[Asterisk-Users] Call redirect with *

[Michael George]

I would like to redirect a call from one IAX "destination" system to another
and I'm wondering if it is possible and if so, how.

Here is an explanation of what I mean:

Point A is our main office.  It has the lines from the PSTN and it converts
them to VOIP traffic on an * box.

Point B is a satellite office with a small number of people working who work
there.  It also has a * box for handling calls sent in by Point A.

Point C is the home office of one of the employees of the office at Point B.
Sometimes he's in the office, sometimes he's not.  We will also have a * box
there for handling * calls.

What happens is that calls come in to Point A.  Based on the dialed number,
they may be routed to Point B immediately.  At Point B the greeting is played
and the caller is asked for an extension.  If their entered extension is the
extension of the Point C employee (who is not in the office that day but is
working from home), then the call is routed from Point B to Point C.

The problem is that going from Point A --> Point B --> Point C consumes 2x the
needed bandwidth at Point B and introduces latency, another point of failure,
etc.  What we would *like* is for Point B to be able to parse the extension
and, upon determining that the call is destined for Point C, have a way
within the protocol to tell Point A: "Hey, could you please take this call and
send it to (user:pass at Point C/context/extension)?"

That way, the call would go from Point A --> Point C, even though the
extension parsing and "control" of the call came from Point B (obviously, once
the call is re-routed from Point A --> Point C, Point B can no longer exercise
any control over it).

Is this possible?  Perhaps this can be accomplished with the "switch =>"
statements in extensions.conf (I do not understand the switch very well)??

Thank you.
