I would like to write an Windows XP application to provide a specialized GUI for the physically disabled so they can use their PC to dial and talk on the phone. Is Express Talk and the NCH Unified API a way to do this?
1) Can the "Unified NCH Software API" be used on Express Talk to control it via .Net calls from my application?
2) If answer to question 1 it "yes" where can I find relevant documentation on the Express Talk API?
Ideally, I would like to be able to:
1) make and receive PSTN phone calls.
2) create PC-PC conference calls with 5 to 10 PC's
3) mix audio from a text-to-speech engine with the microphone audio.
Any suggestions on how to achieve this functionality would be greatly appreciated.
