That's my fault; I had forgotten that Originating doesn't create a child
channel but rather a new independent channel. Hence, variable
inheritance does not apply.

You can use the IMPORT function [1] to pull the channel variables from
the Message channel. You would want to do this before you Answer the
Local channel, so as to prevent the Message channel from being hung up.
