[Freeswitch-users] Warning messages?

[Malay Thakershi]

Hello,

I get these messages on FS prompt. They seem like warning messages (purple
color).

2013-03-21 16:03:50.795593 [WARNING] sofia_reg.c:2376 Can't find user
[504 at IP.IP.IP.IP]
You must define a domain called 'IP.IP.IP.IP' in your directory and add a
user with the id="504" attribute
and you must configure your device to use the proper domain in it's
authentication credentials.
-----------

id keeps varying. What does this mean? Can any one help me understand? What
triggers this?

Thanks.
