Unable to register Room bar on CUCM

[valenciaa]

Im trying to get the Room Bar register to CUCM but i keep getting the following error

SIP registration failed: 404 Not Found / Unable to find device/user in database. Verify SIP configuration and connectivity to SIP proxy.

The device pack has been uploaded to the CUCM

Have you created the device in CM under Devices > Phones?

Did you follow all the other steps in the Cisco Unified Communications Manager Device Package Installation Guide, specifically those around which services on which nodes need to be restarted to get the new files to be used?
