Help with new CUCM subscriber/security

[Nick Halbert-Lillyman]

We've recently installed a new subscriber in our CUCM 8.6 cluster.

Whenever we try and register a phone to the new subscriber, it says "Registration Rejected: Security error".  I can register phones to the existing subscribers fine.

Do we need to add this server's certificate to CAPF or something?  How would I do that?

Please note we are not using CTL.

I should also note that I've tried several phones and factory resetting them...
