Cisco VoIPs no longer register with Subscriber- Certificate problem?

[R_Acuti]

Hi gang,

I recently stood up a new VM cluster in our lab, running 11.5. I migrated all of the phones successfully, to a Subscriber.

Later, I noticed that the Corporate Directory was not working, and followed a few false leads that had me regenerating certificates. Eventually, I fixed the Corp. Directory issue and all was well.

When I returned this morning, I found all phones had moved to the Publisher. I cannot seem to force them back to the Subscriber.  The Option 150 statement in the DHCP pools is correct. I have verified that all VoIPs can reach all 3 Call Manager servers.

I think I fumbled a certificate somewhere during my earlier troubleshooting.

Which certificates affect the registration process?

Do I need to re-start the TFTP service on each node if I regenerate a certificate?
