Its cheaper to buy a mobile phone on contract that can block unwanted calls, than it is to pay for line rental. U could also tether it to the wall with a length of string of u want to give it that "BT home phone" look
IMO, the more they up the line rental, the more customers they loose. Im on Virmin but have the internet. I haven’t payed line rental in years. VOIP !
