asterisk users - Jul 2008 - IAX to work on two ports: 4569 and 4570

Hi All;

How to let my Asterisk work able to deal with two kind of IAX channels, one work
on 4569 and one work on 4570 and able to receive and send calls on these two UDP
ports, depends on the destination.

Any advise?
Regards

There really isn't any good way.  The IAX2 channel will only bind to a
single
port.  You could start a secondary Asterisk server on the same machine and
pass traffic through, or you could use firewalling rules to divert from port
4570 to 4569.

The reason that I need to do this is:

I will have two Asterisk PBX's, and I need both of them to use same Internet
(so both of them will be behind NAT under same DSL router), in that case, how I
will distinguish on the router the calls that need to be send for box A and the
calls that need to send for box B?

Asterisk C will be in remote side, and will communicate with Asterisk A and B,
so I was look to have two ports on for IAX to be running on Asterisk C, for
example: 4569 and 4570, so when box C need to talk with box A, then it sends via
4569 and when it needs to talk with box B then it sends via 4570 port, and DSL
router does the routing based on these ports.

Is there any other solution?

I do not need to use VPN :) -

Why would you need to to that anyway?

Just set them to one port, but use different contexts to handle the
inbound traffic differently.

Again, I did not understand.

How the router will know if the call that came from Asterisk Box C need to be
routed for Asterisk Box A or Asterisk Box B?

Note: Asterisk A and B both behind DSL router, while Asterisk C in remote side,
both sides are connected via Internet.

Oh, for outbound traffic, you don't need to define other ports.  Simply
forward port 4570 on your router to port 4569 on Asterisk B.  Remember that
unlike SIP, IAX2 does not encode the port number into the protocol, so it'll
work perfectly fine this way.

If you're bound and determined to listen to port 4570 on Asterisk B, you
still
don't need to listen on two ports on Asterisk C.  Just leave off the port
number in iax.conf the specification for Asterisk C on box B.  Likewise on
Asterisk C, define the specification for Asterisk B to use port=4570.

There is no need for port numbers to be the same on both machines when talking
IAX.

The calls will be handled based on auth info and/or SOURCE port, which 
your NAT router would handle just fine.  It's similar to how two 
computers on your network can go to the same web site at the same time.

With SIP it CAN be a little more complicated.

On Box C, you define your IAX peers A and B in iax.conf. For your peer "Box
A", no special config is needed, it will use the default port 4569. For the
configuration entry for Box B, you add a line to the peer definition that
reads "port=4570". Box C will then try to reach Box B via port 4570.

On your DSL router, any traffic arriving on port 4569 is destined for Box A,
anything arriving on port 4570 is for Box B. You will therefore need to set
up port forwarding on the router. Incoming traffic on port 4569 (UDP) gets
forwarded to Box A, port 4569. Anything arriving on port 4570 you can
forward to Box B, port 4569. That will do the trick.
