## Applies To

- Poly Devices

## Resolution

Follow the steps to [Manually Provision a Poly Phone](/support/docs/manually-provision-a-poly-phone).

## Cause

The phone is not provisioned correctly.

## Additional Information

If the phone is still not working after provisioning, check to see if it is obtaining an IP address. See [Find the IP Address of a Poly Phone](/support/docs/find-the-ip-address-of-a-poly-phone).

- If no IP address is showing then the device is not connecting to the network so check connection.
- If IP address is showing, try moving the device to a known working location.
- Try connecting the device to a different network.

If none of these steps work then there may be a fault with the phone. Create a case with 8x8 Technical Support for further assistance.
