[Freeswitch-users] possibly fixed: fax files not saved

Today I spent a couple of hours testing various things in regard to this
problem. As far as I can tell, the files do not go missing if I have
    <action application="answer" />
    <action application="playback" data="silence_stream://2000"/>
coming before 
    <action application="set" data="api_hangup_hook=system ...

But if the api_hangup_hook comes before answer, then it happens. Why?
Well, that's beyond me.

Hope this info helps others too.
