Caller ID Verification and SHAKEN/STIR FAQs

What is SHAKEN/STIR? 
SHAKEN/STIR stands for Secure Handling of Asserted information using toKENS / Secure Telephony Identity Revisited. This is a solution mandated by the Federal Communications Commission (FCC) that uses digital signatures to authenticate the source of phone calls. SHAKEN/STIR is intended to increase trust that the information on a caller ID display is accurate and is not being misrepresented or spoofed.  
 
Does magicJack for BUSINESS use SHAKEN/STIR? 
To help address the growing amount of fraudulent robocalls, magicJack for BUSINESS has implemented SHAKEN/STIR caller authentication technology that uses industry-wide call verification standards. SHAKEN/STIR intends to combat caller ID spoofing which is used by robocallers to mask their identity or to make it appear the call is from a legitimate source.  
 
How does SHAKEN/STIR work for magicJack for BUSINESS? 
For calls that come into the magicJack for BUSINESS network, caller ID details may either indicate “Scam Likely” or “Verified.” The “Scam Likely” or “Verified” indicators will be displayed in the caller ID details when receiving calls using the magicJack for BUSINESS mobile app, desktop app, and compatible phones with caller ID displays.  

The caller ID details will normally indicate “Verified” for calls that pass SHAKEN/STIR verification standards. If you receive a verified call from a phone number that is already entered in your address book, it may simply display the caller ID (without being indicated as “Verified”.) 

Calls that fail the SHAKEN/STIR standards will be marked as “Scam Likely” in the caller ID display. When you receive a call from a phone number entered in your address book, it may still indicate “Scam Likely” if the originating source fails verification.

NOTE: Some carriers may not yet support or are unable to provide SHAKEN/STIR details. As a result, some calls may not have "Verified" or "Scam Likely" indicated. 

Why are incoming calls marked as Verified? 
The caller ID details will normally indicate “Verified” for properly authenticated calls that come into the magicJack for BUSINESS network. This simply means that the caller ID details are accurate and are not being misrepresented or spoofed. 

If you receive a verified call from a phone number that is already entered in your address book, it may simply display the caller ID (without being indicated as “Verified”.) 
 
Why are incoming calls blocked or marked as Scam Likely? 
Calls that come into the magicJack for BUSINESS network that fail SHAKEN/STIR standards will be marked as “Scam Likely” in the caller ID display. If you receive a call from a phone number entered in your address book, it may still indicate “Scam Likely” if it originates from an unverified source. 
 
Does SHAKEN/STIR apply to SMS/text messaging? 
Currently SHAKEN/STIR applies to phone calls only. However, work is on-going in the communications industry to evaluate the best authentication method for SMS / text messaging. 
 
What Caller ID information will I see for incoming calls? 
magicJack for BUSINESS displays the phone number of the person calling you. Caller ID Name (CNAM), which displays the name associated with the inbound phone number, is not currently a supported feature. 

How do I filter Spam/Scam incoming calls to my magicJack for BUSINESS number? 
Calls that originate from an unverified source may be marked as “Scam Likely” in the caller ID display. You can choose to ignore (not answer) or add them to your block list. 
   
Similarly, if you have enabled voicemail via email, the subject line of the voice email will also indicate either “Scam Likely” or “Verified” to help you filter the email messages more easily. 

If you experience issues receiving incoming calls from a specific number, make sure to check your Call Blocking settings. To report any inbound call screening/blocking issues, please send an email to callblockingerror@magicjack.com for investigation. Be sure to include the date and time of the call with the phone number that was dialed and the phone number that it was dialed from.
