Note: Accommodation of devices not purchased from and originally provisioned for service by 8x8 is best-effort. These devices are not guaranteed to be supported on 8x8 service. 


Overview

Before attempting to provision a third-party phone for 8x8 service, you should check your device for a valid, factory-issued device certificate. You will then be able to provision your device for 8x8 service. The certificate must be factory-installed, and not added by another party later. (Learn more about the role of device certificates here.)

Follow these steps to determine whether a valid, factory-installed Device Certificate is on your phone

  1. Connect the phone to the network and power it on. (If you will be using a computer to complete provisioning setup, ensure the phone and computer are on the same VLAN/subnet.)
  2. Via the phone menu, verify that the device has a valid installed client certificate.
    • SPA303 and SPA504G: Press Menu > 10: Product Info > 6 (Certificate: Installed)
    • SPA525G2: Press Menu > 10: Status > 1: Product Info (Certificate: Installed)

      You should see the message Certificate: Installed. If you do not see this, the phone cannot be provisioned for use with 8x8. Please contact the phone's previous owner or the previous service provider for assistance.
