What's the decent, cheap, way to get both talk and listen sides of a phone call on a POTS line into the MIC-in on a PC in a non-intrusive way?
For extra credit, the ability to detect ring and Off-hook from software (somebidy elses's problem) running on the PC would be nice.
Software code to listen to the DTMF tones and spit out the digits dialed would be great.
Ideas ?
