I just found that if I remove
exten => send,n,Set(FAXOPT(maxrate)=14400)
exten => send,n,Set(FAXOPT(minrate)=2400)

I don't get the error.
My bad... but can it be considered like a regression ?

It isn't a regression. You are setting the {{minrate}} explicitly to {{2400}}, which *is* incompatible with V29.
