Looks like my question was not clear enough.
What Verizon offers to its landline customers is a service that allows the customer to screen calls. A caller must either input a code number give by the subscriber or else state a name. The subscriber phone rings and if the code is correct, the caller is connected. If a name was given, the caller is on music hold and the subscriber hears the name given and may elect to block the call, put it in voice mail or answer. With the increase in unwanted calls for car warranties, surveys, etc., such a service is invaluable. AT&T offers it also to its land line customers and calls theirs Privacy Manager.
Does Verizon plan to offer this to Hub customers?
