The Parallax Basic Stamp Manual (Parallaxinc.com) has a telephone line interface on page 361. DTMF.src was available on the Parallax bbs. I can email it to you. I believe there was also a DTMF "in" program. Simple? Of course if you don't mind taking up to 20 seconds to dial a number you could use pulse dialing. All you need is a relay driven by the PIC and a loop current resistor. If this isn't going to be FCC approved, you could maybe simplify the telephone line interface just so the PIC does something to the line that can be detected as data at the other end (PIC driven optocoupler and higher value resistor across line).
