Through this video, I'll show you how to regenerate the self-signed certificates on CUCM, IM&P and CUC, as they all use the same procedure, I'm doing this on an 11.0 release.
If you still have doubts about the procedure, if you meet the entitlement, you can reach us, the PDI Technical Advisors team, at www.cisco.com/go/pdita
In the above page, you can find our entitlement requirements, working hours, and how to open a case.
I also encourage you to review my FAQ before opening a case, I cover a lot of products in it:
