asterisk users - Feb 2005 - VMS - AGI

Hi list,
     I would like to use the * VMS application with a GSM network, I know
that * support Unavailable and Busy Redirecting Reason in the
extensions.conf but, what's about the No Reply ??

Then, I know that doing a debug on the PRI, I see the redirecting reason...
My question is; is there anyway to obtain this redirecting reason through
perl AGI ??

Thanks in advance .
Angel.
