<p class="MsoNormal">I've used multi-san certs on at least a dozen installs and have had no issues at all. In fact, with a good SSL provider, you can use the same Multi-SAN on CUCM, CUC, UCCX, Expressways. I like how Digicert does it, just duplicate the cert
and make sure all of the hostnames are listed in the SAN.<o:p></o:p></p>

We're in the process of installing signed certs and we have the choice between multi-SAN cert with the publisher CSR and rely on the internals to have that cert distributed to the subs and the imp nodes -OR- go with individual certs.<br>
<br>
It's a last minute thing, so I still need to do some research, but I'm wondering what people have been doing out there. We're less concerned with cost than we are future stability. I know that this multi-san support is recent with v10.x - have they ironed out
the bugs? We're going with 11.5.<br>
<br>
Thoughts?<br>
