DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an ISDN telephone that transmits and receives user information using low-bit encoded voice in a digital telephone that is connected to an ISDN network.

(Prior Art) ISDN network services provide various services that are not available in analog networks. Among them, there is a user-to-user information notification service that allows data up to 131 bytes to be exchanged from a signaling channel (D channel) when setting up or disconnecting a call. If you use this function, for example, when you make a call and the other party is absent and in the middle of a conversation, you can send a simple text-based message such as rXX, please call me later j as user information to the other party. I can do it.

[Problem to be solved by the invention]

In order to make effective use of such functions, it is necessary to have a function that allows the user to easily and quickly create and send the contents of the message they wish to send. Therefore, in the conventional method, a personal computer terminal or the like is connected to an ISDN digital telephone, and character-based messages are created and stored on the personal computer terminal side. In this method, it is necessary to always use the system in combination with a personal computer terminal, etc., and it becomes too large-scale as a system for utilizing user/user information.

Additionally, it is necessary to input characters using the computer keyboard during the call or immediately before disconnecting. Furthermore, even if the user-to-user information is displayed on the display of the receiving telephone, there is a drawback that the user-to-user information cannot be immediately viewed unless there is someone in a position where the display of the telephone can be seen.

In order to solve the above problems, this invention encodes a message input by voice at a low bit rate, and automatically transmits it from an ISDN communication control unit to an ISDN network via a user-user information transmission/reception unit. It is an object of the present invention to provide an ISND telephone in which analog voice is decoded by a voice encoding section of a receiving telephone and can be output from a speaker section or a transmitter/receiver section.
