I had some difficulty with that posting on the WIKI, too.  In the end it 
turned out that I didn't realize that you will often need to restart 
asterisk after making changes to iax.conf like this. In case you need 
it, here's what I use:

If I have two locations:

Location 1: 123.123.123.123
Location 2: 234.234.234.234

In iax.conf on my "1" box, I use:
[ast2-in]
type=user
secret=pass2
context=my_context_on_2
disallow=all
allow=ulaw

[ast2-out]
type=peer
secret=pass2
username=ast2
host=234.234.234.234
disallow=all
allow=ulaw


In iax.conf on my "2" box, I use:
[ast1-in]
type=user
secret=pass1
context=my_context_on_1
disallow=all
allow=ulaw

[ast1-out]
type=peer
secret=pass1
username=ast1
host=123.123.123.123
disallow=all
allow=ulaw


Then in extensions.conf, if I wanted to use 1XX extensions for Location 
1 and 2XX extensions for Location 2, I could use something like this:

extensions.conf for Location 1:
exten => _2XX,1,Dial(IAX2/ast2-in:pass2 at 234.234.234.234/${EXTEN})

extensions.conf for Location 2:
exten => _1XX,1,Dial(IAX2/ast1-in:pass1 at 123.123.123.123/${EXTEN})


I hope that makes sense.
