hello, all of users:
I have implemented cha_ss7 in china. initially, the chan_ss7 can not support the call group. i modify the code. now the problem is that, both sides can hear the ring, but i can not hear the voice from each other.
i think the ss7 does not send the voice steam to the destination.
in chan_ss7, i added:
static struct ss7_chan *cic_hunt_even_mru(struct linkset* linkset) {
struct ss7_chan *cur, *prev, *best, *best_prev;
best = NULL;
best_prev = NULL;
for(cur = linkset->idle_list, prev = NULL; cur != NULL; prev = cur, cur = cur->next_idle) {
/* Don't select lines that are resetting or blocked. */
if(!cur->reset_done || (cur->blocked & (BL_LH|BL_RM|BL_RH|BL_UNEQUIPPED|BL_LINKDOWN))) {
continue;
}
/* if((cur->cic % 2) == 0) { */
/*change to this*/
if(((cur->cic % 2) == 0)&&0==strcasecmp(cur->link->name,linkname)) {
/* Choose the first idle even circuit, if any. */
/*end of change*/
best = cur;
best_prev = prev;
break;
} else if(best == NULL) {
/* Remember the first odd circuit, in case no even circuits are
available. */
best = cur;
best_prev = prev;
}
}
cic_hunt_even_mru if(((cur->cic % 2) == 0)&&0==strcasecmp(cur->link->name,linkname)) {
my environment is:
asterisk-1.4.20
chan_ss7-1.0.91
Openvox D410P
===========================
anyone has an idea for the problem?
please give me some hints!
thanks!
