help telephony application

[prodigy]

Dear all,
have tried searching many sites but of no help. hope this is the right place to ask my query.

I would like to develop an application with the help of which I can make phone calls through my PC (windows 2000) and record calls as required. I have come to know that TAPI is the technology to use. However how do i start and what are the requisites.

any help is appreciated.

Thanks and regards,
Prodigy.

There's far more to something like that than just using TAPI. TAPI will allow you to control the basics -- a modem or telnet emulation, for example. You're not considering the bigger picture, which is that you're essentially trying to figure out how to write VoIP software like Skype.

You're also not considering the audio part of things, which would have nothing to do with TAPI. Basically, you'd have to figure out how to translate the zeroes and ones into audio, similar to MP3 compression, but lesser quality. You'd want to see if there are programming interfaces for GSM, DSM Group TrueSpeech, or Lemout & Hauspie. Those are compressors used in Ventrilo.

Finally, this is not something you'd write in Access. You'd do it in the language of your choice (VB, C#, C++, etc.), but not in a language connected to an application (VBA and others). A telephony program has nothing to do with databases, spreadsheets, etc. -- it's completely stand alone. I've not investigated how to write an application like what you're describing, but I will say experience tells me that it's something where you'd better have a lot of experience programming in the first place.

dear moniker,
thanks for your time and answer to my query. i could understand from your reply that its not only Tapi but more than that. i know languages like vb, c#, c++ also.

if you could guide me through on what should be the next step that i must take in order to accomplish the task.

i have also come to know that one can record phone calls to PC using voice modem. but i dont know on how to write code to use it or what tools i can avail in order to get my things done.
