[Freeswitch-users] Fax *.tiff file deleted after call completion?

[Mick Stevens]

Hi FS Folks,

When testing fax receipt as per the wiki ( http://wiki.freeswitch.org/wiki/Mod_spandsp ) I "see/hear" the fax being sent & the *.tif file appear (briefly! :-)  ) in /tmp... But when the call has completed the *.tif file in /tmp disappears!?

I have tried incoming DDI's configured to my fax extension from two different carriers with the same result, both in terms of user experience & associated traces, so am "assuming" it's an FS problem (or, more accurately, a problem with MY fs config).

Any ideas guys, anybody else experienced this before?

Assoc. info...

fs extension config:

<extension name="test_rxfax_stream">
     <condition field="destination_number" expression="0123456789">
       <action application="log" data="Test CarrierX DDI for Fax ${destination_number}"/>
       <action application="answer" />
       <action application="playback" data="silence_stream://2000"/>
       <action application="set" data="fax_enable_t38_request=true"/>
       <action application="set" data="fax_enable_t38=true"/>
       <action application="rxfax" data="/tmp/FAX-${uuid}.tif"/>
       <action application="hangup"/>
     </condition>
   </extension>

In /tmp one minute... (observation: the fax file appears very small?)

pcap traces available on request - I see lots of t30 indicators in the traces & also data:v21? Not sure whether this is correct or not? I have tried enabling/disabling T38 to see if this makes any difference to no avail.

Any guidance gratefully received!

Festiveness....
