Resetting or Restoring the Cisco Unified IP Phone
Performing a Factory Reset
When you perform a factory reset of the Cisco Unified IP Phone, the following information is erased or
reset to its default value:
• CTL file—Erased
• LSC—Erased
• User configuration settings—Reset to default values
• Network configuration settings—Reset to default values
• Call histories—Erased
• Locale information—Reset to default values
• Phone application—Erased (phone recovers by loading the appropriate default load file
(term62.default.loads, term61.default.loads, term42.default.loads, or term41.defaults.loads)
depending on the phone model)
Before you perform a factory reset, ensure that the following conditions are met:
• The phone must be on a DHCP-enabled network.
• A valid TFTP server must be set in DHCP option 150 or option 66 on the DHCP server.
• The default load file for your phone model and the files specified in that file should be available on
the TFTP server that is specified by the DHCP packet.
To perform a factory reset of a phone, perform the following steps:
Procedure
Step 1 Unplug the power cable from the phone and then plug it back in.
The phone begins its power-up cycle.
Step 2 While the phone is powering up, and before the Speaker button flashes on and off,
press and hold #.
Continue to hold # until each line button flashes on and off in sequence in amber.
