There was a point in 2005 when it was important to me to know when someone called my house so I could call my answering machine and Get the message. I created CIDTracker so when a call came in I could detect it with my Mac and email myself the details. Then I could call right when the message came in and I could stop checking every hour.
Features of current release v1.2 (build 57)
* Can decode CID information from a modem attached to your Macintosh
* Can receive CID info from CIDTrackerX operating in server mode on a networked computer
* Can receive CID info from a networked computer running a Caller ID server supporting the Network Caller ID (NCID) protocol
* Can receive CID info from CallerID Sentry or a program that supports that protocol like the ACID Program for the 3Com Audrey (which has a CID compatible modem built in).
* Can receive CID info from a Yet Another Caller ID (YAC) compatible server.
