TAPI Auto dialer

Hello, I need someone with considerable C++, TAPI and Win32 skills to write the following multithreaded windows application: 1. Dial a phone number as fast as the hardware allows on all existing tapi lines. Use one dialing thread per line. 2. Eventually someone (a human being or a answering machine) will pick up the phone. As soon as you receive ringback dialtone, or voice level signal (make sure it is not a busy tone!) on one of the lines, do the following: -Stop all dialing. -Dial a cell phone number on one of the lines. -Forward all data from the answered line to the cell phone line. This should be a very easy project for someone skilled in TAPI. If interested, please provide samples with relevant TAPI experience and be prepared to answer some technical questions :-) The project MUST use TAPI 2.x for compatibility reasons. The application will eventually run on Dialogic, but I want it to also run on regular voice modems. So, you will have to assume it works with a regular Unimodem driver. Among many other unpleasant things that means: 1) You may get LINECALLSTATE_CONNECTED before, or after the voice trunk actually gets connected. 2) You get LINECALLSTATE_CONNECTED even if the line is actually busy. 3) You may never get LINE_BUSY notification so don't rely on it. 4) Tone detectors ala LINE_MONITORTONE are also not reliable, the only thing that works ok is LINE_MONITORDIGITS. Be prepared to do some frequency analysis on your own, FFT (as in Fast Fourier Transformation) is the keyword here. For this reason, DSP background is a huge plus. If you are not intimidated by the above obstacles (actually there are more, but I don't want to scare you) go ahead and place a bid. I am a professional software developer so let's respect each other's time. Only qualified people need apply.
