Scripting Lync Unassigned Number

In a previous article I outlined why should use the Lync Unassigned Number Feature.  If you haven’t read it please do so.  The problem I have is i have very few numbers that are contiguous for a few reasons but mostly because of how Phone Numbers are divided up among the telecom’s.  Essentially, telecom’s are no longer allowed to hoard phone numbers.  If they did, we could run into the IPV4 issue we’re hitting now with IP addresses (that is, imagine if a single telecom started hoarding all phone numbers, we could run out of phone numbers to issue and thus we may run into a need to add even MORE digits to phone numbers).  To help with this, when a telecom needs more phone numbers, they all retrieve phone numbers from a central pool (at least this is what our telecom provider told us when i asked why we could not get contiguous numbers).  Enough on that topic….long story short I’m left with ~6000 phone numbers…some are contiguous some are not.   Continue reading

Revoke Lync Client Certificates – Why should you do it AND what to watch out for

For those of you who do not know, about 99% of your logins to Lync are done via a certificate the Lync Front End provides you.  The reasons for why this is the default way is a topic for another blog post. Since I just told you that 99% of your logins to lync are certificate based, how does this impact a company for a user who just got abruptly fired and their AD account disabled?

The answer is, the users AD account being disabled does NOTHING to prevent a user from logging into lync should they already have a valid certificate.  Which leads me to my next question?
