CUCM 12.x Auto registration

[Nkechi Latunji]

Hello

I cant auto register either SIP or SCCP device on a new cluster. I have enabled auto-registration  for the subscriber and Default CCM Group. Option 150 is configured for the voice dhcp scope.

Any idea why no phones will auto register?

@Nkechi Latunji  can you check call manager service is activated in serviceability ?

Only servers that have CUCM running show under system -> Cisco Unified CM, which is where you enable auto-registration.
