Interface for telephones & Java?

Trippy idea? Does this mean good or bad? Should I pursue this idea, you think it would be worth it for a final year computer science project?

I have an idea for my final year project. Basically I would like to write a program that will log all outgoing calls from a normal telephone.

To be blunt, you can''t. Even if you contrive a solution, it won''t be able to provide any more information than an itemised bill.

Um, isn''t a log of outgoing calls the same as an itemized bill?
With the windows TAPI, I''m pretty sure you can record too.

The bloody expensive part, is you need a way to connect every phone to the device, or need a device for every phone. (i.e. Java is not the right tool for this job). Java fits in on the client-end, for writing a user interface to read information out of, say, a pbx system (that already keeps track of outgoing call information).

Here''s the Java api for it - heh, it''s just a spec. It looks like you have to buy an implementation (or write your own). Perhaps someone has written a JTAPI provider that uses TAPI. Then you just need a Win32 machine for each phone

An alternative is to buy a DTMF algorithm, and build a small embedded device. A TI chip that could do the job cost about $20 (less in bluk). Have a look here
