I have recently deployed a Lync Server STD running on a VM. It started out as a test server and now I would like to put it into production. Originally, all we wanted was internal chat, presence, and some video chat features so this is what I did. I created a self-signed cert (for testing) and got the chat and presence working. The issue with the cert is that I have an interal domain name ABC.LOCAL and an external domain name XYZ.COM. Users have their primary email addresses as XXX@XYZ.COM but the cert is obviously named as ABC.LOCAL as it was created by the Lync Server.
I am now ready to purchase a UCC cert and install it, as well as adding the ability to chat externally, and chat with other services like AOL, GTALK, etc.
My questions are:
What do I need to do to add the new cert, and when I do should all of the SIP Addresses change from abc.local to xyz.com?
How do I enable external access and the ability to connect to other services, and does this require another server (Edge)? We will have roughly 200 people using the service.
