Having phone issues? Here are step-by-step instructions on how to factory reset Polycom, Linksys, Cisco, Panasonic, Yealink, and Grandstream VoIP phones.

If you're going through phone trouble, there's almost always a way to fix it. Business VoIP desk phones, unlike most things in life, come with a reset option. You can solve just most phone registration issues by resetting your phone and re-registering it with your cloud phone system.

Besides general troubleshooting issues, you'll also have to reset your phone to configure brand new phones, reassign a phone to a new user, use it with a new phone service, or set it up with a new Internet connection.

The following post will outline how to reset Polycom, Linksys, Cisco, Panasonic, Yealink, and Grandstream phones to the factory default state. These are the most common brands our customers use. If you are having issues with a brand that's not listed here, you should ask your provider for more information.

We'll also show you how to get past the little kinks in each provider's reset process, and deal with issues such as lost admin passwords.

For Phones on the OnSIP Boot Server

If you're using OnSIP, and you want to factory reset one of your phones, you'll have to go into the OnSIP Admin Portal to reset the security key for that phone. This step happens prior to resetting the phone itself.

The phone's security key is a unique identifier that allows your phone to securely connect with the OnSIP boot server. Resetting the security key and resetting your phone are two distinct acts. However, you cannot reset the security key without resetting the phone. If you do this, your phone will not operate.

To reset the security key, click on the "Resources" tab in the Admin Portal. Select the phone you wish to reset. In the "Factory Reset" box, select "Reset Key".

Polycom: Factory Default & Password Reset

Reset Polycom phone to factory default

To reset a Polycom phone to factory defaults, press the "Menu" option on the phone. Navigate to "Settings" and then to "Advanced". A password prompt will appear. The default password is "456". See our instructions below if your admin credentials aren't working.

After you've entered the password, select the "Admin Settings" option and scroll down to "Reset to Default". There are three separate settings you're going to reset to restore the phone to factory default:

  1. Reset Local Configuration - This will reset the locally saved user settings.
  2. Reset Web Configuration - This will delete any information sent via the phone's WWW interface.
  3. Reset Device Settings - This will erase the phone's flash, including settings such as boot server, DHCP servers, syslog servers, and more.

From the current page, select "Reset Local". Then select "Reset Web". It will appear as if nothing is happening on the screen when you initiate these two resets. Continue on with the process. Then, select "Reset Device Settings". At this point, the phone will reboot and restore to its factory default.

What to do if the default "456" password doesn't work

If you've forgotten your admin password, or the default admin credentials aren't working, there's a way to manually reset the password so you can reset your Polycom phone.

First, find your MAC address on the back of the phone. Restart the phone by manually unplugging the device. Count to 10 and plug it back in. While the phone is powering, you'll need to press and hold certain keys simultaneously for 5-10 seconds. For details on which keys to press for your phone model, see our Knowledgebase article.

If you see "loading application" and no countdown on your screen, select "Cancel" and you'll be able to see the countdown process.

Next, you will be prompted to enter the admin password. Type in the phone's 12-character MAC address using the keypad on the phone. To switch between letters and numbers, press the "#" key or the key beneath the "A>a1" for Soundpoint IP phones, or press "mode" on VVX models.
