[Asterisk-Users] GotoIf voicemail message is too long??

[Jim Rosenberg]

If someone leaves a voicemail message and gets booted out of voicemail
because the message is too long, I would like different behavior than
if the # key is pressed. Anyone have a snippet of extensions.conf that
shows how to do this? How do I do a generic gotoif based on the result
code of an application?

What is the magic place to find where in "the documentation" <the WHAT!?>
the condition syntax is documented? Is there a URL for this?

What is the magic place to find all there is to know about "magic"
extension offsets (e.g. +101 if yatta yatta, +50 if yatta yatta, etc.)
