In my experience, what makes a system easy to use is not minimization of
the number of options, etc. but rather how easy it is for someone who
does not have experience to get from "what I want to do" to "what to
do".

(Or as the traditional story goes, "There is a Toyota in the driveway.
I'm holding the keys in my hand.  What do I do next?")

In that regard, providing a large number of configurable parameters
isn't such a problem.  I.e., allowing the admin to specify the SIP
parameter is OK, because sipXecs propagates that decision to all the
places it need to be.  The problem is that when the user changes the SIP
password, the system doesn't hold his hand to let him know that he has
to regenerate certain IMDB tables and reload certain phone profiles.

The most demanding situation is initial installation, where what the
user really needs is an exhaustive list of *all* the things he needs to
do to get his VoIP system going to the point that he can make the first
phone call.
