Brian,

could you please confirm if there is a way to accept T38 in initial invite with FS 1.6.15, and if not, which version I have to downgrade to in order to get this behavior back (I really need it and can’t make it without it) ?

Thank you

Who knows we could probably make it work, but I have nothing that does this.  I just have avoided it due to how its usually treated.

There is nothing wrong with sending T.38 in the initial invite, if the
call is from something that knows T.38 is usable at the very start of
the call. However, its best avoided, as so much equipment treats this as
an error condition.
