PURPOSE:To transfer an incoming call, expected to arrive at an extension, to another extension free of incoming connection when the incoming is brought under incoming connection control, by converting connection information equivalent to the extension into that equivalent to the transfer destination extension. CONSTITUTION:When opposite station C sends an incoming call to extension A, the number information of extension A is transferred by way of ICT, IR, MKR and NG. On receiving the number information from number group NG, incoming connection control discriminating converter RTFR discriminates whether or not it has the incoming connection specified and if so, the information is converted by the connection control information converter circuit inside RTFR into number information of extension B which is under no incoming connection control before being transferred again to NG. Then, NG reads out the fixed position information of extension B by the number information of this extension B and then transfers it to marker MKR, which makes a connection between extension B and opposite station C via incoming trunk ICT. |
