Are you sure you have the timers defined for the linkset?
/etc/asterisk/ss7.timers - provides the default values for all of them
and they need to be defined for each linkset
isup_timer.t22 = 15000
isup_timer.t23 = 300000 ; for ITU
;isup_timer.t23 = 60000 ; for ANSI
The code seems to do what it should:
https://github.com/asterisk/libss7/blob/master/isup.c#L5423
case ISUP_TIMER_T23:
isup_stop_timer(param->ss7, param->c, ISUP_TIMER_T22);
isup_start_timer(param->ss7, param->c, ISUP_TIMER_T23);
/* no break here */
case ISUP_TIMER_T22:
if (param->timer != ISUP_TIMER_T23) {
isup_start_timer(param->ss7, param->c, ISUP_TIMER_T22);
}
param->c->range = param->c->sent_grs_endcic - param->c->cic;
isup_send_message(param->ss7, param->c, ISUP_GRS, greset_params);
break;
Please note the 'no break here' comment - the GRS is sent from the next
case, so if you have the timer defined GRS will be sent every 5 minutes
for ITU and every minute for ANSI with the default values
