Device with IP Authentication is asked for Username/Password

• In Device settings:
  • Enter correct IP in Host/IP Address field
  • Make sure there is no password entered
  • Mark IP Authentication = YES
  • Mark Trustrpid = YES, Insecure Port: YES, Insecure Invite: YES

Retry dialing.

If it does not help and system still asks for username/password - get sip debug for the call.
