Cisco 7942 factory reset


When performing the factory reset procedure we are about to describe, it is important to keep in mind that the IP phone will lose all configuration files and phone applications. This means that it is necessary to have CallManager or CallManager Express setup so that the IP phone will be able to receive the new information (phone application and configuration) after the reset procedure is complete, otherwise it is most likely that the IP phone will not be usable until this information is loaded on to it.
This preparation also happens to be the procedure for upgrading a Cisco IP phone firmware.



Follow the steps below to successfully factory reset your Cisco 7942, 7962 IP phone:
  1. Unplug the power cable from the phone and then plug it back in. The phone begins its power up cycle.
  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.
  3. Release # and press 123456789*0#.
You can press a key twice in a row, but if you press the keys out of sequence, the factory reset will not take place.
After you press these keys, the line buttons on the phone flash red and the phone goes through the factory reset process.
Do not power down the phone until it completes the factory reset process and the main screen appears.

Mitel 5330 hookswitch will not release call and will not ring


Sounds like your hookswitch might be defective or in need of cleaning. With Cisco phones, you can disassemble the phone and clean the hookswitch circuit contact, and reassemble the phone and it often solves the problem. Not sure how easy this is to do with a Mitel handset but maybe worth looking into.

Cisco 7942G IP phone works in home office but it does not work in remote location


Hi J,
Typically corporate use VPN for these kind of critical service access. Check with your IP Tele/Network admin and get VPN access or may be OfficeExtend or any other solution employed. Corporate don't expose their UC servers on internet w/o security.

The very first password that comes with the phone new out of the box. I can't access the voice mail without a password.


The voicemail password is typically set on your PBX or Callmanager. The phone is only a registered extension, when you enter the VM password it is simply passing those digits to your PBX for validation.

Not working cisco 7962


For starters, have you obtained a Cisco Phone power supply for your 7962G? These phones require either a local 48V AC Adapter, or Power Over Ethernet, in order to power up.
