting, by a server associated with the first communication device, that a call has been placed on hold by the first communication device and subsequently suspending the call. Next, the server associated with the first communication device waits for a directive call pick-up message, which may be provided by the first communication device or from a second communication device directly or via a server associated with the second communication device. When the server associated with the first communication device receives the directive pick-up message, it communicates with the server associated with the second communication device. Such a communication establishes a communication link between the servers such that the call may be picked up by the second communication device.
