No, you need to change the function isup_calling_party_num_encode(), line 1718: param[0] = (is_odd << 7) | (is_international ? 4 : 3); Here 4 is the code for "international number", and 3 is the code for "national (significant) number". The code for "unknown" is 2 (check Q.763 section 3.10 for details). Eg. to send "unknown" for all calling party nature of address indicator, you can change the line to this: param[0] = (is_odd << 7) | 2; If you want to do the same for called party number, you need to do the similar change in both isup_called_party_num_encode() and isup_called_party_num_encode_no_st(). Also, are you sure this is what you want? From the Q.763 specification it appears that this will prevent eg. international calls, but I admit I do not know any details. But if you just want to prevent the calling number to be displayed at the other end, the correct mechanism is to set "presentation restrict", not to change nature of address indicator ... - Kristian.
