You do not need a telephone line to have any sky plus or hd box,on many occasions people and sky tell you that you need a phone socket and this is absolute rubbish.
All updates and firmware upgrades are sent via the satellite dish and the only reason you would want a telephone line connected is for the interactive services and pay per view trash that is on Sky.
I have 2 hd boxes in our house and one sky plus box and not one of them are connected through a telephone line even though i have sockets right on the wall next to them.
Sky will always tell you that you need a telephone socket and its just not true and another way for there contract sky engineer to make money.
Sky contractors in my experience are shoddy at best and there work leaves a lot to be desired.
And many isp will tell you that interactive phone lines ftted by sky,bt or anybody else are to blame when you have problems with your adsl connection.
I have lost count of the number of occasions when i have contacted my isp over the years about Internet problems only to be told the first thing i must do is remove all sky interactive phone lines from the sky boxes because this can cause problems.
Don't know how true this is but its what many isp will tell you to do should you encounter Internet problems or connections trouble.
My advice for you would be to tell sky you are having a phone line connected soon and do not let them do work that is not required.
They do not need a phone line to activate the sky box [they may tell you otherwise] they can just make a phone call.
I moved in to a new house recently which had no phone lines activated,when ordering the home move i was told by sky that i needed interactive phone lines fitted before they done the job ...When they came out and put the new dish up i just told the guy i will sort out the phone lines when i am ready because none of the sockets were active because having to wait weeks for that terrible company called BT to flick a switch and charge us £130 for what they call a new connection at a new house...
And 6 Months later as i stated not one of the 3 sky boxes in our house has a telephone line connected to it.
