[asterisk-dev] Need to run an AGI from dialplan only upon call hold

[uma udupi]

Thanks for the suggestions. I made changes to res_agi to save the PID of the app into a channel variable (struct ast_chan). Upon UNHOLD event, I could kill() with that PID.

Alternatively, since res_agi already knows this information, he could
create a dialplan function or simply an ast_agi_ api call to retrieve
that value.  It's currently only passed into the agi processing loop,
but it could be very easily stored in a channel datastore.
