Once more about Skype EWS

if you have SIP and SMTP (primary) different, then you need to make sure that autodiscover works ok.  You can redirect _autodiscover._tcp_smtp.domain to autodiscover.another.smpt.domain 443 if the later is defined and works ok.  Then you do not need to worry about UC SAN SSL.
