The interface is actually fairly similar, although the name is not identical
for obvious reasons, of course (it's not SIP).

I would be very much interested in a common syntax.  Unfortunately, it's not
quite possible in this case, because you can add multiple SIP headers with the
same name (and that's considered a feature!), but the namespace is flat for
IAX2 (i.e. if you set foo multiple times, only the last value endures).  The
interface is very similar to channel variables, CALLERID() variables, and the
like, though.
