[SR-Users] Kamailio strange behaviour

[Daniel-Constantin Mierla]

You can always replace the real IP (and usernames/phone numbers) with
something else using a text editor, before posting to the mailing list.
If no details are given, it is hard to help.

Anyhow, in this case you provided some leads, respectively that you get
401 response. That could be because the password was wrong. You can run
kamailio with debug=3 and see what is printed when the phone fails to
register or use xlog() to print $rc after auth_check()..

Cheers,
Daniel
