发明名称 Message length reporting system for telephone communication system
摘要 A voice mail message system detects the length of each message and provides an indication of the length to a user together with other message information when messages are requested. The indication of message length may be a qualitative one in which the number of short, medium and long messages is indicated to the user. In addition, if a user interrupts a message as it is being played back, the user is informed of the remaining length of the message.
