I'm coming to this thread late, but we're just getting to the concept.
We are combatting "spare" wireless devices being "found" months after they've been deprovisioned - the users then expect them to continue working.
We think we'll query WaveLink/Avalanche to see if the devices is in the management platform prior to letting it on the air.
So far we think it has HTTP and SQL methods, but aren't finding much advice on how to make the query.
Has anyone gotten it working since this thread started?
I'll forge ahead and update the thread with what we learn.
