TalkTalk says it’s seen a “four-fold” increase in the number of customers signing up for its landline privacy features since making them free last month.
In January the ISP and phone company axes charges for its last caller barring and anonymous caller reject features.
Its 4 million phone customers already had free access to Caller Display, 1571 Voicemail and Withhold Your Number.
A spokesperson says the increased sign-ups “reinforces TalkTalk’s view that nuisance calls are a serious matter, which more telecoms companies should act upon.”
They added: “These services build on TalkTalk’s nuisance call reporting and blocking service launched in October 2013. Customers can report spam or persistent sales calls to a dedicated expert team who are able to block the number at a network level, thus stopping them reaching all TalkTalk home phone customers.”
