asterisk users - Dec 2005 - Need help with script from http://www.voip-info.org/wiki/view/Polycom+auto-answer+config

Hi,

can anybody help me with the allcall.agi script from 
http://www.voip-info.org/wiki/view/Polycom+auto-answer+config

When I run the script offline from asterisk it seems to work but inside my 
dialplan it does nothing - it does not write any calling file.

     -- Executing AGI("SIP/31-ee46", "allcall.agi|SIP/31 ")
in new stack
     -- Launched AGI Script /var/lib/asterisk/agi-bin/allcall.agi
     -- AGI Script allcall.agi completed, returning 0


Has anybody experience with this?

Thanks,
BK
