Cron job, eighter parse every 10s both peer statuses, and create a call 
file that is in the callback context which parses the from peer callback 
database?

Or in a ideal situation an application that notices peer changes and 
creates a trigger. (Manager API Events)

Wait for Hangup, check Hangup->Channel in To5-DB
if in call Callback context
(extension script should handle pickup/call To5-DB/FromPeer)
