Hi,

I have the following scenario: When using a script in the conference caller controls, the hangup hook gets destroyed.
Affected script languages: Lua, Spidermonkey, Python, Perl

You can easily reproduce this effect using the below Lua scripts and adding the script application to the caller controls.
This is what happens:
- hangup without pressing a digit: hangup hook is called
- press a digit without script call, then hangup: hangup hook is called
- press a digit with script call, then hangup: hangup hook is not called

Looking into the source code of session_destroy, you can see that the hangup hook is in fact removed - which shold not happen when calling a script.
And there is no way to set it again after pressing the "*" digit.

Any ideas on this?


Thanks,
Melanie
