Removing the F on sent numbers is very simple.
Original code:
void isup_set_called(struct isup_call *c, const char *called, unsigned
char called_nai, const struct ss7 *ss7)
{
if (called && called[0]) {
if (ss7->switchtype == SS7_ITU)
snprintf(c->called_party_num,
sizeof(c->called_party_num), "%sF", called);
else
snprintf(c->called_party_num,
sizeof(c->called_party_num), "%s", called);
c->called_nai = called_nai;
}
}
Modified code:
void isup_set_called(struct isup_call *c, const char *called, unsigned
char called_nai, const struct ss7 *ss7)
{
if (called && called[0]) {
snprintf(c->called_party_num,
sizeof(c->called_party_num), "%s", called);
c->called_nai = called_nai;
}
}
On chan_ss7 this is a configuration file option.
