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. The 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 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.

Step 3 Release # and press 123456789*0#.
