Useful things to know about Cisco IP Phone software

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.
