The credentials he uses to sign into his Cox account in order to view call history are the ones to which I was referring. He has never had a Cox email account. My Call History failed a couple of times a few years back, but has worked fine during the recent issues people have reported
As you correctly stated in a previous post, call history is retained. But, for some reason, it's just not currently available for the OP to view. One possible reason could be an authentication issue with Call History. Clearing his cox.com cookies to force re-authenticating with his Cox credentials might cause a reset. But, even if it doesn't fix his issue, he would be no worse off than he is now.
