Auto registration pool exhausted....auto roll back?

My client has a CUCM 6 cluster with 500 phones configured for the auto reg pool (1000 - 1500).  The pool has been exhausted - in that the highest number has been used (DN 1500).  However, lower DN numbers have been freed up.  It does not appear that the CUCM is rolling back to look for open numbers.  Is this a bug?  Is there a fix?

Auto registration pool exhausted....auto roll back?

CUCM only keeps 3 values related to auto-registration

Start DN, End DN and Next DN.

Next DN first value is StartDN-1 and it goes all the way until next NextDN = End DN, once that happens the pool is exhausted and you need to define a new range. It doesn't look to find whether you changed those DNs and now they're free or start over again.

If you need more devices to be auto-registered define a new range.

Jeff,

Go to the

Call Roouting --> Route Plan Report

Drop down the left hand search to Unassigned DNs

Search for patterns begining with 1

If these are your AUTO REG Numbers the delete them.

Try AUTO REG a phone again
