Review on 🚫 CPR Call Blocker V2000 - Advanced Scam Number Blocker with 2000 Pre-Programmed Scam Numbers and Capability to Block 1500 Additional Numbers Instantly. Caller ID Service Essential for Optimal Use. by Kevin Taharka

Like some others, I really wanted the CPR V5000 to like it, especially since it had so many good reviews, but it does have some obvious flaws. I'm an Electrical Engineer with 40 years of experience designing complex commercial, industrial and defense electronics, so configuring or troubleshooting electronic equipment is a breeze for me. When the standard setup didn't work (Caller ID was transmitted periodically from the base station to my DECT cordless phones), I connected the device using the parallel setup. While the device broadcast caller ID to all remote phones; When dialing a number, the device's display is completely off, as if the minimum operating voltage is not present. and the outgoing number was not displayed. I measured the voltage on my phone line at several places in the house, including the line that connects to my base station. All locations comply with FCC Part 68/TIA-968-A voltage ratings for both on-hook and off-hook conditions. However, the flaw that completely scuppered the deal was the inability to block calls that show "Out of Area" in the caller ID while still showing the area code in the phone number. There are other brands that do this as well. Also, having 5,000 landline numbers is only good as long as scammers and telemarketers keep using those numbers. Eventually these numbers will become obsolete and the only way to expand the usefulness of this type of device is to either allow threat phone numbers to be updated regularly, or provide sophisticated programming modes to cover known possible caller ID name and phone number variations. While the CPR V5000 was easy to set up and use, it didn't offer a solid lock that met my needs, so I returned it.
