Hello,

the usrloc keepalive are done on its timer interval:

  - https://www.kamailio.org/docs/modules/stable/modules/usrloc.html#usrloc.p.timer_interval

For the keepalive timeout I was misled by presence of the global variable in the usrloc, but was actually not exported by this module. I did it afterwards, just pushed to branch 5.4 as well.

While is not recommended to run both at the same time, imo nothing really bad can happen, you may see more keepalives for natted udp contacts (not for tls, tcp, ...).

As for an unorthodox and untested idea :-) : if you do not want to run from latest 5.4 branch yet, you can eventually set natping_interval to a very large value, like 20 years in seconds, so you are pretty sure you will do an upgrade before nathelper timer fires,

Cheers,
Daniel

Hello,

Is there any way to add those functions from the nathelper module to the usrloc module?

keepalive_timeout
natping_interval

I'm looking to use ka_mode feature from the usrloc module in order to have roundtrip time computed for each extension but because those functions are missing in the usrloc module and per documentation this functionality conflicts in some way with nathelper module it's not recommended to have both modules enabled.  Or maybe there is another way to have them "interconnected"?

Thank you.
