Explanation
Cisco IP phones have specific key sequences to perform a factory reset, usually involving holding down certain keys during boot.
The correct method to reset a Cisco IP phone to factory settings is to dial a specific key sequence on the phone during the boot process. This involves disconnecting power, reconnecting it, and then entering a designated sequence of keys, commonly starting with holding the “#” key and then dialing “123456789*0#”. This procedure erases all user and network configuration, restoring the phone to its original factory state.
Detailed Explanation:
- Disconnect power from the phone (unplug Ethernet or power adapter).
- Press and hold the “#” key while reconnecting the power.
- Wait for the indicator lights to begin flashing, then release the “#” key.
- Enter the reset sequence: 123456789*0#.
- Follow any on-screen prompts to confirm the reset or retain network settings.
- The phone will reboot and restore factory defaults.
This process is standardized across most Cisco IP phone models, though some newer models may also allow a factory reset through the phone’s menu under device administration settings.
This method ensures a complete factory reset, clearing all settings and preparing the phone for redeployment or troubleshooting.
