[Dan Sikorsky]

How can you dial a phone number, wait for the receiver to pick up, and play
a .wav file if the call was picked up?

Hello

I donot have much information of it , but as far as i know you have to work
on TAPI (Telephony API).

Unfortunately, voice modems are not very good at determining the
progress of a call. They can detect a busy signal or a no answer, but
if there is a connection, they are not very good at determining if the
call was answered by a person or by an answering machine.

For robust telephony apps, you should use a dedicated telephony board
from makers like Dialogic (owned by Intel), Brooktrout, or Natural
Micro-systems. These boards typically can provide line densities from
2 lines up to several T1's. You can use ISDN PRI or VOIP with many of
them. It just depends on what you want to do.

There are api's for working with this type of hardware available. NCT
soft has an inexpensive library for working with Dialogic (Intel) brand
hardware, there are other vendors as well.
