Hi Is it possible to tap the numbers typed on the keyboard of a phone by tapping the line ?
It can be monitored by the caller id but if it's a blind number you won't see it. The only way is to capture the numbers typed by the sender on it's wire.
I'm stuch with a jerk who calls during the night and hides it's number but I'm pretty sure who does that.
That what I want to obtain as a result. The guy doens't make a noise when he calls. I suspect someone but the police doesn't open cases only on suspicions.
Turning off the ringer isn't a solution for me as I work by calls on a two hour advice. I need the phone 24 hours a day. People around me know to call only at certain hours except on real emergency.
It will be a massive logistical and financial challenge to actually tap his line. Call up a local PI in your area and make some enquiries. It's illegal without a court order.
