Detect and block spam phone calls
Is a link to a web based manual page really useful and noteworthy?<p>I don&#x27;t silence unknown callers on my home land line - I put up a very simple IVR.<p>Interactive Voice Response, an IVR is a set of prerecorded voice prompts linked to a set of key presses which might perform actions, you&#x27;ll know what I mean by the following:<p>&quot;Please press 1 if you think we would like to talk with you; 2 to leave a voicemail; If you are making an unsolicited sales call then please hang up.&quot;<p>I chose the words quite carefully to be quick and get the message across.  The initial please is to give you an extra tiny amount of time to understand what is going on as well as being polite.<p>We don&#x27;t get much voice spam on our landline.  To be honest - none that I can remember. Landlines are less of a target these days I think.  Ours basically screws with auto diallers which seem to be the bulk of spam callers, that try to detect a person answering and hand off to an agent.<p>If I can manage that on my own landline surely a trillion dollar company can manage something far fancier for their customers.<p>&quot;Turn on Silence Unknown Callers&quot; is a bit rubbish - it&#x27;s only an allow list.  I do that too and deny lists but the IVR is the real filter.<p>An allow list (which would have been called a whitelist) is soooooo 1990s!
