I know that there are some people on this list that use Asterisk a
decent bit.  Those that do... are you familiar with GrandCentral?  If
so, how do they compare?

I really like the control that something like GrandCentral gives you.
The ability to choose where you receive a call (home, cell, work, etc)
based on who is calling or when they are calling is a killer feature for me.

Alas, there are just too many potential gotchas with that service to
really commit to it other than as a play-thing (or as a number passed
out freely to businesses and warranty cards and the like).  What I would
like is that kind of control... but in a way that *I* control it all!

So no calls being routed through a 3rd party server; no voicemails
stored on their server; no need to upload all of my contacts to a search
company; etc.

Asterisk seems like it might be able to do all that... but who can tell?
 Their site is horribly disorganized and when you do find a "feature"
page, they spend all their time in an acronym frenzy.

So... does anybody know?
