BT has launched three new products to help consumers block nuisance phone calls.
UK households can use the new phones - BT7600 Nuisance Call Blocker, the BT4000 Big Button and the BT4500 Big Button - to reduce the number of unwanted calls they receive.
BT says the handsets allow landline customers to reduce the number of nuisance calls by 80 per cent, by blocking calls from 'international', 'withheld' and 'unknown caller ID' numbers.
Research from Ofcom suggests consumers receive on average two nuisance calls per week, with live marketing (38 per cent), silent (34 per cent) and recorded sales calls (14 per cent) most prevalent.
John Petter, Consumer Managing Director at BT, claimed the firm takes this issue "very seriously" and is constantly looking for ways to help customers manage their calls.
He noted that the BT6500 phone - which launched with call blocking features in March 2013 - has proved "a big success" and quickly become BT's biggest-selling handset.
And with this in mind, the service provider is expanding its range of nuisance calls phones to offer peace of mind to even more customers.
Mr Petter said that when the phone rings, it should be someone the recipient wants to speak to.
