Avaya deserve everything they get
Seriously, Avaya are a bunch of a*holes, Sue them to hell, bb!
Cannot code windows clients, seriously, I am sure an intern can do better than they poor excuse for a client. They have no Linux client, yet recommend you install their software on linux to lower TCO. What a bunch of idiots.
Now, if BlackBerry have a case, good for them, Avaya can rot wherever it is, I don't care.
