Dear Users
Please advise how to detect a network lost at caller or callee side. I have tried timeout_sockethttps://kamailio.org/docs/modules/5.1.x/modules/rtpproxy.html#rtpproxy.p.timeout_socket and keepalives https://kamailio.org/docs/modules/5.1.x/modules/dialog.html#dialog.p.ka_interval method but nothing worked for me.
RTPproxy did not send timeout notification to Kamailio (Issue #1597https://github.com/kamailio/kamailio/issues/1597) while there is no options packet within a dialog. Is there any other method to cater such scenario.
Regards
Hamid R. Hashmi
Hi, have you tired SIP Session Timers (https://kamailio.org/docs/modules/5.1.x/modules/sst.html)?

Default Session-Expires time is 1800 sec. Can't we set Max Session-Expires as Min-SE because I didn't find any softphone which provides an option to change Sessions-Expire time? Call disconnected after 1800 sec.
Alex I already tried this but it didn't work. There are no OPTIONS packet to caller or callee.

I use it; it works. I would troubleshoot that angle further.
Alex's suggestion works fine for me as well.
Have you tried using dialog functions, like so:
dlg_manage(); dlg_set_property("timeout-noreset"); # don't reset timeout on in-dialog messages reception #set dialog properties. If any party disappears from the network - issue a BYE after timeout on OPTIONS dlg_set_property("ka-src"); # send keep alive OPTION requests to caller dlg_set_property("ka-dst"); # send keep alive OPTION requests to callee

Hi Alex/Sergeu/Hamid,
This is super useful and I had no idea about it!
Would you mind sharing your modparam settings for dialog module relative to keepalive?
I’d love to see what values you guys are using to have starting reference ;)
Thanks, Joel.

That's more or less how I roll, too.
I'm confused with these:
modparam("dialog", "ka_timer", 10) modparam("dialog", "ka_interval", 300)
Would this be more or less correct:
ka_timer = "run the keep-alive timer every Xs" ka_interval = "send options keep-alive packets every Xs"
But.. how are they related?
I think it's:
- The *ka_timer* is what sends the OPTIONS but they will only be sent every *ka_interval* to endpoints? So in the 10s example, the timer is run every 10s, it checks if *ka_interval *has passed since last OPTIONS was sent to endpoint, and acts accordingly... This means that the combinations of ka_timer=10 with ka_interval=300 would send OPTIONS ever 300-309s right?
Does this make sense?
Thanks, Joel.

Joel,
I'm not all too sure about the *ka_timer*, but it must be more or less how you described it. In my observation below, when caller disappears from the network, Kamailio sends 10 OPTIONS requests followed by 10 BYE if no reply received, which is probably the value of *ka_timer*.

Thank you. It worked for me. I set the params as below
#-------------- Dialog params ---------------- modparam("dialog", "timeout_avp", "$avp(i:10)") modparam("dialog", "default_timeout", 3600) modparam("dialog", "dlg_flag", 5) modparam("dialog", "db_url", DBURL) modparam("dialog", "db_mode", 1) modparam("dialog", "ka_timer", 10) modparam("dialog", "ka_interval", 30) modparam("dialog", "send_bye", 1) modparam("dialog", "timer_procs", 1) #--------------- SST params modparam("sst", "sst_flag", 6) modparam("sst", "timeout_avp", "$avp(i:10)") modparam("sst", "min_se", 90)
and use dialog funtions in request_route
dlg_manage(); dlg_set_property("ka-src"); dlg_set_property("ka-dst"); dlg_set_property("timeout-noreset");
and below is the call scenario.
