I believe the NAPTR syntax itself is documented there...

The 'iax2:' gets replaced by EnumLookup with IAX2/, and the
'\1' get replaced by the dialed number. So if you call 
15145551212, what will get returned is IAX2/mtl-gateway/15145551212

You can put anything that is valid as an IAX2 Dial parameter in
there -- i.e. you could have 'iax2:user:passwd at iax2host/\\1' if
you wanted -- though I don't suggest you store that stuff in the
DNS unless you're *very* careful.

If you wanted to specify the context, as well, you could even do
'iax2:user:passwd at iax2host/\\1/context' I believe.
