HOW would I go about extracting shielded DLE responses that are returned from the modem, such as DTMF tones,  from within program code? HOW do you select WHICH voice file you want to send using the #VTX command?

Hi cress,
        Well, there is a hard way and an easy way .
        1) Hard way :
        Using AT#V or AT+V commands requires lot of code
        and sweat . You have to figure out which compression
        algorithm to use like ADPCM or PCM etc. Which is
        possible, but it's a pain .
        2) Easy Way : Use TAPI , using TAPI is not so easy
        but much better than using AT#V commands .
        TAPI in Windows 95/NT4.0 requires to have Unimodem/V
        driver installed on your machine (which can be         downloaded from Microsoft Web site for free).
        Now comes another question, which language to use
        to program TAPI. If you wish to use VC++ , there
        a lot of examples provided by MS for DTMF tones, playing
        an WAV file using WAV wrappers etc. in MSDN .
        If you wish to use VB , then options are endless
        there TAPI OCX controls available from "free" to $500.
       
        Let me know if you need more information/files .

Hi Cress,
        Sorry for the delay .
        Here is the info you requested .
        1) The Best Tapi control I used will be Visual Voice for
           TAPI from Artisoft . Which costs you about $495
           But it relieves most of the headaches associated
           with TAPI or AT#V commands
        2) The Second best and a FREE solution is
           from Creative Labs (the SoundBlaster /PhoneBlaster    
           guys). But you need to sign an agreement with
           Creative Labs to access thier software library .
           Which is I consider THE BEST . They have exactly
           what you are looking for i.e C/C++ sample code for
           AT+V or AT#V commands . Which might help you .
       
       3) Now the intermediate solution :
           There is a book in the market with title
           "SAPI, MAPI and TAPI" sells for about $60 with a
           CDROM for Sample code and OCX files .
           the author has published a TAPILINE.OCX control
           (FREE) with which he developed several examples .
           
          I hope it helps you .
     
           Just curious : .GSM file sounds familiar
           what are you upto ? ( if you don't mind)

          Bye, Have a nice day

Andaluri, Thanks for your response. However, because I am based in Durban, South Africa, and have a project deadline in less than two weeks, it's going to be difficult for me to get hold of the TAPI software. Luckily for me though, after a lot of struggling, I have developed my own routines in VB5 that can play GSM Voice files through the Voice Modem, as well as a routine that can retrieve DTMF digits. I'm sure your links would have proved helpful, so thank you anyway!

What am I up to? I am creating a "Remote Booking System" whereby someone can dial into a Voice Modem and book an appointment in a particular timeslot on a day of his choice. I am using Visual Basic 5.0 to interface my USRobotics Sportster Voice to an Access 97 database. This system will also be accessible via the Internet, where I am using Active Server Pages to interface the Web Browser with the same database. At present, I could say that I am 80% complete.

I'll post a comment here when it's complete, giving an address where you can download the program from, if you are interested?

Andaluri...

I have recently completed my project, called "The Remote Booking System". If you want to download it for free, it can be found at http://users.iafrica.co,/c/cr/cress.
