Below are the three easiest options for setting your Handset to forward to an external number such as your Cell Phone:
Option 1: From the handset
To enable call forwarding: Menu>Features>Forward>Contact:"Dial Number">Enable
To disable call forwarding: Menu>Features>Forward>Disable
Option 2: From the Handset
*72"Dial Forward Number">Dial *it will state it is forwarding
*73 to turn off the Forwarding.
The problem with this is it does not display it is forwarding so the user has to remember to change it back
Option 3: From the Website
PBX>Ext>"Go into your Ext">Dial Plan>Add another Ring step with your external number>Place yourself in Do Not Disturb (DnD) when they want it to forward to the external number.
