Tired of nuisance or unwanted sales calls? Put an end to them quickly, easily and permanently with the Pro Call Blocker.

Block all unwanted calls at the touch of a button. If you’re fed up of being pestered over the phone, the Pro Call Blocker offers a complete, all-in-one solution that’s capable of blocking any nuisance caller.

Put a stop to unwanted calls from:

  • Telemarketers
  • Charity and nonprofit organisations
  • Research companies conducting polls or surveys
  • Collection agencies, banks, lawyers, hospitals and credit card companies
  • Malicious callers


How Does it Work?

Once you’ve received your Pro Call Blocker, setup us simple. It takes two minutes to plug the call blocker into your phone socket, and plug your telephone (with Caller ID enabled) into the unit. You’re now ready to add unwanted and nuisance numbers to the device’s Blacklist.

With an easy-to-read backlit LCD screen, you can quickly see who’s calling – and if you don’t recognise the number, you can manually add it to your Blacklist with the touch of a button.

Add a number to the Blacklist. The next time that caller’s number is recognised, all the caller will hear is a dead line. You won’t hear anything at all. The call blocker silently handles nuisance calls each time they attempt to get through to you, leaving you free to spend your evenings in peace.


Excellent Call Blocking Functionality with No Extra Cost

The Pro Call Blockers gives you complete blacklist flexibility. Unlike other call blockers which come pre-programmed with around 200 of the most common numbers, you’re free to add up to 1,500 nuisance numbers (which you can remove at any time), making it the perfect tool for putting an end to irritating or malicious calls.

Find a permanent solution with no ongoing costs. The Pro Call Blocker takes its power from your phone line, so you won’t need to think about replacing batteries – and, unlike the phone screening services from most telephone providers, it’s completely free to use, with no monthly charges.


Pro Call Blocker Features:                                      

  • Simple setup and easy to use – store telephone and fax numbers in ‘Blacklist’ with the press of a button
  • Large memory capacity, capable of storing up to 1,500 numbers
  • Battery free – it takes its power from the telephone line
  • Works worldwide – suitable for use on all analogue phones and most VOIP lines (including Vonage, Comcast and MagicJack)
  • Works with FSK/DTMF dual systems (requires Caller ID service)
  • Blocks numbers with up to 16 digits
  • Easy-to-read LCD display with 4 levels of adjustable brightness
  • Uses EEPROM technology to prevent losing stored blacklisted numbers when device is disconnected from the telephone line


Avoid unnecessary and unwanted telephone disturbances and block nuisance phone calls permanently. Order the Pro Call Blocker today.

    Unfortunately the Call Blocker didn’t work on my telephone system but for anyone who is concerned about trying it,do so! If it doesn’t work the return and refund was a very simple smooth transaction. I would certainly recommend Many thanks!
