[cisco-voip] [EXTERNAL] Re: Cost-Effective Public Certificate Authority for CUCM certificates

[James Andrewartha]

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?
