I will show you what I did. This is what I added in function tsx_callback() 
in sip_reg.c

if(tsx->status_code/200 == 2)
{
    //do something
}
else
{
    rdata = (event->body.tsx_state.type==PJSIP_EVENT_RX_MSG) ?
        event->body.tsx_state.src.rdata : NULL;

    //added - Start
    pj_time_val delay = { DEFAULT_RETRY_TIME, 0 };
    regc->timer.cb = &regc_refresh_timer_cb;
    regc->timer.id = REFRESH_TIMER;
    regc->timer.user_data = regc;
    if (pjsip_endpt_schedule_timer( regc->endpt, &regc->timer, &delay) != 
PJ_SUCCESS)
    {
        PJ_LOG(5,(THIS_FILE, "pjsip_endpt_schedule_timer FAILED!!"));
    }
    pj_gettimeofday(&regc->last_reg);
    regc->next_reg = regc->last_reg;
    regc->next_reg.sec += delay.sec;
    //added - End
}

>From what I have seen, with this code pjsip freezes when I get a 404 for 
REGISTER (at the 2nd retry).

Hope you can reproduce it.

Thanks,
