Hi,

Has anyone successfully catch a SIGHUP signal when running a python AGI?  
I’d like to execute some actions when a user enters the AGI and hangup.  
I’m using pyst2. Should I be able to to see the SIGHUP sent to my application when AGI set debug is on?

Part of my Python code to detect hangup  
import signal  
signal.signal(signal.SIGHUP, signal\_handler)

def signal\_handler(signal, frame):  
print (‘User hangup’)  
sys.exit(0)

I’m using asterisk 14.2

The thing that puzzles me, is that once in a while I do catch the SIGHUP event and other time nothing.
