Who knew? Hey TP, I learned something new today!

Another approach, is to establish a signal handler -- so you can handle 
the signal :)

I write my AGIs in C (because you can execute xxx AGIs written in C in the 
time it takes to load PHP and parse your script) so it looks like this:

// trap SIGHUP -- caller hung up
         signal(SIGHUP, (void (*)(int))(int)hangup);

When the caller hangs up, Asterisk delivers a SIGHUP to the process 
created by the agi() application. Execution of your AGI will then continue 
with your signal handler where you can clean up temporary files, roll back 
database cruft, etc.
