[Freeswitch-users] start perl-script after receiving fax

Hi, I would like to receive (T38/T30) faxes with rxfax. I think this won't be a problem to do so in dialplan. But, after (succesfull) receiving I would like to call a perl-script which needs some variables, at least the fax-file name, and some other infos. How can I call this script with variables afte receiving? regards, Benjamin
