I am working with a customer that has a IP Office 500 V2 at 9.0.5, Basic Edition. I've never programmed forwarding on a Basic system before. I've read that I have to set up speed dials, then set a forward button on the phone to point to the speed dial. This extension has remote call forwarding on. The customer wants to have calls coming to his extension forward to his cell phone when he's out of the office. How do I set up a speed dial on Basic mode?
