Blocking landline nuisance calls

[Ianhende]

How can I stop nuisance calls on my landline ?

[Mark]

Hey @Ianhende If these are unsolicited cold calls, you can block these by registering the Telephone Preference Service. For help stopping nuisance calls from other sources, check out our support pages.

Another way to do it is you can purchase phones which have the feature built in.

I know BT offer them and some models have extra features like announced calls for people who are not on contact list.
