User who did this - Bill Radis (radisb) Attached to Project - sip-router Summary - Dialog never times-out when ka_timer < 10, even on 481 or 408(fake) response Task Type - Bug Report Category - dialog Status - Unconfirmed Assigned To - Operating System - All Severity - Low Priority - Normal Reported Version - Development Due in Version - Undecided Due Date - Undecided Details - In the dialog module (https://github.com/kamailio/kamailio/blob/master/modules/dialog/dlg_req_within.c) in line 264 there is this code: if(ps->code==408 || ps->code==481) { if(update_dlg_timer(&dlg->tl, 10)<0) { LM_ERR("failed to update dialog lifetime\n"); goto done; } dlg->lifetime = 10; dlg->dflags |= DLG_FLAG_CHANGED; } This code is for updating the dialog's lifetime when a timeout occurs (by a fake 408 reply) or a 481 is received. But in the call update_dlg_timer(&dlg->tl, 10) in the code above, the second argument is a hardcoded 10, which causes the dialog to refresh its lifetime to 10 more seconds, every time a timeout (or 481) occurs. But when ka_timer is < 10 secs this gets refreshed again before the dialog expires. I did a test with update_dlg_timer(&dlg->tl, 1) and it correctly works for values of ka_timer >= 2 I cant say the correct value, propably should be 1, so that the dialog gets expired the next second that the dlg_timer_routine runs. Anyway this value should be less than the ka_timer value so there should be a minimum valid ka_timer value. So maybe (ka_timer - 1) ?
