I haven't had my Obi long, and don't remember ever setting up call forwarding. Someone who was trying to call my Obi number instead was forwarded to my cell phone. This person has both the obi (home) and my cell phone number programmed into their phone. When I call the Obi number it works fine and doesn't forward my call. I've looked online and it looks like I don't have any call forwarding set up. Thanks!
