Re: [SR-Users] Expect the kamailio's sip account is unregistered state when the client app is shutdown
Hi, You can take a look at this option: http://kamailio.org/docs/modules/4.2.x/modules/usrloc.html#usrloc.p.handle_lost_tcp It's a bit limited and doesn't work for: - usrloc db only mode - if you have separated edge proxy and registrar Thank you for information.. What can Kamailio do about clients, that exit abnormally (e.g. crash, turn off, ..) which do unregister properly? Can Kamailio send this expire=0 on behalf of these clients? Can Kamailio determine that a client got offline based on e.g. TLS connection or other heartbeats?

Re: [SR-Users] Expect the kamailio's sip account is unregistered state when the client app is shutdown
Hi, thank you for your reply.. Unfortunately I wansn't able to determine if OPTIONS packets are sent. When I observe the /var/log/syslog for kamailio messages I see only NOTIFY requests about presence, no OPTIONS. I assume they are not beeing sent, how do I turn them on? I found a module options while googling for a solution, but in my kamailio.cfg it is not loaded and I have no options.so module listed in /usr/lib/x86_64-linux-gnu/kamailio/modules How do I turn on OPTIONS and verify they were sent? By the way, just a thought, can it be that NATSIPPING works only with UDP? Because all UAs I use communicate over TLS. Does nat sip pinging work with TLS too?

Hi, IIR means If I Remember. Are you also using keepalives sent by clients? I often read that NATs don't refresh their mapping on incoming traffic, you may want to take a look at client keepalives.

Re: [SR-Users] Expect the kamailio's sip account is unregistered state when the client app is shutdown
I would be interrested in this too.. At the moment I am setting expires on my UAs to a low value (300) and when a UA exits SIP softphone application, Kamailio notifies it's offline status in 5 minutes. An immediate online/offline status would be better.. Is that possible with Kamailio?

Re: [SR-Users] Expect the kamailio's sip account is unregistered state when the client app is shutdown
No, it is not possible. However, it's not really an issue since sending an INVITE to the invalid location will result on a timeout which you can keep short (see the fr_timer) and then you can catch the timeout and behave as if there was no active registration. -Original Message- From: sr-users [mailto:sr-users-boun...@lists.sip-router.org] On Behalf Of Filip Malenka Sent: Monday, April 20, 2015 11:34 AM To: Kamailio (SER) - Users Mailing List Subject: Re: [SR-Users] Expect the kamailio's sip account is unregistered state when the client app is shutdown Thank you for information..
