PyGCID - A CallerID application written in Python. 

PyGCID (That's (Py)thon G(tk) (C)aller (ID)) will read the numbers of
incoming calls from an external program that communicates with some
kind of telephone hardware. It will store the number in a small
database and display a popup window with the number and time, together
with information about the number that you insert into the database.

It can also dial the numbers in the database, using an external
program such as dtmfdial.

For installation instructions, refer to the INSTALL file included in
the distribution. 

The latest version of PyGCID is available from
