Call 48 Explains STIR SHAKEN Call Attestation

As a carrier that is STIR SHAKEN compliant, Call 48 certifies origination calls by attesting to the relationship with the caller, as well as their authority to use the DID phone number in question. The use of an attestation indicator represents the originating signer’s ability to vouch for the accuracy of the source of origin of the call.

Think of it like vouching for a friend when you them fix up. You know who they are, what they stand for, and their intentions. STIR SHAKEN attestation is like that. It’s a carrier’s way of saying we know who the provider is and vouch for them. Attestation comes in the form of either an A, B, or C.

Just because a caller receives an ‘A’ rating, it doesn’t necessarily correlate to their trustworthiness. Analytics will remain in place for call validation treatment to ensure that unwanted, scam, or illegal phone calls will still be labeled accordingly.

Let’s take a deeper look at what each rating means:

[A] Full Attestation
With Full Attestation, Call 48 has authenticated that the calling entity is authorized to use the number they’ve dialed from.

[B] Partial Attestation
Partial Attestation attests that Call 48 has authenticated the customer originating the call but cannot verify if the customer is supposed to be using the number dialed from.

[C] Gateway Attestation
With Gateway Attestation, Call 48 is able to authenticate a call’s origination but not its source. This type of call attestation is typically given to international calls.

Call 48 Explains STIR SHAKEN 101

Hate robo spam calls? The FCC has heard your complaints and STIR/SHAKEN is one of their largest steps to deal with the robo call situation. Put into place officially on June 30, 2021, service providers are now required to adopt STIR/SHAKEN solutions and Call 48 is compliant.

Between three and five BILLION robocalls are made each month, and research suggests that more than 40% of those calls are thought to be fraud-related. Call 48 is STIR/SHAKEN compliant, as this industry-wide initiative to restore trust in our voice communications is in effect. The goal of STIR/SHAKEN is to prevent fraudsters from scamming consumers and businesses through robocalls and illegal phone number spoofing, while making sure that legitimate calls reach the recipient.


STIR/SHAKEN is a technology framework designed to reduce fraudulent robocalls and illegal phone number spoofing. STIR/SHAKEN is a framework that assigns a certificate of authenticity to each phone call for use across the telecom network, acting as a digital signature of trust passed from carrier to carrier to improve traceable call delivery.

Surprise! STIR/SHAKEN is actually an acronym. STIR stands for Secure Telephony Identity Revisited. SHAKEN stands for Secure Handling of Asserted information using toKENs.

Ok, so STIR and SHAKEN are two different things. So what’s the difference?
STIR is a working group within the IETF, an internet standards body, which has developed a set of protocols used to create a digital signature for a call. The signed call includes information about the calling party and allows for verification of the signature by the terminating provider. SHAKEN are the standards for how STIR is to be deployed by service providers within their networks.

The Call 48 Guide to Measuring VoIP Scalability

If the pandemic taught us anything, it’s that in a moment’s notice a business might not only slow down, but it might hit a meteoric boom in need. Call 48 offers complete scalability and flexibility to our customers. But when we speak about scalability, we mean much more than adding phone lines and features.

Scalability and flexibility go hand in hand as they adjust to the demands of an active business. But they don’t mean the same thing. They differ in the sense that flexibility also refers to the way users configure and employ features. The ability to change components as needed contributes to a system’s efficiency overall. Even if adding lines is a simple process, the time it takes to setup and modify needs factoring too. This is where usability and scalability collide.

Of course, everyone wants to focus on growth. Scalability is perfect for adding new lines and features as your business demands grow. But did you know that scalability also pertains to when a system needs to downsize? Don’t look at VoIP service and solutions downsizing as a bad thing. In many ways, it’s not. Businesses also need to downsize for a variety of growth purposes. The modern workforce spends less time in the office, either working from home ortelecommuting on the road, so accessibility directly determines a system’s scalability.

Call 48 is able to measure the effects a system’s tools have on its efficiency. The importance of scalable communications includes benefits such as decreased transition time, cost reduction, market resilience and increased communications efficiency. In regards to accessibility, a scalable system must also be compatible
with a range of devices.
