Abstract
In a communications network, a method and apparatus are disclosed for using a graphical user interface for telephony call control. A method is also disclosed for sending a datagram from a called party to a calling party. Call control of a call is diverted to a voice-mail system. The IP address of the caller is determined. The IP address of the caller is determined by either a search on a look-up table or from a voice over Internet call set up message. Call control information, or a datagram is sent to the caller. In the case of call control information, the caller inputs call control commands which are received by the voice mail system. The invention provides an easier method and apparatus to navigate voice-mail menus and reduces the problem of 'voice-mail jail'.
