reboot. Reasons for this include accepting a

and Volume keys (highlighted above) for
more than 3 seconds. The reboot process will
begin and is complete when the idle display is
shown.

IP 500 SIP telephone:
• Check that the display is illuminated.
• Make sure the LAN cable is inserted
properly at the rear of the telephone
(try unplugging and re-inserting the

the switch is supplying power to
the telephone (contact your System
Administrator).
In the case of problems, it may be possible to restore normal operation of your
telephone without rebooting. Contact your System Administrator before attempting
to reboot the telephone.

Troubleshooting
Verify if dial tone is present on any other
audio paths:

dial tone is present on these other
paths.
• If dial tone exists on one of these,
connect a different handset or
headset to isolate the problem.
