Hello,
actually the expires processing on keepalive was done in a callback function triggered only by nathelper, only sending keepalive and computing roundtrip was done on usrloc internal timer callbacks. I pushed fixes to master and 5.4 branches, I tested briefly with a tcp contact and all seemed ok. Let me know if works for you as well.
Cheers, Daniel

Hello,
It's sitting in the memory until the expiration time it's arriving. See below the ul dump output:
Every 2.0s: /usr/local/sbin/kamcmd ul.dump Wed Sep 23 09:43:44 2020

So, for the above extension (101) it will be removed from the memory only after 3548 sec, even if I killed manually that connection and the softphone it's not replying anymore to the keepalive options. By using the keepalive_timeout function from the nathelper module - it's working fine.
Regards, Ilie.

Hello, have you watched for how long it stays in memory? The usrloc keepalive should leverage the same mechanism that was used by the keepalive done by nathelper module, it should not delete the record immediately, but after ka_timeout elapsed from the last received keepalive, then expires is set to current timestamp + 10 seconds, so the next timer cleanup should remove with. Can you get the kamctl up dump for the phone you tested with? The keepalive related attributes (last keepalive timestamp, last rtt) should be in the json output/ Cheers, Daniel On 23.09.20 00:13, Ilie Soltanici wrote:Hello, Tried with the latest 5.4 branch, but ka_timeout still not working for me, the record it's still available in ul.dump even if that extension is not replying anymore to the Options sent by the 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 On 22.09.20 19:17, Ilie Soltanici wrote: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"?
