Overview

Bringing a previously used Cisco SPA phone over from a different VoIP provider? Provisioning (enabling it for use) is a snap as long as it has a valid factory installed device certificate. It's crucial that Cisco phone certificates are factory installed and not added later. Third-party phones must already have a valid device certificate to be used on 8x8 service.

The following is valid for Cisco IP phone models SPA303SPA504G, and SPA525G2.

Before You Begin

  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.
  3. Factory reset the phone.
    • SPA303 and SPA504G: Press Menu > 14: Factory Reset
    • SPA525G2: Menu > 9: Device Administration > 6: Factory Reset
