发明名称 Method of assisting a user placed on-hold
摘要 A method of assisting a user placed on-hold is provided. The user (20) is connected with a communication node (16) and a called party. The communication node (16) monitors the connection so that if the user (20) is placed on-hold, the user may instruct the node to call back at a call back number when the called party returns to the connection. The user (20) may also instruct the node (16) to leave a message for the called party. The user (20) then disconnects but the node (16) maintains the connection until the called party returns to prompt the node further or to receive the message left by the user.
