[Asterisk-Users] Difficulty evaluating the return value of PlayBack (or any other extensions.conf command

[Andreas Sikkema]

Hi,

I just started to "play" with Asterisk today and while I'm 
writing some IVR-like functionality in extensions.conf I 
would like to take a decision based on whether playing a file 
succeeds:

exten => s,2,GotoIf($[Playback(${CALLERIDNUM}_personal) = 0]?3,501) 

So if Playback succeeds I want to jump to label 3, otherwise to 
label 500. Unfortunately Asterisk doesn't seem to understand what 
I want it to do:
Aug  6 15:46:42 NOTICE[524301]: pbx.c:4700 pbx_builtin_gotoif: Not taking any branch

I've been looking all over the wiki and google, but can't find 
any example doing what I want to do. Is it even possible?
