[Freeswitch-users] Fax T38 problems in proxy media

Mon Nov 4 08:19:30 UTC 2019

Hi,

I have retested in default mode and FreeSWITCH refuse t38:
https://pastebin.com/raw/5LVvFdht

In the console I can see:
switch_core_media.c:4028 sofia/myprofile/number at 33.33.33.33 T38 REFUSE on
request

In my dialplay I set:
bypass_media=false
proxy_media=false
t38_passthru=true (same result setted or not. In sofia profile is setted
the param)
fax_enable_t38=true (same result setted or not)

I add to the dialplan a ringback with
ringback=%(1500,3000,425)

This is my sofia configuration (params section):
https://pastebin.com/usW3AKa0

What is wrong in my config?

Best regards
