Yes, its exactly this, If you try what I outlined you can regain the previous behavior. It was wrong to blindly accept t.38 and switch over. :) Plus we handle the fallback correctly now. On Mon, Mar 27, 2017 at 1:49 PM, David Ponzone <david.ponzone@ipeva.fr> wrote:
Brian,
I noticed a behavior change with t38 between 1.6.6 and 1.6.15. With 1.6.15, if I receive a INVITE including PCMA/PCMU/t38, it got rejected with T37 REFUSE. If I enable T38 in vars.xml, it’s still rejected with T38 NOT POSSIBLE ON REQUEST.
Is it related to the change you mentioned ?
Thank you

You do NOT want 1.6.13 PERIOD if you're doing faxes or anything t.38 related. You're in for some pain.
Use 1.6.14 or v1.6 branch which also has the final patches for 1.6.15.

Hi Brian,
Thanks for informing us. I just switched back to 1.6.13 an hour ago due to users complaints (and did not have the time yet to dig more). However, I have the following settings for all users:
<action application="set" data="fax_enable_t38_request=true"/> <action application="set" data="fax_enable_t38=true"/>
which, according to your message above, should work ok. Anyway, I'll wait to 1.6.15...
Thanks, __Yehavi:

To clarify this work around will work on 1.6.14:
If you wish to retain the previous behavior you can set fax_enable_t38=true in your vars.xml, You can also not set that and just set refuse_t38=true if you wish to never do t.38.

FreeSWITCHers,
In 1.6.14 we did a slight behavior change related to T.38 re-invite acceptance. Before 1.6.14 we would by default accept the re-invite even if t38 wasn't enabled and switch to UDPTL mode. This was an incorrect behavior to do by default.
But one caveat in 1.6.14, We by default 488 the fax but switch the media mode to UDPTL which is also a bad behavior fixed in (FS-9943) slated for 1.6.15.
If you wish to retain the previous behavior you can set fax_enable_t38=true in your vars.xml, You can also not set that and just set refuse_t38=true if you wish to never do t.38.
These default behaviors are fixed in our next release 1.6.15.
Thanks,
