Hi,
the BLF lights comes online during call. Problem is when the watchers phone
is rebooted and the lights after reboot are off, but before restart they
were green/red.
I looked to the source code of presence module and I think that I found the
problematic part in function *update_subscrition()* in file
*modules/presence/subscribe.c*:
if(subs->expires!= 0 && subs->event->wipeer)
{
LM_DBG("send Notify with winfo\n");
if(query_db_notify(&subs->pres_uri, subs->event->wipeer, subs)<
0)
{
LM_ERR("Could not send notify winfo\n");
goto error;
}
if(subs->send_on_cback== 0)
{
if(notify(subs, NULL, NULL, 0, 0)< 0)
{
LM_ERR("Could not send notify\n");
goto error;
}
}
}
else
{
if(send_fast_notify && (notify(subs, NULL, NULL, 0, 0)< 0))
{
LM_ERR("Could not send notify\n");
goto error;
}
}
The presence module is always going to this line> if(send_fast_notify &&
(notify(subs, NULL, NULL, 0, 0)< 0))
and it sends just empty notify, it should send the last notify (which was
from the last call).
What is subs->event->wipeer and why do we need to check it?
Any help is appreciated.
