COS 245, 208 for console, trunks. Disable COS option 200. System option 21 enable. Program FAC 03 Call fwd all calls. Form 30, Device Interconnection table, connect devices together. Program form 31 for destination number.I usually program an unused extension for call forward in form 9 to the speed dial bin. Make the abbreviated speed dial access code to something easy (8)(99) being the bin number storing the external call).(remember the "9" before the outside number.
