True. That's from the PBX point of view. But from the users point
of view, this is unacceptable. I'm not saying that asterisk is wrong
here, because the Alcatel 4400 which is behind our asterisk server
also doesn't provide the ringing sound (because it's not receiving
the ALERTING :-)

At this moment, for a certain range of numbers, I've added the
option "r" so that it gets a ring.. Oh man, my poor dialplan is
getting more and more abused.
