> 		The Inter-Asterisk eXchange (IAX) protocol is a completely IP based protocol.
> 		To create a conversation between to people via IP you use IAX with as the 
> 		method of transporting the audio.  To create an IAX channel you need to set
> 		up the IAX communications in your iax.conf file.

> 		The example above is very minimal and only sets up the basic settings to
> 		listen for connections and create them.  The same way that Apache listens
> 		for http requests on port 80, Asterisk will listen for IAX requests on port
> 		5036.
> 		</para>
> 		<para>
> 		Unfortunately the settings above are just a start and don't allow us to
> 		actually use that IAX connection.  So we have to add some channels so that
> 		in and out bound calls can be handled.

> 		In the example above you will notice that we have 2 entries to communicate 
> 		with the IAXTel service.  IAXTel is a free VoIP calling service and is used

> 		<para>
> 		We have 2 different kinds of connections to IAXTel, the peer and the user.
> 		This allows us to decide that inbound calls can come from one server and
> 		outbound calls could come from another.  This is extremely useful when you
> 		are handling a major network of Asterisk servers and are using IAX for
> 		trunking the servers together.
