Hi, the Picbasic Pro compiler has built-in commands that generate DTMF tones; makes your coding real easy. Look upo their site, they even have a demo version that can compile small programs for free. Welcome to microEngineering Labs

You'll also need a 600 ohm transformer for both engaging the line and isolation.
