Step 2: Complete Manual Device Registration

Follow the manual registration process outlined in the documentation to onboard the Yealink T54W device to Webex Calling. This process configures the necessary SIP accounts and provisioning settings required for the device to register successfully.

Step 3: Verify Device Status

After completing the manual registration process, verify that the device status changes from "Status unavailable" to an active state in Control Hub under Devices.

Cause

Yealink T54W devices do not automatically provision with Webex Calling through standard auto-provisioning mechanisms. The device requires manual registration as a Cisco-managed third-party device to establish proper SIP account configuration and enable registration to Webex Calling services. Without this manual configuration, the device remains unprovisioned with disabled SIP accounts and no provisioning URL, resulting in the "Status unavailable" status in Control Hub.
