Reset a ShoreTel phone handset to factory settingsYou may run in to a situation where you need to completely factory reset a Shoretel phone handset. This can be due to a handset being unresponsive or not talking to its headquarter server or local MGC, amongst other reasons like selling your handset!
To carry out a full factory reset you should take the following steps:
Press the MUTE button and then enter 772667# on the phone keypad
You need to then enter the default password of 1234#
The handset should now reset itself and display "Factory Test KPD Mode" on the screen
Enter 25327# on phone keypad to clear the handset settings
The handset will then display "Clearing Phone Data"
The handset will then restart and display "Factory Test KPD Mode"
You should then take out the power to the handset for 5-10 seconds, then plug the power back into it to fully power cycle the handset
If there is a firmware update to be applied, it will do it now; it not, it should then display "Available" on the handset.
