John,

Welcome to FreeSWITCH!

If this is an app that runs outside of FS and you just need to trigger
that code, I think Event Socket would be a much better fit.
http://wiki.freeswitch.org/wiki/Event_Socket

You'll be able to listen for nearly any type of even that you can think of:

If you're comfortable with Twisted, there are several modules out
there to get you going; I like this one [well, we did write it].
https://parseltone.org/browser/trunk/parseltone/eventsocket

The Parseltone code base is still taking shape, but it's used to
process 1000's of calls everyday. Checking the wiki and Google will
yield other options too.

While you'll be able to get access to this header in the events, I'd
consider making use of channel variables to track the path calls have
taken.


Good luck and happy hacking.
