No, it really isn't. "Create a contact for yourself in your account"? Do you just mean like adding new contacts or are you trying to add yourself as a contact on your own account (that's what it sounds like
).
Rereading your original post though, I guess I understand it now. It feels like when I use Skype and my fiancee is also signed in, then if I her profile goes active and I go to skype again, it changes to her skype. She has never got a skype call there though, so I wouldn't know if they come through even if you account isn't active, but I suppose they do since you say it's the problem.
The easiest solution would be to sign yourself out, I can't figure out any other way to not have your profile ring too when they call you.
Or they could just reject the call coming to you using the controller? Not sure though if it's possible without actually opening Skype (and then it would switch the skype profile again..). It's a bit silly when I'm at home and someone Skype-calls me and I have 4 devices ringing here
