[Asterisk-Users] IAX Passing Variables

[Matt Florell]

We have gotten around this by just sending more data in the extension
that gets sent with the call and parsing it on the other side:

send a call to extension "1234" as "1234*ALERTINFO*ON" then you can
parse that out on the other Asterisk and set the variables over there
depending on the values of what you set on the originating server..

IAX and SIP as well as crossover PRI's all allow for instant
transmission of alpha-numeric extensions from Asterisk server to
Asterisk server. We have been sending thousands of calls a day like
this for over two years now. It's not the prettiest things but it
works well.
