    The CPR Call Blocker uses the ‘first ring’ to get the Caller ID signal and then checks this against the block list to see if the number has been blocked – it is however designed to ‘mute’ this first ring so you should not hear a ring if caller is a blocked caller

    If you’re hearing a single ring, this could be due to a couple reasons, ranging from the set up of the CPR Call Blocker, the location the CPR Call Blocker is connected on the phone line, the telephone(s) make/model that are plugged in on the line, the line running to the property or the line provider

    The first thing to try is to have JUST the CPR Call Blocker and ONE phone connected and remove any splitters/filters/extension cables in use – if this resolves the issue, the issue is either the other phones/cables in use or the location the CPR Call Blocker is connected in relation to the other phones – re-connect the other phones one at a time to see which phone causes the single ring issue – when you have identified it, try connecting the CPR Call Blocker at this point or disconnecting this phone entirely

    If this doesn’t resolve the issue try connecting the CPR Call Blocker and the single phone to each of the telephone sockets in the property until the single ring issue is resolved, it is best where possible, to have the CPR Call Blocker connected to the first socket/jack on the circuit

    If you plug into the first socket/jack on the circuit and still have the singe ring issue, try using a different make/model telephone in with the CPR Call Blocker

    If you still have the issue after each of the steps described, the issue is likely the physical line itself or the line provider which we unfortunately cannot resolve
