FRITZ! Box 6690 Cable
I have just received this router. I know from various forums that I can only operate it as a "2nd router", which also works. I have also bought 4 FriztFon C6. But now I can't manage to use them because I can't enter the phone number. I was told by UPC that I can't use this phone via VOIP either, because I don't get the password. Now, of course, I ask myself why I can buy this FRITZBOx in Switzerland at all if I cannot use most of the features in Switzerland? Do I have to return the phone or is there a solution with UPC/Sunrise, Sipcall or possibly another provider?
