I am new here. After lurking around for quite sometime, I finaly had the courage to post.
Guys, I am looking for a circuit that will time a phone call. It should automatically go off once an outside the connection is established and should retain the number of minutes spent at the end of the connection, until a reset is made. There should be no call allowed until the counter has been reset.
My goal is to track my telephone usage because my line is metered and I think my provider is cheating on the bill.
It will not do you a great deal of good with your phone company.
They will just say that their measuring equipment is much more accurate than yours. I would suggest using your PC as a phone dialer there should be software around that has logs. This way you have the number called, time of call and duration.
I need something similar to WildSwan but for a project i'm working on. I want to use it to open a prepaid phone booth so i can track the time they spend on the phone. I want the same things he wants.
