Hi Sir/Madam,
I'm trying to set up the presence service according to the manual http://kb.asipto.com/kamailio:presence:k31-made-simple

Also refer to the doc https://kamailio.org/docs/modules/devel/modules/xcap_server.html

Seems the Kamailio cfg fine.  but when to get the xcap data, get the 401 response.

Please see the attached log. Is there any more should be configured?

Thanks!

BR,
Sparkle Zou
