Dave its just a radio answer phone, has a base phone with two slave phones, and has the filter function it was not any dearer than another similar phone got it years ago there is no subscription, its the software in the phone that filters the calls.. I got the name wrong it is Guardian not Sentry. Think it was about £60 for the three phones, I thought it good value. But I do agree there are far two many spam/scam phone calls made nowadays which the service provider should be stopping coming through.
