Embodiment Construction

[0037] Embodiments of the present invention will be described below with reference to the drawings. In the following description, the same components are marked with the same reference symbols. Its name and function are also the same. Therefore, its detailed description will not be repeated.

[0038] Fig. 1 schematically shows the configuration of an IP telephone system according to the present invention. In this IP telephone system, IP telephone terminals 1 and 2 and a SIP (Session Initiation Protocol) server 3 are connected through a network 5 . In this IP telephone system, VoIP (Voice over Internet Protocol, voice over IP) technology is used.

[0039]The IP telephone terminal 1 includes a control unit 10 for controlling the overall operation of the IP telephone terminal 1 . Also, the IP telephone terminal 1 includes: an operation unit 16 operable by a user for inputting information to the IP telephone terminal 1; a storage unit 17 for storing various data and programs; ...

Abstract

The invention relates to IP telephone terminal, IP telephone system and recording medium. The IP telephone terminal outputs a call request for communication with a prescribed terminal and, if it is determined that connection failed, records the input voice. Thereafter, the IP telephone terminal determines that the prescribed telephone terminal has reached a state connectable through IP network, outputs a call request for communication with the prescribed terminal and if connection is determined to be established, transmits the recorded voice to the prescribed terminal.

Description

technical field [0001] The present invention relates to an IP (Internet Protocol) telephone terminal and an IP telephone system, and more particularly, to an IP telephone terminal accepting message records, an IP telephone system including such an IP telephone terminal and a server, and to a recording medium. Background technique [0002] With the widespread use of Internet devices recently, IP telephone systems that provide telephone services using IP networks are also widely used. In an IP telephone system, unlike a landline telephone, a telephone terminal is not always connected to a line. Specifically, a landline phone is always connected to a phone line, whereas in an IP phone system, a phone terminal is not always registered with a server. [0003] The reason why the telephone terminal is not always registered with the server in the IP telephone system is that the connection status of the telephone terminal to the network changes according to power-on / off of the telep...
