the PHP-AGI script fails after it is executed and simply returns

I think this can happen by hanging up the call by one party, when SIGHUP
is sent to AGI script. PHP will exit on SIGHUP. It can be resolved by
initializing signal handler in PHP script (pcntl_signal) for SIGHUP and
doing nothing in it (return).
From res_agi.c:
enum agi_result {
AGI_RESULT_FAILURE = -1,
AGI_RESULT_SUCCESS,
AGI_RESULT_SUCCESS_FAST,
AGI_RESULT_SUCCESS_ASYNC,
AGI_RESULT_NOTFOUND,
AGI_RESULT_HANGUP,
};
so, AGI_RESULT_HANGUP == 4.
When Asterisk detects the hangup on the channel, it sends a SIGHUP to your
AGI.
I always set a signal handler on SIGHUP and do what makes sense to my
application: maybe some cleanup or syslog() before return() or exit().
Almost always exit().
