    I seen there is a plug in for this on Max2Play. So I looked it up. It would be real nice to block calls. I know when I 1-800 call comes in it’s all ways some one trying to sell you something.

    How does this work with Mas2play? I guess it knows from a IP the tellows call blocker get?

    Do it work with a real phone? We have a real phone still and a google voice here with a obihai box.

    Looks like this tellows cost about $100.

    Just want to see how it would work. Would the plugin for Max2play display the caller ID on the Max2play screen?

    OK I can see we have the Max2Play software and call blocker module installed on a Pi BUT what other hardware is needed to attach this to a telephone. Is it a PBX solution or will it connect up with a normal house phone with standard telephone jacks. This sort of information seems to be lacking and is preventing me from deciding if I want to try and build a system.

    Can the CallBlocker handle multiple numbers? I’m using 4 SIP numbers on my FRITZ!Box.

      Hello Holger, yes, in the Fritz!Box you can set the blocker as an additional phone and choose for which of your numbers the call blocker should be activated.
