asterisk users - Jun 2008 - asterisk v1.6 monitor_exec

Hi all, 

can anybody tell me how I get asterisk calling an executable after a queue call?

only setting MONITOR_EXEC and MONITOR_FILENAME does not work anymore!
We use normal monitor to record _in and _out files. does work perfectly. 

But calling an exec does not do anything. 

We also tried setting MONITOR_OPTIONS=b 

Can anybody tell us, how we can get that running? 

We would like to call something like: 
/usr/bin/xyz -a -b -c 

Thank you very much, 
Martin
