Hi William,
Thanks for your feedback.
You should not hear a single ring when a blocked caller tries to call you, if this is happening, you will need to change one of the settings on the call blocker.
To do this, you will need to follow these steps :
1. Get a dial tone.
2. Press and hold the "Call List" button until you see the number 100 on the screen of the call blocker.
If you are still getting the single ring, then you will need to change the call blocker to it's second operating mode, to do that :
1. Get a dial tone.
2. Press and hold the "Call List" button until you see the number 200 on the screen of the call blocker.
If you still get the single ring, you will need to put the call blocker in it's third operating mode. To do that :
If you are still getting the single ring, then you will need to change the call blocker to it's second operating mode, to do that :
1. Get a dial tone.
2. Press and hold the "Call List" button until you see the number 300 on the screen of the call blocker.
One of these settings will solve the problem for you.
You can also block area codes or country codes, by following these steps :
1. Get a dial tone.
2. Press and hold the "Block Now" button until you hear a beep.
3. Enter the code **7# area or country code to block #
4. Hang up the phone.
