Right.

Voiceglue has <exit>, but it currently does nothing with the
variables names and values supplied to it via "namelist".

Asterisk's Agi() command does not return a value directly,
so there's no way to do that explicitly.  Also, VXML has
no way to return a single value, only the list of name/value
pairs via <exit>.  That's why I suggested what I did, in
which case you could set any number of asterisk dialplan
variables from the <exit> command.
