Problems solved by technology

[0005] However, in the aforementioned system, the telephone terminals connected to different telephone switching devices from each other cause a mutual conversation state, so if they cause an additional state outside ECMA, that is, a hold state, or a hold transfer state related to each other, the telephone terminals cause no Necessary line hold state
As a result, limited lines become busy

[0021] FIG. 1 shows a schematic configuration diagram illustrating a first embodiment of a telephone system according to the present invention. The system includes an IP network INW. A plurality of telephone exchange equipment (PBX) EX1-EXn (n is a natural number) is connected to the IP network INW. The server SV is connected to the IP network INW.

[0022] Each terminal T11, T21, T31...Tn1 is respectively connected to a plurality of PBXs EX1-EXn. Each terminal T11, T21, T31...Tn1 uses an IP telephone terminal having a voice processing function and a media information processing function or a softphone realized by software on a personal computer. Further, the telephone exchange equipment EX1 is connected to the analog telephone network PNW.

[0023] Each telephone exchange apparatus EX1-EXn includes a call processing control unit 11, a function setting database 12, a CTI control unit 13 and a virtual I / O 14. Here, the telephone exchange equipment EX1 will be described as a...

[0054] 6A and 6B show a CSTA call model according to a second embodiment of the present invention.

[0055] FIG. 6A shows such a state: the terminal T11 (N1D1) and the terminal T21 (N2D4) are in a talking state, the terminal T11 becomes a hold state, and then the terminal T21 becomes a hold transfer state.

[0056] In said case, since the system becomes a state in which the terminal T11 becomes the hold state or the hold transfer state and the terminal T21 becomes the hold transfer state, the hold transfer state among the terminals N2D4-N2C1 is returned to the initial state which becomes the state shown in Fig. 6B.

[0057] Fig. 7 is a view illustrating the sequence of CSTA models. Here, the behavior of each control unit is omitted, and CSTA messages and events are described.

[0058] Fig. 7 shows the sequence according to the following preconditions: after the terminal T21 performs a hold transfer operation in case the terminals T11, T21 are in a call state via the IP netwo...

Abstract

According to one embodiment, a telephone system includes a plurality of telephone exchange apparatuses (EX1 to EXn) which execute exchange processing among a plurality of telephone terminals (T11 to Tn1) and a server apparatus (SV) which is connected to the plurality of telephone exchange apparatuses (EX1 to EXn) via transmission paths (INW), receives a call information event to specify a plurality of telephone terminals (T11 to Tn1) to be call-connected, and executes a computer supported telephony application with prescribed standards regarding call state management of the plurality of telephone terminals (T11 to Tn1), wherein the server apparatus (SV) includes a controller (22) which returns a telephone terminal which has become an extra state of the standards to a state in the standards, when the sate in the standards changes into the extra state of the standards in a state in which call connections among a plurality of telephone terminals (T11, T21) connected to telephone exchange apparatuses (EX1, EX2) different from one another.

Description

technical field [0001] Embodiments of the present invention relate to a telephone system and a server device performing operation management of a plurality of telephone switching devices connected to each other via the IP network by using the server device via an Internet Protocol (IP) network . Background technique [0002] In recent years, an IP telephone system that interactively transmits and receives images and voice as packet data in real time via an IP network has come into widespread use. The IP telephone system can perform inter-extension communication and outside line origination and termination for each telephone switching device to be connected to the IP network, and can also perform inter-extension communication and outside line origination between telephone switching devices via the IP network and terminated. [0003] Meanwhile, also in the IP telephone system, Computer Telephony Integration (CTI) for realizing a high-end system may be employed. CTI connects...
