That's pretty much the size of it, yes.

I forget the precise problem, and it's been too long since I perused the
code, so I can't explain it with adequate specificity.  But that is how
it works.

If my approach works with the way your dialplan code is written, I'd say
that's your best bet.  If not, then.... ???  I don't know.

Sorry I can't be of more help.
