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.
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 SPA303, SPA504G, and SPA525G2.
Before You Begin
- 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.)
- 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.
- Factory reset the phone.
- SPA303 and SPA504G: Press Menu > 14: Factory Reset
- SPA525G2: Menu > 9: Device Administration > 6: Factory Reset
Provisioning the Phone for Use with 8x8 Service
Note: Ensure the phone and computer are on the same VLAN/subnet to complete the following steps.
- Find and note the phone's IP address.
- SPA303 and SPA504G: Press Menu > 9: Network.
- SPA525G2: Press Menu > 10: Status > 2: Network Status.
- On a computer on the same network as the phone, enter the phone's IP address.
- Log in to the web GUI and point the endpoint to 8x8's configuration server:
- Admin Login > Advanced > Provisioning > Configuration Profile
- Click Submit All Changes. (Phone should reset.)
- Once the phone boots back up, manually reboot the phone again.
- Following the manual reboot, wait 30 seconds. The phone will reboot again on its own. It should display Phone not active yet.
- Activate your phone using the activation code provided in your welcome email.
- Press Menu > Device Administration > Profile Rule.
- Enter the Profile Rule: https://lscfg.8x8.com/linksys/custom.cfg

- Press Menu > Device Administration > Profile Rule (should be blank again).
- Enter Profile Rule B: https://lscfg.8x8.com/linksys/$MA.cfg
