What does that IP mean to you? Is that a node on your network? The logs are clearly showing that IP 192.168.20.194 is trying to register with 2000004755 as the authentication username. Is your issue that you don’t know who it is or that you can’t get an extension to register?

This isn’t a user name; it is an invalid domain name. User names are always followed by “@” and a domain name or IP address. I don’t think chan_pjsip can do domain only matches. (I think chan_sip had a bug/feature which caused it to treat an a isolated domain without a user as though it were a user.

Yeah… sip:2000004755 is going to get treated as a domain without a username.
If 2000004755 actually resolved to an ip address AND you had an “identify” section configured in pjsip.conf to match, you’d not see the message. Otherwise, since username is empty, we can’t match to an endpoint.

However, just because you see this message the request could still succeed. If an endpoint has auth_username in its identify_by parameter and has an associated auth defined, a 401 response will be sent with the challenge and if the client responds with the correct credentials, the request will succeed.

Oops…I was incorrect. We don’t use the domain for identification. Not sure what I was thinking. Sorry.

So, that error message is (I think) pretty clear.

First question: is 2000004755 the name of an endpoint which you believe should
be allowed to register to your Asterisk server? If so, please show us the
relevant sections of pjsip.conf for this endpoint.

Second question: is 192.168.20.178 the IP address of a known and trusted
device such as a telephone or soft phone on your network?

Antony.

It may not seem obvious, but (6 x 5 + 5) x 5 - 55 equals 5!
