Have you enabled [PJ]SIP debugging? Bumping up console debug and verbose 
levels may also yield clues.

tcpdump+sngrep are my 'gotos' for packet analysis, but this may not need 
too much depth.

https://en.wikipedia.org/wiki/List_of_SIP_response_codes#:~:text=401%20Unauthorized,1%5D%3A%E2%80%8A%C2%A721.4.2

"401 Unauthorized The request requires user authentication. This response 
is issued by UASs and registrars.[1]: §21.4.2"

My guess would be a user or password mismatch.

Are you using SIP or PJSIP?
