Daniel 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. Regards Hamid R.

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 On Wed, Aug 29, 2018 at 9:46 AM Alex Balashov <abalashov(a)evaristesys.com> wrote:

Hi Joel, I personally use the values from examples: modparam("dialog", "ka_timer", 10) modparam("dialog", "ka_interval", 300) modparam("dialog", "send_bye", 1) On Wed, Aug 29, 2018 at 11:48 AM Joel Serrano <joel(a)textplus.com> wrote:

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.

Sergiu 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.

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.
