1.) While at the phone in your office, press and hold one of the top 12 clear programmable keys just under the display for 2 seconds until it enters programming mode.
2.) Press the ESI-DEX button just under those on the left 5 times until it says “Feature Keys – Call Forward” and then press the now flashing programmable button to lock in that choice.
3.) Press the same programmable button 1 time and it will ask where to forward your calls to. Enter your number with a 9 first… so “9 1 419 555 5555” and then press #. The display will now read “CFWD Off-Premise” and all calls will be routed to your entered number.
4.) To disable this, press the same programmable button 1 time and press *.
