Adding trusted domains to the room system
If the domain name used in the Skype for Business account’s SIP URI is different from the domain
name on the Lync or Skype for Business Web Service certificate, the room system might not
connect to the Lync or Skype for Business Server. If this occurs, a dialog box might appear asking if
you want to trust the certificate, but this dialog box disappears quickly thereafter.
In this situation, you need to add the domain name specified in the
Subject Name
and
Common
Name
fields of the Lync or Skype for Business Web Service certificate to the room system.
