You *can* play a welcome message without answering the line, however,
this doesn't always work. eg, I tried this config on my PRI in Australia
(Telstra) and:

a) Calling from a standard analog line I got my welcome message as
expected
b) Calling from a mobile (Optus), I heard silence until the call was
answered.

If this worked properly (ie, to all phones) then it would be very useful,
however, since it doesn't always work, then I can't use it in my situation.

If anyone has comments/suggestions on how to make it work, then I would
appreciate that.
