it's not recommended to do this but if you go to the CUCM DB under the callmanager table you will see the autoregistration range parameters, one of those is the next DN to be assigned. manually change it to the start of your range.

The auto registered extensions are not going to magically be freed up after that.
The are still unassigned DNs in the system. Meaning, the extensions have been used, but not assigned to a device. The only way for them to be used again would be to delete the unassigned DNs that were used for the pool.
