On the switchboard:
- Lift handset
- dial 7102 ( this is all call forward)
- dial 0 followed by a valid extension ( where the calls will be forwarded to)
If the phone beeps 3 times, then the firmware is out of date.
If it was successful all calls will now be forwarded to the extension that was
entered. This means your firmware is up to date.
NOTE!
To cancel the forwarding lift handset and dial 7100
