Auto dialer components?

Seeking suggestions for components to use in the development of an
auto-dialer that can also play audio files. Ideally it will be able to tell
the difference (with reasonable accuracy) between people, fax machines,
answering machines and bad numbers.

Thanks!

What kind of hardware do you intend to use? How many phone lines will
the app need? Voice modems have never been very robust in the area of
call processing. For this type of application, you would be better off
using a dedicated telephony board from manufacturers such as Dialogic
(owned by Intel), Brooktrout, NaturalMicrosystems. You can find some
great prices on 2, 4 and more lines on E-Bay. Search for a D/21H which
is a 2 line board or D/41H which is 4 lines, but there are models that
can handle up to 3 T1's

You can also try vendors like Exceletel who have api's for driving
these telephony boards. For an api see this link:

Hi,

This capability depends completly on the hardware that you use as the
dialer. 99.9% of all modems cannot do what you want. A few can, with some
limitations.

In general, what you would want to use is purpose-built hardware. This
might be something that looks like an external modem, and that connects to a
single port, either serial or USB (about $150) and connects to a single
phone line. More complex hardware handles multiple phone lines, and usually
consists of a board or boards that plug into the PC backplane. The phone
lines might be analog, or even T1 (digital).

Software for these sorts of devices may be furnished with the hardware (with
an SDK), or might be purchased separately. At any rate, read: non-trivial,
but possible.
