[Freeswitch-users] Freeswitch 1.6.19 and T.38 / INCOMPATIBLE_DESTINATION

[Dominique Jeannerod]

Yes, you're right, and i apologize for that.
I tested in the meantime (sent another mail in parallel), and it still
doesn't work.
I have the same error as in JIRA 10422 :
https://freeswitch.org/jira/browse/FS-10422

I've got " T38 IS NOT POSSIBLE on request " on the FIRST invite (not a
RE-INVITE)

> 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.
