The iax configuration file /etc/asterisk/iax.conf contains a variety
of samples and comments that should give you enough information to
play with and if you have any trouble you can ask a specific question
here which is far more likely to get you going than a general "I don't
know but how can I do it?" post or a post containing a whole bunch of
questions. Please note that this is not meant as criticism, I am just
trying to be helpful and tell you the facts.

Another good source is the Asterisk Wiki at http://www.voip-info.org.
However, you will need to browse a little to find the various bits and
pieces of interest to you.

If you are in BA, you might want to consider contacting Nicolas Gudino
and pay him something for his time to sit down with you setting up IAX
peering on your servers and teaching you in the process so you can do
it all by yourself in the future. And even if you don't have any
budget to pay somebody you might still want to hook up since local
Asterisk user groups, even tiny ones with only two or three members
can be helpful when it comes to sharing tips and tricks and exchanging
information.

The use of the switch command is much dependent on the structure of
your dialplan. It is generally not advisable to export and import the
entire dialplan but only those contexts you really need and only into
contexts where you really need them. To give any more specific advice
would require taking a closer look at the relevant dialplans.
