This is very difficult to do from a cell phone. You would need a receiver
that can ID your code set from the repeater. This would be like the front
end of a cell phone. Then there would be the decoding which is proprietary
to the phone company.
Your phone company should be able to provide you with detailed billing. All
the modern cell phones can display and remember up to at least 30 previous
calls. You should be able to configure this to show the number of calls,
dates, times in and out, and total times of each of the calls. Therefore
there is no real need for what you want to do.
Also, many phone companies offer a telephone traffic fax-back service. In
our place we get a fax every for 30 calls from and to, for any of our phone
lines and cell phones as well. At the end of the day, or a few times a day,
we get a fax from the tele company of all the tele traffic, and details of
each call. We get the number dialled, time and date of the call, duration of
the call, and if it is a received call we get the number of the location
that dialled us. This can be used as a legal record, and also to keep track
of the telephone companies billing at the end of each month. We keep these
records for 3 years.

I am looking for a circuit that will count the number of incoming phone
calls. It should use two 7-segment LED displays to display the number of
calls that have come in.
