へ転送させることができないという問題があった。As described above, in the conventional call transfer method, the call transfer destination is fixed regardless of the terminal type of the calling side. Therefore, for example, the calling side is called an important terminal or a general terminal. There is a problem that it cannot be divided and transferred to different terminals depending on each terminal.

nt: DTE) addresses 100-01 and 100-02
Terminals A and B are connected via terminal lines 101 and 102, respectively, and terminals C to E via terminal lines 201, 202 and 203 of DTE addresses 200-01, 200-02 and 200-03 to the packet switch 200. Are connected respectively. The packet switches 100 and 200 are connected by a trunk line 400, and the packet switch 20 on the receiving side is connected.
0 has a memory 300 for storing an incoming call destination corresponding to the calling DTE address. In FIG. 1B, the transfer destination corresponding to the calling side DTE address is shown in the memory corresponding to the terminal line 201 of the DTE address 200-01.

The operation when a call is made to the terminal C of the terminal line 201 of the DTE address 200-01 connected to the packet switch 200 via 01 and the relay line 400 will be described.

01 on the memory 300 of the calling side DTE address 100-
By identifying that the transfer destination corresponding to 01 is the DTE address 200-02, the transfer destination is transferred to the terminal D having the DTE address 200-02.
