Do sky boxes still require to be connected directly to a phone socket?
Only if you have multiroom--- fact
Stops people moving boxes from address to address and watch sky on the 2nd,3rd,4th viewing cards .
Phone line proves boxes location.
Single box isn't needed to be, only for interactive spend more money function or box office/on demand.
subscriptions are not reduced on a single card hence why phone doesn't have to be attached.
This answers the question .
My mum n dad had Multi-room and used to take one box on holiday with them in the caravan (my mum cannot miss her Tennis!) and both boxes worked fine, they did that for 4-5 years at least
They will still work, but if they were removing for holidays, coming home and reconnecting, the minute the box senses dial tone, it will call back Sky by itself.
Some people get away with it, but if they do, they take the risk of making each viewing card missing its scheduled call back a full charge debit from their bank account. Sky issue 3 warning letters before this happens.
They also monitor what's called Call back sequences, ie all boxes on a multi basis should reply 1 after the other. If they don't and one responds say a week later from the other, the customer is written too, and warned about charges etc.
You take the chance but if you do take boxes on holiday Repeatly, or be silly enough if abroad to phone in with a fault, the call centre pick up where the call is being generated from so be carefull.
