Whilst configuring my Cisco 7940 IP phone it’s been necessary to reset it a few times to load new configuration details. I started out by removing the power (pretty brutal, but effective), until I reached a point where I could telnet into the phone and issue a reset command.
Then I learned the reset codes for Cisco IP phones:
- For SIP firmware, press
*+6+settings - For SCCP firmware, key in
**#**.
Note that these are soft resets (like Ctrl+Alt+Del on a PC) – they do not return the phone to factory settings.
Finally, it may be useful to know that the default password for the phones is cisco.
The
**#**combination may need to be entered from the settings menu.Also, some SIP firmware (e.g. that for the 7911G) may use the
**#**combination to reset the device.
