Even with caller ID, screening calls before answering them is a burden. Because of this, software developers introduced "call blocking" as an extension of caller identification. Here is some pertinent information about the current state of call blocking apps.
Call Block Apps
While caller ID displays information about the caller, it wasn't intended to stop those calls from occurring. Developers created call blocking technology to identify and stop calls from happening once specific criteria is met. These call blocking protocols exist between a third-party as calls are received. Phone companies or applications on your mobile device provide these services in the form of call blocking apps and call screening features. They recognize the source of an incoming call and allow or deny it based on your preferences.
Popular Call Blocking Apps and How They Work
Thanks to smartphone technology, software developers still make regular advancements in call blocking. There are now many applications that work seamlessly with your device to screen and block phone calls on your behalf. Here are some of the latest and most popular call blocking services available and how they work.
Hiya was initially developed as a reverse number lookup service, previously known as White Pages Caller ID. Currently, the application allows you to both identify and block unknown calls. They claim to analyze over three billion calls every month. Hiya aims to give users more information about the calls they receive.
This call blocking app automates alerts to your phone, warning you of threats. The software blocks marked calls without the need to review them. Also, this service extends to text messages. Lastly, you can manually blacklist numbers that don't appear on the Hiya block lists.
Automated robotic services make more and more calls these days. Nomorobo wants to put a stop to these unwanted calls. Actually, their high tech strategy won the "Federal Trade Commission's 2013 RoboCall Challenge." When Nomorobo detects suspected robot calls, it reroutes them and compares them to whitelists and blacklists. Finally, the caller must confirm they are human before the call goes through. This technology works on both mobile phones and landlines.
However, there are instances where a robotic call is legitimate. For example, automated messages may inform you of hotel bookings, shipping updates, or bank messages. Since Nomorobo's goal is to target malicious and unwanted callers, it makes provisions for these legit calls to go through.
Truecaller is another popular call blocking app trusted by millions of users. Its interface allows real-time updates to white and blacklists. Users see the names of unknown callers and get information about them at a later time. Sometimes it even makes sense to remove specific flagged numbers from your blocklist, so Trucaller makes this very easy to do.
The application organizes all of your call history, contacts, and preferences, and allows you to back them up to Google Drive. Lastly, Truecaller's database access enables blocking callers once other users of the software flag them.
The Difference Between Call Blocking and Spam Flagging
It's important to know that there is a difference between blocking calls and flagging them. Call blocking is normally for one-off scenarios and any number of reasons. On the other hand, spam flagging seeks to report fraudulent and non-compliant businesses to national databases. As more people flag a phone number, eventually it finds its way into call blocking services automatically. This automation lessens the workload of individuals manually creating block lists and helps promote better business practices.
Since this is the case, it's essential for businesses to continually monitor the integrity of their phone number reputation. This attention to detail ensures that the databases aren't inadvertently flagging them. Essentially, you're making sure people aren't accidentally missing calls from flagged numbers.
Call block technology is a necessity for both residential and commercial phone service providers. Take advantage of the latest call blocking apps, and you can quickly screen your calls. This screening helps you to minimize fraudulent and spam-related communications.
