I will be moving house soon and the current owners have Sky TV/Phone/Broadband. I do want Sky+ but unsure about phone/bb, would moving back to BT and another ISP be better (can use my existing router).

1) How long will it take to be connected to phone/bb with Sky?

2) What router will be supplied?

3) Is it possible to access my IP cameras and use VOIP/DECT function on the supplied Sky router? (currently using Fritzbox Fon WLAN 7170)

4) If I moved to BT and another ISP, how long would this normally take?
