[jm-asterisk at themarv...]

Is there any way to get Asterisk to keep redialing automatically if a number is
busy? How about the case where it is very difficult to get through, due to a
large number of people trying to simultaneously call the same number? In
particular, I am asking these questions for an outgoing SIP connection.

Is there a way via SIP to have multiple simultaneous calls in progress, each
attempting to call the number, and then stopping all of the extra's when one
succeeds in getting through?

A related question would be (i.e. if I decide to write some custom code for this
application): what happens when the destination number is on a crossbar or step
office? I'm assuming that when the destination is VOIP or a more modern POTS
switch that the busy condition is reliably detected and a proper SIP status is
eventually returned. But if the destination is crossbar or step is it possible
that the connection will actually be made in order for me to hear the remote
office generating a busy signal?
