[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...
