This is a well-documented solution for storing unlimited caller ID phone numbers. The site contains schematics and the software needed to decode and store the data.
Some time ago, I subscribed to the Caller Id service to know who is calling me without being required to pick-up the phone. Unfortunately, my basic caller id display could not memorize enough numbers, and I had to write them manually in a computer to keep them. That’s why I decided to find a way to log the calling numbers directly to my computer.

Easier way:
1) Get a USB modem that supports caller ID.
2) Attach modem to a Unix/BSD/Linux system.
3) Run the “cu” program. (Eg. cu -l /dev/cu.usbmodem)
4) Activate the caller ID with “AT+VCID=1″ or similar.
5) Write a program to substitute for “cu” for custom actions.
Here’s the software:

Why couldn’t you plug the phone line into the modem on the computer and out of the modem into the computer, and have software handle decoding it?
