All you'll need is a web browser including most cell phone web browsers as well. And, of course, it's free. What the Nerd Vittles' Phone Genie does is provide a web interface to the complete Asterisk Manager API. If you also happen to be using the Asterisk Management Portal or freePBX, then the sky's the limit since there are dozens of functions you can execute by sending web commands to manipulate data stored in Asterisk's internal database. These functions include call forwarding, call waiting, call tracing, do not disturb, and many more.
