I set up my k175 a few years ago and got the newer model the other day and before I set it up I figured I'd log out and log back in on my current. I've tried my extension, email address as username, tried the password I set under user tab for my extension. I tried password set in the Telephony tab and I tried the admin password in settings file. none are working. What do I need to use for username/password to log into the vantage software on the phone and where do I set it? Thanks
