Step 3: Select the Block Call Option

In the menu, choose the option to block calls. The option may appear in different forms, including “Call Block or Nuisance Call Block” or something similar in that line. Choose this option once identified.

How do I block incoming calls?

You can block calls on your Panasonic cordless phones using the “incoming call barring” feature. Some individuals know this feature as a “Nuisance call block.” If you do not want to receive calls from specific numbers, the “incoming call barring” feature enables you to reject the calls you do not intend to answer or the junk calls.

However, registering them in your Panasonic phone unit is the first step in rejecting these calls. If the incoming call number matches the entry in the call barred list, your cordless phone will emit no sound to the caller, and the call will be immediately disconnected. One essential element with this feature is that you only need to program the setting with one handset. If your device has five connected handsets, only one configuration will do for the other.

You can register a phone number in the call-barred list following two approaches:

The first approach is to register the phone number after they call you.

  • Open your caller list.
  • Select the entry you want to be barred
  • Select “Save CID.”
  • Select “Caller Barred”

Thus, we should add the number to the call-barred list.

The second approach is entering the phone number manually.

  • First, navigate to the Menu-Initial setup-call barred
  • Determine and enter the phone number you want to add to the call-barred list manually
  • Select “OK.”

This should help add the number successfully to the list. However, remember that Panasonic cordless phones have a user manual that you can refer to for specific instructions. Also, you should note that the call barred list can contain up to 50 numbers.


For your call barring feature to work, your phone must meet certain requirements. For instance, ensure you have subscribed to a Caller ID service. The service will allow you to receive information about the caller’s phone number to enable you to block it. You can contact your telephone or service provider for details on the subscription to the Caller ID service.

Secondly, it is important that the feature “First Rinf” is turned off. To turn off this feature, go to the Menu, Ringer Set Up, and click Off. Turning the ringer off ensures that your phone does not ring before receiving caller information.

How does Panasonic Nuisance call block work? 

The Panasonic Nuisance call block feature can be operated manually and automatically, allowing you to block unwanted calls. The function works by checking incoming calls for caller ID information. It allows you to add a given number to your phone’s block list  and rejects subsequent calls from the number.

The call block feature can be operated both manually and automatically. In manual operation, you add numbers to your block list by entering the caller’s number into your phone’s settings. However, in automatic operation, you use the Panasonic Nuisance Call Block database to block nuisance calls. The database incorporates different callers, including unwanted calls, scammers, and telemarketers.

However, you must have a Caller ID service to use the Panasonic Call Block feature. You will get this service from the Panasonic Company or your phone company. Once registered to the service, you can enable Panasonic Nuisance Call Block in your phone’s settings.

You can use the function following the below process.

  • Locate and press the menu button on your Panasonic cordless phone.
  • Choose settings function
  • Choose phone settings and select the Call Block function
  • On the Call block function, choose block a single number in case you intend only to block a specific number.
  • Add the number by entering the 10-digit number.
  • Save and press the enter button to add the number to the block list.

By this, any future calls from the blocked number will be rejected. The crucial element of this feature is that you can unblock the number by following the same procedure but choosing the unblock number or call option.

Ultimately, the Panasonic Nuisance Call Block provides an excellent way to eliminate or avoid unwanted or nuisance calls by allowing you to add the numbers to the block list and reject the subsequent calls from the numbers. The function is easy to use, and you can customize it to suit your needs.

What to do if the “incoming Call Barring” function Fails to Work

The “incoming Call Barring” feature blocks or restricts incoming calls from given numbers or callers. You can use the function to control the calls you receive from your Panasonic cordless phones by preventing nuisance or unwanted calls from reaching you.

Besides, you can enable the incoming call barring feature from specifying given criteria for the calls you want to block. The approach may include securing calls from given callers, anonymous or private numbers, international calls, or calls from given area codes.

Thus, you can effectively filter out unwanted or nuisance calls and maintain your privacy using the incoming call barring feature. The function helps reduce disturbances like spam calls, telemarketing calls, or calls from unfamiliar sources. With this feature, you reduce interruptions and ensure you only receive calls from the people you want to interact with.

However, despite its importance in eliminating interruptions and barring unwanted calls, sometimes it can fail to work and put you in situations where you must interact with unwanted calls or even spam and telemarketing calls. This could be unpleasant, especially when certain crucial activities preoccupy you. Do not fret!

If your Panasonic cordless phone’s “incoming call barring feature” does not function, it could result from the below causes. Also, try the accompanying troubleshooting tips illustrated below to solve the problem.

  1. The problem with the incoming call barring function may arise when you haven’t subscribed to the caller identification service with your service provider or when the call has originated from an area without the caller identification service. Also, the problem may occur when your caller uses a private number. Check for the subscription; if not on the service, contact the providers to be subscribed.
  2. No Compatibility- your Panasonic cordless phone model must be compatible with the incoming call barring feature for the function to work. First, you must assess the compatibility of your phone model with the feature. For instance, some older phone models do not have the functionality. You must double-check the specifications or consult your user manual to determine whether your unit has the feature and its compatibility with your phone model.
  3. Wrong setup. Secondly, not correctly setting up and activating the call barring feature may affect its functionality. Use the instructions manual to follow the procedure of setting up the Panasonic phone and the call bearing feature to ensure the setup is appropriately done and the feature is activated. For instance, guarantee that you use the correct codes and buttons when enabling the call barring.
  4. Power cycle the phone. Sometimes the call bearing feature may not work due to power issues at the base unit. So, try to turn off your cordless Panasonic phone and unplug the base station from the power outlet. Take some minutes before you plug it back in and turn it on. The goal is to refresh the system and resolve any momentary glitches.
  5. Try performing a factory reset if you have tried the above troubleshooting tips for a malfunctioning income call barring feature. The only challenge with this practice is that it will erase all the custom settings and data. Back up any essential information beforehand so you do not lose important data from your phone. Consult your manual on factory resetting your phone; the process may vary based on your model.
  6. Lastly, you can contact Panasonic phone customer support to help with the issue if you have tried the different approaches and failed.
