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.

Hi Daniel,
I understand your reply.The kamailio can set the "IIR" to send the OPTIONS
packets period.
But I don't found out the knowledge of the "IIR".
Would you give me some things how to do it.
Thanks!

Hello,
what are the operating systems? I haven't encountered any fragmentation
issues lately, Linux is able to handle UDP with payload up to 64kB.
Specific to your question, it may help in some cases to concatenate
headers, but the margin is rather small. If you know you are in a
controlled envir
Some udp INVITEs hit our network very close to the 1500 byte limit, and
we add 2 Record-Routes before we pass the INVITE to the end user. The
packet gets truncated in the SDP; "usually" it still works.
In our use case, I can't use gzip or TCP. We are already using textops
to convert to sho
IIR, the keepalives are sent stateless, so no transactions are create
for them. Just OPTIONS packets sent out, resulting in less load on
kamailio (well, comparing with normal transactional forwarding). The
mechanism behind detecting offline users with keepalives is based on a
counter kept in memory
Didn't know about that, it's interesting.
I'm curious about the load impact of this feature, since keepalives are
generally sent every 30 sec.

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.

Hi,
if the app crashes, it will just de-register the user after the
expiration time, since no re-register came in.

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

Hi,
You need to configure your client to un register when the app is closed.
For that, your client must send a REGISTER with Expires: 0.

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?
On 20.04.
Hi Daniel,
When the client's app is closed,the sip account may be registered
state,because the expired time may have some rest time.I want to implement
when the client's app is closed,the account also unregister.
How can I implement this function?Would you give me some advices?
Thanks!
