According to <a href="http://lists.digium.com/pipermail/asterisk-users/2011-September/266075.html" target="_blank">http://lists.digium.com/pipermail/asterisk-users/2011-September/266075.html</a> the variable names have changed, however I couldn&#39;t find an updated documentation or understand from the mail reply, what I have to change in the example above.<br>

So, can somebody please tell me where to get an updated documentation or how to fix my problem? I am using Asterisk 1.8.10.1.<br>
<br>
Thanks :-)<br>
