Not authorized user trying to register to my asterisk Sip Server

Hi all,

I have an asterisk server and for some reason random users are trying to connect to it, and these people don not have extension set up and they are not a sip user in my server.

The issue is when I get to the command line by typing asterisk -r I never get the prompt, all I see is a bunch of messages like the ones below and I can never get to the prompt. this keeps scrolling acros the screen.

As you can see, this user Jacob does not exist in my server.

Any help is appreciated.

Thank you!

Rone
