When a channel hangs up, Asterisk sends a SIGHUP signal to the AGI. If the 
AGI did not establish a handler for the SIGHUP, the AGI exits. If the AGI 
established a handler, the AGI can choose to ignore the signal or execute 
appropriate code -- like clean up files, write a CDR to the database, etc.

If the AGI is started when the channel is "live," you should use agi() and 
catch signals appropriately. If the AGI is started when the channel is 
"dead," you should use deadagi().
