[Fwd: Re: [Asterisk-Users] IAX config documentation]

[Brian Cuthie]

Boy after really digging into this, I have discovered that there is more 
information about each of these topics than I previously realized. 
Strangely, searching the wiki on "iax" returns exactly nothing. But 
searching on iax2 does start to dig up some good stuff.

Sorry for the hassle. Tough day.

I know that this stuff is. What I'm looking for is an overview of how 
these features work in the context of IAX. For instance, trunking is a 
concept I think we all get. But how do you use IAX to establish trunking 
between two switches?  What's the effect of turning the "transfer" 
option on? How are dialplans shared between switches that are connected 
via IAX? What kinds of authentication are supported? How are keys managed?
