Re: [Asterisk] hangup a channel from bash - odd behavior

In that case perhaps this would work for you:

- when a call to the extensions that may need hanging up come in, set a global variable with that extension number to the channel name
- create an extension that's sole purpose is to Hangup
- use the ChannelRedirect application to redirect that channel to the Hangup extension

Nice way to work around the problem.

Debian 6 has a newer version of bash, so I wondered if it was an expansion quirk in the new version.

I downloaded v4.2.0, compiled, called it normally and with --posix.

Both methods worked... not sure where to go from here...

Just out of curiosity, are you running Debian 6.0.6?

What do the following show?

whereis asterisk

asterisk -rx "core show version"

grep ^`whoami` /etc/passwd

echo $SHELL

/bin/bash --version

Thank you Trev, based on your tip the problem has been solved. Bravo.

A priority was added to the target extension like this:
same => n,Set(GLOBAL(CHANTOKILL)=${CHANNEL})
 

and by adding this line to any other extension, call is hangup:
same => n,Set(result=${SHELL(asterisk -rx "channel request hangup ${CHANTOKILL}")})
same => n,NoOp(result is: ${result})
 

However, I'm still curious why the original code didn't work for me. This will remain an open question until someone solves this mystery

Cool!

said by dangmoo:

It worked normally when using the command without variables. Problem occurred only when a variable was involved

I understood.

I am curious, too, that's why I asked for the information.

I want to recreate your environment, but the full distro of Debian 6.0.6 contains 7 DVD's... it would be a waste of bandwidth and time to download a version that is different than the one you are using.

Sure SCADAGeo, sorry for delay.
I'm on a Debian Squeeze 32bit VPS, connected via SSH. Yes, it's the version 6.0.6 .
