[Freeswitch-users] fax files not saved

Oops, didn't catch the double underbar (the called script is not
evaluating that parameter). Thanks, fixed it.
You got me puzzled with your remark about session_in_hangup_hook. Had
to look it up on the wiki. My guess is that with session_in_hangup_hook
the variables get exported into the environment of the called
script/application and can be queried there directly. But I'm calling
the script with all the variables as parameters; the called script is
not evaluating the environment, but the command line parameters it was
passed.
Meanwhile, anybody any idea about why the fax file is only written to
disk sometimes?
Cheers,
Kurt
