How to Reformat a Phone That Was Previously Associated With Another Company

Overview

If a desk phone was previously linked to another EvoVoice account or a different company’s phone system, it may still contain old provisioning data. Before it can work with your EvoVoice account, you must reset it to factory settings and remove any old server configurations.

Steps to Reformat / Factory Reset a Phone

1. Identify the Phone Model

Check the model number printed on the back or underside of the phone. Each brand (Polycom, Yealink, Cisco, etc.) has its own reset method.

2. Perform a Factory Reset

Polycom

1. Power on the phone.

2. When the phone starts booting, press Cancel to enter the setup menu.

3. Go to Settings > Advanced (default admin password: 456).

4. Select Admin Settings > Reset to Defaults > Reset to Factory.

5. Confirm reset.

Yealink

1. Press the Menu button.

2. Go to Settings > Advanced Settings (default password: admin or 0000).

3. Select Reset to Factory and confirm.

Cisco

1. Press Settings.

2. Navigate to Admin Settings > Reset Settings.

3. Select Factory Reset.

Note: If you cannot log in because of an unknown admin password, you may need to perform a hardware reset (hold specific button combinations while powering on — see the manufacturer’s manual).

3. Remove Old Provisioning Server Details

Some phones may automatically reconnect to the previous company’s provisioning server even after a factory reset.

• Access the phone’s Web Interface via its IP address in a browser.

• Go to Provisioning Server or Auto-Provisioning.

• Clear the server URL and save the changes.

4. Provision the Phone for EvoVoice

Once the phone is reset and cleared:

1. Log into the EvoVoice Admin Portal.

2. Go to Devices and select Add Device.

3. Follow the EvoVoice provisioning instructions for your specific phone model.
