Hi! A customers want to be able to run several telephone numbers @ night, and based on the response add the no into a table.

They want the computer to work out if the number is valid or not, ie wether the "this number is currently not available blah blah" message is played.

Is it possible to capture the sound into a waveform, and compare that to maybe another one?

Is this possible at all?

Any help extremley appreciated.
