摘要:
A telephone communication system is disclosed, in which a plurality of telephone stations based on an Internet protocol are connected to a LAN network to form an IP network including at least one constituent unit. Each constituent unit of said IP network, comprising: SIP server means based on a protocol defined for controlling the start, end and change of a session of an interactive communication; resource management server means for the control storage and delivery of station state databases of said plurality of telephone stations, and application server means. The SIP server means, the resource management server means and the application server means are connected to said LAN internet for offering required services to said plurality of telephone stations, so that information transmission among said plurality of telephone stations and each of said server means are performed on a packet-wise basis.
摘要:
To realize various additional service functions, which are available in a main device of a conventional button telephone system, in a voice over IP telephone. [Solving Means]A voice over IP telephone apparatus for carrying out voice communication adapted to an Internet Protocol (IP) through Internet is made to include a transmission/additional information generating and analyzing unit 12 for generating, at a transmitting side, additional information of service content to be added to transmission information related to a transmitter and a receiver as a destination, and for analyzing, at a receiving side, the additional information added to the transmission information transmitted by the transmitter to obtain the service content. The transmission/additional information generating and analyzing unit 12 is configured to check a response type for receiving, check a specified receiving communication type, and, when transmitting, generate transmission information specifying a response type at a receiving end and a communication type.
摘要:
To implement a key telephone system through an IP (Internet protocol) network, if real-time broadcast information is transmitted by multicast communications, restriction to prevent a rapid increase in network traffic is received, an additional special protocol is required, and it is hard to ensure the confidentiality of information. If real-time broadcast information is transmitted by unicast communications, transmission processing is centralized on a broadcast information transmission apparatus, the traffic becomes enormous, and a broad communication band and a high processing capability become necessary. Therefore, a transmission dedicated apparatus is provided between a broadcast information transmission apparatus and a terminal for distributing the transmission function and traffic. The broadcast information transmission apparatus needs only to manage the transmission dedicated apparatus. A plurality of terminals, etc., can be connected to the transmission dedicated apparatus. Further, a transmission dedicated apparatus can also be connected as a subordinate node to the transmission dedicated apparatus.
