Hi to all from austria, I´m very new to freeswitch and I´m trying to get t38_gateway self working - but no success. for testing I use zoiper or spa2102 as t38 "device" - i have troubles in outbound direction: t38 device(internal) -> FS:t38_gateway self -> sip-provider (external - no t38 support) freeswitch sends no re-invite, I guess and Zoiper BYEs with Reason: SIP;description="Stale re-Invite" also see: http://pastebin.freeswitch.org/15439 inbound (t38_gateway peer) works fine - also when I do t38 device -> FS:rxfax my simple dialplan for the outbound call: <extension name="scpa" > <condition field="destination_number" expression="^1(.*)$"> <action application="set" data="fax_enable_t38_request=true"/> <action application="set" data="fax_enable_t38=true"/> <action application="set" data="execute_on_answer=t38_gateway self"/> <action application="bridge" data="sofia/gateway/scpa567/$1"/> </condition> </extension> Maybe I have to mention that I´m using Fusionpbx?! Thanks for any advice! I allready tried different examples I found, but no luck... Clemens
