To reboot a phone press and hold the below combination shown for your model until a tone is heard (about 3 seconds):

Do not do the following unless support has specifically asked you to factory reset your phone.  Doing this will cause your phone to erase all settings including the server information that is necessary to program the phone.  The phone will not be able to receive or place calls until it is re-programmed.  If you have entered numbers into the speed dial or directory menu they will all be deleted therefore you should make sure you have the information saved elsewhere or contact support before doing a reset to see if a backup option is available.  You will need to manually enter server information after the reset is complete.  If you don't know what information is needed contact support before performing the reset.

• IP 4000: 6, 8 and * dial pad keys

The phone will prompt you for the administrator password which by default is 456.  Support will provide you with an alternate password if needed.  Once reset the password will return to the default.
