Telephone Landline Caller ID and Spam Calls Blocker Description
There's nothing worse than picking up the receiver and having to talk your way out of yet more hassle. This phone line blocker might well be your answer - it gives you an immediate caller ID on the LCD screen, and lets you block nuisance numbers from reaching you again at the touch of a button.
Capable of blocking up to 1,500 numbers, or up to 10 entire area codes, this spam call blocker will help you get some peace of mind back over your landline phone use. Better yet, it works on outgoing calls too - so it's not just incoming caller ID blacklist capabilities at your fingertips, but more control over phone use overall.
For instance, if there are members of your household dialling up expensive numbers or making calls you'd rather they weren't, this phone line blocker can prevent that. It's powered by the phone line itself too, so your spam call blocker is consistently powered up - no batteries to run down.
Alongside these caller ID blacklist capabilities, this device also helps you with record keeping. Because it stores the 50 most recent dialled out numbers and the 100 most recent received numbers, you're able to trace who said what to whom and when - hugely useful, and another feather in the cap of a remarkably handy phone security machine!
