This is triggered by doing anything new in your script. So if your channel is blocking on something while its being hungup, it will eventually pick up on it when it exits the blocking call and runs one of many methods that have a check for if it has to run the hangup hook. Manually calling hangup is a bad example, because you know you are hanging up so there is no real need to trigger the hanguphook but if you want to ensure it does you have to call session.ready() one last time.</div>
<div><br></div><div>If you are writing a critical application, consider C. It's much more robust when it comes to this type of problem because it supports threading. Or consider ESL external scripts where you can run async operations and get events etc.</div>

<p class="MsoNormal">Hi,</p>
</div>
<div>
<p class="MsoNormal"><br></p>
</div>
<div>
<p class="MsoNormal">I have tested the hangup hook function using the following
javascript. During the speech in the call I hangup the call to see the result.
Sometimes hangup function works, but sometimes it did not. The chance of fail
is about 1 out of 10. I am running windows XP, FS git version cloned and
compiled at end of Jun. Does anyone meet the same problem? Or do I make some
mistake in the script? Thanks.</p>
