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@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

I think that i tested in the default mode and I receive from FreeSWITCH a 488, but I'm not sure at this moment. I will retest the next monday.

Best regards

Hi, i experienced this 2 years ago with the latest version that time 1.6.17, likely no will to change for the current version. For short, proxy media does NOT seem to work at all for `t38-passthru=true`.
My solution was to switch to normal media mode for that option to take effect.
You should give it a try.

Hi, I have sended another email to the list with attachments. I think
that the list not accepts attachments, sorry.

I have several FreeSWITCH's (latest version from deb packages: 1.10.1
-release-12-f9990221e6) and I have problems with faxes in proxy media
(in bypass-media works).
In the sofia.conf.xml I have setted the param t38-passthru=true

If the flow is:
1. Initial INVITE
2. Re-Invite from one of the legs with t38 sdp
Result: works

But if the flow is:
1. Initial INVITE
2. Re-invite from one of the legs changing the media (at answer)
3. Re-invite from one of the other legs with t38 sdp
Result: not works

I tried with "soa_enable=false" without luck.

FreeSWITCH seems that hangs the sip transaction.

This capture is the first reinvite (in the flow, the "showing" line):
https://pastebin.com/raw/X4zrUr4k

This capture is the reinvite with the t38 negotiation sended by the
receiver (Grandstream ATA):
https://pastebin.com/raw/KCXD51aH

And this with the response (200ok) accepting the t38 negotiation):
https://pastebin.com/raw/ifqtPN8L

How I can debug the problem?

Best regards
