I have problems adding a new location by RPC command.

# kamailio -v
version: kamailio 5.5.0 (x86_64/linux)

id: unknown
compiled with gcc 8.3.0

A simple example, adding an AOR which expires in 1 hour:

 

# date ; kamcmd ul.add kam_location 1002-test1@sipserver.com sip:1002-test1@192.168.89.82 3600 0.0 . 0 0 0 .
Wed 08 Sep 2021 01:58:00 PM CEST


Location record has been inserted correctly:

# date ; kamcmd ul.dump | grep test -A24

                                                }
                                        }
                                }


But a few seconds later, the location record has gone:

# date ; kamcmd ul.dump | grep test -A24

In kamailio logs I can see that:

What am I doing wrong? It is supposed that the connection is by UDP. I also tried to insert the socket value as UDP, but it had the same problem.

Thanks!
