Hello James,
on easy alternative would be to use the nathelper pinging method. It also
supports UDP ping, and you can specify it on a registration level with a
certain flag if you want to ping or not.
Cheers,
Henning

Subject: [SR-Users] apply keepalive to only udp
Hello,
I wanted to know if this can be accomplished, or if I'm doing something wrong.
What I'm hoping to accomplish is to have kamailio periodically send OPTIONS
packets to endpoints that are connected over UDP only.
As of right now, I currently have the following configured under usrloc:
modparam("usrloc", "timer_interval", 5)
modparam("usrloc", "timer_procs", 2)
modparam("usrloc", "use_domain", MULTIDOMAIN)
modparam("usrloc", "db_url", DBURL)
modparam("usrloc", "db_mode", 0)
modparam("usrloc", "ka_mode", 1)
modparam("usrloc", "ka_method", "OPTIONS")
modparam("usrloc", "ka_from",
"sip:p...@sip-domain.com<mailto:sip:p...@sip-domain.com>")
modparam("usrloc", "ka_domain", "sip-domain.com<http://sip-domain.com>")
modparam("usrloc", "ka_timeout", 125)
modparam("usrloc", "ka_interval", 60)
With these parameters, all endpoints will be sent OPTIONS packets periodically
as expected. When setting "ka_mode" to "4", as expected, endpoints registered
with UDP only receive OPTIONS packets; which is what I wanted.
The issue that I'm having with these parameters is that endpoints registered
with anything other that UDP are triggering a contact-expired event after a
little over 2 minutes. I have the registrar set to 3600 as an expiry; I'm
assuming the contact is expiring due to the "ka_timeout" value.
--------------------------
Is there a way to only have keep-alive packets/ and timeouts apply to endpoints
registered on UDP?
Thank you.
