[Freeswitch-users] t38_gateway self - no re-Invite?

[Clemens Ebentheuer]

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...
