Not sure about the Brazil variant, but ITU-T Q.764 defines the en-block
dialing to end with ST.
0xf is ST signal it means 'end of dialing' or 'number is complete', so it
should understand it and your problem is probably somewhere else.

As Johann Steinwendtner have noted you receive the number without leading
0, but you send it with 0 - this or as Gustavo suggested
Screening/Presentation may be the problem.

Yes, it is hardcoded for ITU switchtype - check isup.c isup_set_called().
You may try to modify the code, but i don't think that this is the problem.
