Probably it is lack of Asterisk know-how. ast_indicate_data looks 
promising - but I still do not know how to get the reference to the 
other call leg.


Caller          Asterisk            Callee
       leg 1                 leg2
                     <-------FACILITY---


Currently, if there is an incoming FACILITY message, the facility event 
is sent to chan_zap, which gets the AOC-D units from the event 
structure. But to forward it on call leg 1 I need to get a reference to 
the ast_cannel of leg 1. How do I get this?
