Resetting and power cycling IP Telephones
Reset your IP Telephone when other troubleshooting suggestions do not correct the problem. Power cycle
with the approval of your System Administrator only when a reset does not resolve the problem.
Resetting an IP Telephone
This basic reset procedure should resolve most problems.
To reset your phone
1
Press Hold.
2
Using the dial pad, press the following keys in sequence: 73738#.
The display shows the message “Reset values? * = no # = yes.”

Choose one of the following from
Table 107, Resetting the IP Telephone,
4
Press # to restart the phone or * to terminate the restart and restore the phone to its previous state.
NOTE:
Any reset/restart of your phone may take a few minutes. At the switch, incoming IP
endpoint registration requests are rejected when processor occupancy is at or above 85%.
This event is recorded in the software events log. No alarms are generated for this event.
Power cycling an IP Telephone
Use the power cycle only if the basic or programmed reset procedure cannot be performed or does not
correct the problem.
To power cycle an IP Telephone
1
Unplug the phone and plug it back in.
The phone connection is re-established.
If power-cycling does not correct the problem, a more severe power cycle routine can be performed by
unplugging both the phone and the Ethernet cables. However, because this type of power cycle involves
reprogramming certain values, it should only be performed by your System Administrator.

Then...
Reset the phone without resetting
any assigned values
Press * (asterisk).
A confirmation tone sounds and the display prompts "Restart
phone? * = no # = yes."

assigned (programmed) values
(Use this option only if your phone
has programmed, static values)
Press # (the pound key)
The display shows the message “Resetting values” while your
IP Telephone resets its programmed values, such as the IP
address, to its default values, and re-establishes the connection
to the server. The display then prompts “Restart phone? * = no
# = yes.”
