I am new to Kamailio. I have a configuration with existing phones. I call between them.
However, I have a problem with the configuration of PRESENCE.
I guess I'm doing something wrong. Can someone send me a sample setup working.
I looked for a long time information, but I could not fix my problem.

In the logs I get the information:
6 (19259) ERROR: pua [send_publish.c: 578]: New PUBLISH and no body found-invalid request
6 (19259) ERROR: pua_usrloc [ul_publish.c: 326]: while sending publish
[cycle # 12, if constant make sure server lives]
