There is no generic mechanism for doing this currently: specifically
passing data back on a response or answer. The closest thing would be to
add a new frame type (frame.h) to Asterisk, put data on it (in an
ast_frame), propagate it through, and have it read/handled on the other
side. If you end up with specific questions you can respond back with
them, but you are sort of venturing into uncharted territory unless
someone else has an idea on how to better do it.
