[asterisk-users] how can I get authenticate from my own server?

[Sean Darcy]

I'm  used to seeing fraudulent attempts to authenticate, But now I'm 
getting them from the server itself.

I have an asterisk server behind a firewalled router. The local subnet 
is 10.10.10.0/24, the server is 10.10.10.100.

Now I'm seeing in the log lots of:

Failed to authenticate device 
<*>00<sip:<*>00 at 10.10.10.100:5060>;tag=9c565e6e

How can this happen?
