With CUCM you can auto-register phones provided a simple configuration is in place.  While this is not rocket science it’s nice to have the walkthrough to look back on so here it goes.

Ensure that the Cisco CallManager service is enabled by going to Cisco Unified Serviceability then select Tools>Service Activation and ensure that the Call Manager Service is enabled.

Next go to Cisco Unified CM Administration and select System>Cisco Unified CM

Once there you should notice that the default configuration has auto-registration disabled.

While auto-registration is disabled the phone will cycle through showing you that registration is denied. You can see the message in the following video:

To change this default behavior you will need to modify the Starting and Ending Directory number range as well as deselecting the checkbox.  You can see this in the following figure:

Once this has been done the phone can be reset and should pull a number from the auto range. Fun Stuff Huh?  Here is the phone registering.  A little shakey but taken with my Flip.  :)
