Trouble with DID Provider

I am having a bit of trouble with my new DID number. My provider setup this for me and have pointed the number at my account. My asterisk server seems to be seeing the call come in but I only get this message at the CLI console:

Aug 6 19:03:45 NOTICE[69299]: chan_sip.c:10515 handle_request_invite: Failed to authenticate user “3053292283”;tag=as6a676392

Does this mean I’m failing to authenticate with them or are they failing to authenticate with me?
