Anthony/all, I found while getting fax working that it seems that if api_hangup_hook is set /before/ answer in the following <extension name="Fax" > <condition field="destination_number" expression="^620$"> <action application="answer"/> <action application="playback" data="silence_stream://2000"/> <action application="set" data="api_hangup_hook=system /usr/bin/php /var/www/fusionpbx/secure/fax_to_email.php email=acrow@integrafin.co.uk extension=620 name=\\\${last_fax} messages="/> <action application="set" data="last_fax=${caller_id_number}-${strftime(%Y-%m-%d-%H-%M-%S)}"/> <action application="rxfax" data="/opt/freeswitch/storage/fax/620/inbox/${last_fax}.tif"/> <action application="hangup"/> </condition> </extension> That rxfax strangely fails - the calling fax machine never gets the tone to start sending and T4 is retried until rxfax gives up. If it's placed as above it works fine. Not sure if this is a bug or intended and the docs on the Wiki need changing.
