[Asterisk-Users] Queue Callback

[Tyler]

Hello,

Does anyone have any information on configuring app_icd (or know of any
way to do it with the dialplan) that would allow a user holding in a
queue to hang up, and have the system call them back when their place in
line comes up next?  

I can (obviously) allow them to '0' out to voicemail or something, but I
can only find vague references to app_icd and 'OrderlyQ' for doing what
I want to do...

Anyone?

Bueller? ;-)

Thanks
