[asterisk-users] SIP warnings (401)

[Geoff Lane]

Hi All,

Asterisk 1.4.12 on CentOS 5

Yesterday and today I got the following warnings in /var/log/asterisk/messages:

WARNING[2066] chan_sip.c: Got authentication request (401) on unknown REGISTER to '<sip:account at sip.voipuser.org>;tag=d8f15e1f30efddd35168b07dba9d540e.3922'

The corresponding bits in sip.conf are:

register => <account>:<secret>@sip.voipuser.org/<TelNo>

and

[TelNo]
type=friend
context=external
nat=yes
username=<account>
secret=<secret>
host=sip.voipuser.org
fromuser=<account>
fromdomain=voipuser.org
insecure=very
qualify=yes
canreinvite=no


Checking voip-info.org, I see that a 401 response means that the
requester is unauthorized, but I'm unsure whether that also means the
requester is not authenticated or even whether it's my VSP's server or
my Asterisk system that's returning the 401.

I've only used the number for incoming calls, which can still be made
to this number. However, I'd like to retain the ability to make the
occasional outgoing call via this service.

What do these warnings mean, do I need to worry about them, and how
can I stop them?

TIA,
