So I tried the the Expires header for UNREGISTER and it is working fine.
Thanks for that. But the problem is that SIP Phone does not send UNREGISTER
event. It only sends REGISTER method periodically. So in my Server it will
be always online. So to overcome that I will be running e cron job which
will pool the online users from 'location' table of kamailio mysql db. But
the problem is, 'location' table does not get updated as soon as possible,
rather if I disconnect the SIP Phone and do 'kamctl ul show' it will be
still there for like 5 mins, after that it goes away. How can I change the
timeout of this,say to 2mins, meaning that after 2mins if there is no
response from the client ,Kamailio will mark it as offline. Where to change
that parameter?
