---------------------------------------

             Summary: Outbound SIP registration, if the auth object's realm option is not set to the same value as the 401's realm, then we fail to create a new REGISTER with auth details
                 Key: ASTERISK-22386
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-22386
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Resources/res_pjsip, Resources/res_pjsip_outbound_authenticator_digest
    Affects Versions: 12
         Environment: SVN-branch-12-r397614M (with patch from ASTERISK-22380)
            Reporter: Rusty Newton


Without "realm=<somevalue>" defined we see 

{noformat}
[Aug 25 16:57:54] WARNING[21069]: res_pjsip_outbound_authenticator_digest.c:90 digest_create_request_with_auth: Failed to create new request with authentication credentials
[Aug 25 16:57:54] WARNING[21069]: res_pjsip_outbound_registration.c:387 handle_registration_response: Temporal response '401' received from 'sip:gw1.sip.us' on registration attempt to 'sip:5279938664 at gw1.sip.us', retrying in '15' seconds
{noformat}

after the 401 in an outbound REGISTER dialog.

I'll attach a working and non-working example to make it clear. For Asterisk to issue a new REGISTER request with Authentication I had to define realm specifically with the value we see in the 401's WWW-Authenticate header.

I'd imagine that Asterisk should at least try a new REGISTER with realm's default of "asterisk" instead of ERRORing out.
