I’ve been thinking about going via ACME for expressway. But I think we will try one more time using CCUC tools, which are supposed to be pretty good.

Unfortunately, Cisco doesn't allow for * certs with the UC platform. If this is for Jabber MRA, they recently added support for ACME certificates, but I haven't used that. The cheapest CA signed certs I've been able to find is ssls.com and the full set of certs for a typical cluster is going to set you back about $900 a year. They have a couple of Collaboration packages that you can use for the multiple domains. Also, they work well enough, but the support for ssls.com is pretty weak, so plan on at least a week to get your certs ordered, approved, and installed.

We use Entrust. But I think we had some sort of "Contract" that allowed for a specific number of certs to be issued, all on the credit system. Regardless of SANs.
But, you're right. Cisco collab is an expensive solution to provide certs for.
I'm really hoping that https://www.incommon.org/certificates/subscribe/ opens up to EDUs outside of the U.S. some time (soon).

Digicert have killed the fact you could issue a cert for host.sub.example.com on your *.example.com wildcard, instead they want to charge you extra for those hosts so now I'm shopping around. The good news is there's now other places that will do wildcards with unlimited reissues (which most call "unlimited server licenses").
I tried Comodo/Sectigo Positive Multi Domain Wildcard SSL which can even have multiple wildcards on the one certificate, but it only accepts CSRs for *.example.com, which UCM/UC/IM&P won't generate. But perhaps that's a limitation of the reseller I used. They also have the Comodo/Sectigo Multi Domain SSL Certificate (FLEX) which lets you have host SANs, but will charge you for each one.
Anyone had success with any other CAs recently?
