Does ShoreTel Support NFAS Configuration?

Ok, let me start off this post by saying that there are many things that I do like about the ShoreTel phone system.  However, I have to say that I dont like that ShoreTel doesnt support NFAS for "bonded" PRIs.  When I learned this today from a TAC case I had opened, I was really disappointed.  In fact, IF a customer has this configuration and they dont want to go away from this, ShoreTel is automatically out as a VoIP choice.  Reliability is of upmost importance to businesses with call centers, governments, etc (and PRIs are the most reliable in my opinion).  Maybe in the future ShoreTel will support the NFAS configuration for bonded PRIs, but as of today, they dont.
