voice modem..

[Yanco]

Hello all,

(I'm not sure if I am in correct thread so if not, please move it to the correct one, thanks.)

I have a following problem.
I am to create a system that will be able to make phone calls over voice modem. User will have microphone and speakers pluged into it and through application (which i am to make) dials a random number form our database. The application has to dial the number and then intercept "all" events. Such as hang up, busy line etc.
Times of the events are then stored into the database for further analysis..
Modem will not be used for connecting to internet only for voice calls.
My questions are:

1) What kind of modem to use (I can buy almost any available at the market with price up to $70, the cheaper the better of coruse ;) ) I would appreciate direct link to a particular model of modem(s) of particular manufacturer if possible :) Or in other words what voice modems you have good experience with from programmers point of view?

2) I've read something about TAPI. Can I use it for this kind of problem to intercept those events etc?

3) "Further reading" If you have any suggested web-sites (articles) regarding modems or programing with TAPI, that I should pay visit to, I would very appreciate it. So far I found only few http://www.modemsite.com, http://en.wikipedia.org/wiki/Modem, http://modems.rosenet.net/

4) This is not that important but, Is there a way to record the call ?

Thank you very much in advance.

Yes, you can record from a specific input by clicking the check-box in record volume control. If you want to record everything you have to select "Mono-Mix" or "Stereo-Mix".
For information on recording with Windows API look here (http://windowssdk.msdn.microsoft.com/library/default.asp?url=/library/en-us/Multimed/htm/_win32_waveinopen.asp).

Thank you very much philkr.
I really appreciate it. :thumb:

So remains the first question.. What voice modem would you recommend? I prefer quality over price. But don't need anything too fancy..

Thank you again.
