Abstract

PURPOSE:To avoid useless talking by allowing a caller to recognize whether or not a called party is an automatic answering telephone set before talking and allowing the caller to select whether or not the caller is to make a call depending on the recognition. CONSTITUTION:The system receives an automatic answering telephone set indication signal with a specific frequency representing the presence of an automatic answering telephone set sent from the automatic answering telephone set of a called party 11 so as to detect it that the called party 11 is the automatic answering telephone set. Or the called party 11 sends a special audible tone as the automatic answering telephone set indication tone representing it that the called party 11 is the automatic answering telephone set to the caller 1. When the caller 1 desires to make a request of talking to the called party (automatic answering telephone set) 11, the caller dials a special number as a talking request signal to enable the talking with the called party (automatic answering telephone set) 11. Since the caller 1 recognizes it before the actual talking that called party is the automatic answering telephone set and can select whether or not the talking is to be made, useless talking is avoided.

The figure shows one embodiment of the present invention, where 1 is a caller, 2 (2
' ) is the network, 3 is the trunk that receives the called party number dialed by the caller, 4 is the trunk that receives the call request signal to the answering machine dialed by the caller, and 5 is returned by the other station. A trunk that receives an answering machine display tone indicating that the called party is on answering machine, 6 and 7 are talking trunks, 8 is a trunk that detects that the called party is on answering machine, 9 is a trunk that detects that the called party is on answering machine. A trunk that sends an answering machine display to the calling party indicating that it is a telephone call;
10 (10') is network 2 (2' L and 3
A control device controls the trunks 9 to 9, and 11 indicates the called party (answering machine). First, when calling party 1 goes off-hook to make a call to called party 11, network 2's path ■
is formed, the called party number dialed by the calling party is received on the trunk 3, and the control device 10 opens the path (■) of the network 2 for the called party to come out, the path (2) is formed, and the trunk 5 At the same time as it prepares to receive the answering machine display tone sent from the caller, it also forms a path (3), sends an outgoing signal to the trunk 7 of the station that accommodates the called party 11, and sends a call signal to the control device of the station that accommodates the called party. When 10' receives an outgoing signal from trunk 7, a path (■) of network 2' of the called party accommodation station is formed.
The trunk 8 receives an answering machine display signal sent from the answering machine of the called party, and when it detects that the called party is using the answering machine, the control device 10' changes the path of the network 2' of the called party receiving station. , and form a path ■. Trunk 9 sends an answering machine display tone to caller 1, and the tone is received by trunk 5. When the trunk 5 receives the answering machine display tone, the control device 10 forms a path 2 of the network 2, and the trunk 4 prepares for the call request signal sent from the calling party 1. hear the sound,
When the calling party 1 learns that the called party 11 has an answering machine and wishes to refuse the call to the answering machine, the caller 1 goes on-hook at that point and performs call termination processing. If the caller 1 wishes to make a call to the answering machine, he/she dials a special number (for example, *1) as a call request signal. The call request signal is received by the trunk 4, and the control device 10 opens the path (2) of the network 2 and sends a re-transmission signal to the receiving station of the called party. The re-transmission signal sent from the calling party is received by the trunk 7, and the control device 10' of the called party receiving station opens the path ■ of the station's network 2', forms a path ■, and returns the called party 11 to the called party. You can now make calls to (answering machine).
