Robocalls are a plague, and many people are unwilling or afraid to pick up their phone unless they know the caller. Waiting for a job interview or a support call back is incredibly stressful ̵
New standards will remove spoofing
If you have a T-Mobile service and a Galaxy S9, you will do so soon When calls arrive, "Caller Verified" will be displayed when T-Mobile can verify that the Caller ID matches the actual phone number. The message Caller Verified means that the call came from T-Mobile and he can confirm that there was no spoofing or intercepting during call creation.
Call screening depends on a new standard known as Secure Telephone Identity Revisited (STIR) and SHAKEN (Signature-based Handling of Confirmed Information with toKENs). STIR / SHAKEN is not to be confused with the instructions for preparing Martini. With STIR / SHAKEN, phone carriers can determine if the number a call is identifying with is real. The current caller ID technology does not have a method to determine if the information provided is correct, and STIR / SHAKEN will solve this problem.
And as other operators implement STIR / SHAKEN, they work together so that verification of calls even occurs when they come from another carrier.
In addition, T-Mobile, Verizon, and others already offer blackmail-based blocking services. The blocking of Robocaller has been free of charge at AT & T since 2016, and since the beginning of 2017 it's free of charge at T-Mobile. Verizon has now announced that call screening will no longer be charged from March.
You may already have some spam blocking
Crowdsource-based spam blocking software is already ubiquitous, and you can either subscribe to it from your wireless service provider or download an app for your phone that achieves the same goal However, new STIR / SHAKEN standards will take longer.
If you have T-Mobile and a Galaxy S9, you now have the first steps in technology, and "more devices" will get STIR / SHAKEN in 2019 in the meantime Verizon and AT & T have promised to implement an exact timetable for the period after 2019, but without a gen Schedule a schedule. Sprint has made no such promise and instead questioned the cost and effectiveness of plans to assist in the implementation of the standard. Microsoft supports SHAKEN / STIR and helped with the development. While they are no longer working on Windows Phone, they have an interest in Skype.
STIR / SHAKEN is similar to HTTPS
When STIR / SHAKEN is installed, a call is made first Add a certificate that verifies the number assigned to the signal. During propagation, this certificate is validated with an encrypted repository. If everything matches correctly, the service marks the call as confirmed. If this is not the case, the carrier knows that the number of potential spoofing is.
What the phone companies will do next is their decision. If necessary, you can mark the call as confirmed or display a possible fraud message or block the call.
If that sounds familiar, it's because the process is very similar to using secure certificates in web browsers. This also shows a significant disadvantage. Just as a security certificate does not mean that a website is secure, a confirmed caller message does not show that the call is not a robocaller.
If the robocaller calls from a legitimate number he bought without spoofing, then The call is displayed as confirmed. Hopefully crowdsourcing lists and blockages at this point will finally be useful as the robocaller does not change his number every time he calls.
How to block spam calls now
If you do not want to use a Galaxy S9 on T-Mobile and do not want to wait for Verizon to download their Free service, there are options that you can use today. You can subscribe to Verizon's call screening service until it is released by Verizon.
You can join the call log, which is worth it – which does not seem to be much these days – and lock the numbers one by one. On iPhones, you can download an app like Hiya, which stores crowdsource blacklisting scams that you can then tag or block. On Android, you have built-in options, and you can also use a similar app like Mr.Number or TrueCaller.
These crowdsource blacklist apps can unfortunately block legitimate calls. Remember, if you frequently receive calls from unknown numbers.
This is just a measure of peace
. Unfortunately, the actual freedom from spam calls completely depends on the operators to solve the problem. So far, they have been more than willing to enforce these demands and blame other and existing laws.
The FCC asked them to, and that made a difference. But until the cost of fraud calls is higher than the profits made, callers will continue to try and hope that you answer. Until better solutions arrive, ignore the calls best.
