Is your contact centre system CCX or CCE ?
This is a CUCM Phone and not "Finesse".
You cannot log into a Phone with Finesse - unless Finesse has CTI Control of the agent phone (or UDP).
If CCX you assign the RMCM Application User to the device - full details below (or look at the UCCX Admin guide).
If UCCE, assign the pguser to the phone
But your issue looks like the phone itself if not registered?
This is a CUCM issue and not a Finesse issue.
The phone must be configured on CUCM (as you have done), but then the phone itself must have a valid IP address and have a TFTP address of CUCM either configured via DHCP or manually on the phone) - so it can pull down the config.
Google "CUCM Phone Registration issues" or similar.
