Hi Daniel,
First of all, thank you for your help!
Below you can find more detailed info:
I have following infrastructure:
22@10.50.210.9:6574 - UAC 11@10.50.210.9:50365 - UAC
10.101.237.133 - Loadbalancer Kamailio 10.101.241.55 - Kamailio Proxy, where UACs are registered
So this is how Invite travels
Invite (1)22@10.50.210.9:6574 => 10.101.237.133 - Loadbalancer Invite (2)10.101.237.133 - Loadbalancer => 10.101.241.55 - Kamailio Proxy Invite (3)10.101.241.55 - Kamailio Proxy => 10.101.237.133 - Loadbalancer Invite (4)10.101.237.133 - Loadbalancer => 10.101.241.55 - Kamailio Proxy 407 Error (5)10.101.241.55 - Kamailio Proxy => 10.101.237.133 - Loadbalancer
So invite get stuck at LB 10.101.237.133, it should send invite to 11@10.50.210.9:50365 at step (4) but it sends to Proxy back instead. After this proxy replies with 407 error.
Please find full SIP trace in attachment.
Thank you!
With kind regards,
Jurijs

So basically extension 100 sends invite to LB, LB then send invite to Kamailio server and Kamailio server replies with 407 error.
Do you have any ideas why?
No, you'll have to debug this the usual way. Run kamailio at a highe debug level to see what it is doing and log queries to the database. You'll have to make captures to see how the flow op sip messages is and who is requiring authentication.
Maybe you can give me more details about config on Kamailio server behind LB?
The config is equal to standard in this regard. Show us your config for the backend regarding authentication and registration.
