Are your calls being tokenized? Yes, your carrier says!  But wait, are your tokens being delivered to the carriers that count?  That is the question.

Most carriers are still playing catch up. They didn’t think SHAKEN was going to become a real thing and delayed doing the hard work. Now they downplay the importance to you & your answer rate, while they do the work to deploy SHAKEN to their network.

They say tokens won’t stop your calls from being blocked or labeled. By itself, this statement is true, but disingenuous. Worse, their delays have already impacted your answer rate.

How, you ask?

Yes, it is true that a large part of the nation’s telecom network is not yet 100% SHAKEN. The FCC has even given rural carriers 1+ years to get there. It is also true that Call Labeling & Blocking software/algorithms are being utilized by many large carriers.   

That said, the carriers that matter, Verizon, AT&T, T-Mobile & Comcast to name a few, are heavily invested in and utilize both SHAKEN and Call Labeling & Blocking software/algorithms to determine which calls are delivered and which calls are labeled or blocked. 

Here are some facts:

  • If your carrier is not SHAKEN and tokenizing 100% of your calls with an “A” Attestation, run, don’t walk, to another carrier.
  • All algorithms give heavy weight to a SHAKEN call containing an “A” Attestation.
  • If your calls are properly SHAKEN, when you call a buddy’s Verizon or T-Mobile cell phone expect them to see the “Check Mark” or “Verified Caller” on their handsets.

If you don’t see the “Check Mark” or “Verified Caller”, then your carrier either is not SHAKEN, or they do not have their SHAKEN routes in place to the carriers that count! – they are playing catch up on your dime. RUN, don’t walk!

Why do SHAKEN and Algorithms play in the same sand box?

Now with the industry’s launch of SHAKEN, the algorithm’s expectation is to see more SHAKEN tokens in the network. The token options are “A”, “B” or “C”.  And whether the token is present or not present, and depending on if it is an “A”, “B” or “C” has special meaning to the algorithm.

As the percentage of SHAKEN calls increases on the telecom network, the algorithms are increasing the weight given to the token; particularly an “A” attestation when deciding whether to label a call as “Potential XXX”.  

A SHAKEN call with an “A” Attestation validates:

a) this is not a spoofed telephone number

b) the caller is a known entity

c) the call can be traced back to the originating party.  

A call with a “B” Attestation means you could be passing an unrecognized CID. Your carrier needs proof you are authorized to use it – like an LOA. Sorting it out is easy, but it is VERY important because a “B” means a potentially spoofed call!

Note that some intermediary carriers are now inserting “C” Attestation on calls that traverse their network that arrive without a token and therefore do not contain an Attestation.  A “C” Attestation is a death sentence, even worse than a call with no token, because it says definitively “we do not know the calling entity, nor do we know if this was a spoofed number.” No worry, the algorithm knows exactly what to do!
