That's true, but if they were only passed with the 'NEW' message, then
it would be like the setvar lines in iax.conf, set at the start of a  
call.

The discussion in that thread describes how to put them in their own
namespace, so they never collide with 'local' variables.

For me the solution over-complicates things,
a simple url style additional argument(s) to dial would do the trick.
say:

dial (IAX2/mexuar/tim?XYZ=${XYZ})
