STIR/SHAKEN Compliance for Schools and Organizations
Make sure your outbound calls get trusted, not labeled as spam.
STIR/SHAKEN is how phone carriers verify that a call really comes from the number on caller ID. Ambit signs your outbound calls with its own certificate, so parents, patients, citizens and customers are more likely to see a trusted call and pick up.
FCC-licensed carrier. Own SPC token and certificate. Robocall Mitigation Database filing.
What STIR/SHAKEN is
STIR/SHAKEN is the federal caller ID authentication framework created to fight illegally spoofed robocalls. It lets the phone company receiving a call verify that the call comes from the number displayed on caller ID.
In plain terms, it digitally signs outbound calls so downstream carriers know whether to trust them. For schools and businesses, that matters because a call that is not properly authenticated is more likely to be flagged, blocked or labeled as spam, and never reaches the person you are trying to reach.
Why your organization should care
Your organization may already be affected if:
- Parents are not answering calls from your school.
- Patients are missing calls from your office.
- Citizens are ignoring calls from a municipal number.
- Customers see “Spam Likely” instead of your name.
The phone call is still one of the most important channels for schools, government offices, healthcare organizations and businesses. When your calls are mislabeled or blocked, it affects operations, customer service, emergency communication and public trust.
The three attestation levels
A: full attestation
The provider knows the customer and has verified they are authorized to use that caller ID. This is the highest level of trust.
B: partial attestation
The provider knows the customer but cannot fully verify authorization for that specific caller ID.
C: gateway attestation
The provider is passing the call along but cannot verify the customer or the number. This is the lowest level of trust.
When Ambit hosts your numbers and provides your SIP trunking, and we have verified you as the customer, your calls are eligible for A-level attestation, the strongest caller ID trust signal available.
STIR/SHAKEN is more than a switch you flip
For a carrier, compliance means real work:
- Filing in the FCC’s Robocall Mitigation Database.
- Maintaining customer verification procedures.
- Obtaining our own SPC token and certificate.
- Managing number authorization.
- Keeping compliance documentation current as the rules change.
Providers that fall out of compliance or are removed from the database risk having other carriers stop accepting their traffic. If your provider is one of them, your calls go down with it. Ambit has done the carrier-grade compliance work so your organization does not have to manage any of it.
Why number ownership and SIP trunking matter
When Ambit hosts your numbers and provides your SIP trunking, we control your voice path, number authorization, routing and support. That is a stronger foundation for compliant, trusted calling than a reseller sitting between you and the network.
Questions to ask your current provider
Is my provider properly handling STIR/SHAKEN and robocall mitigation filings?
Providers that fall out of compliance can be cut off by other carriers.
Who hosts and controls my phone numbers?
The carrier that controls your numbers controls how your calls are signed.
Can my provider verify I am authorized to use my outbound caller ID?
Verification is what earns A-level attestation.
What happens if my calls start showing as spam?
You want to know who investigates and how fast they answer.
If your provider cannot answer these clearly, that is worth knowing.

Frequently asked questions
Straight answers for IT directors and business owners.
What is STIR/SHAKEN?
A federal framework that digitally signs outbound calls so the receiving carrier can verify the number on caller ID is real.
Will STIR/SHAKEN stop my calls from showing as spam?
It makes your calls more trustworthy, and an unsigned or unverified call is far more likely to be flagged. It does not guarantee a label will never appear, because carriers and call-labeling apps also look at call patterns and reputation.
What is attestation?
The level of trust a carrier assigns to a signed call: A when the carrier has verified the customer and number, B when it knows the customer but cannot verify the number, and C when it only passes the call along.
Do we have to file anything ourselves?
No. The filing, certificate and customer verification are the carrier’s responsibility. What you control is choosing a carrier that handles them, and keeping your numbers and caller ID details accurate.
How do we get A-level attestation?
Ambit hosts your numbers, provides your SIP trunking and verifies you as the customer, which makes your calls eligible for it.
What happens if our carrier is removed from the Robocall Mitigation Database?
Other carriers can stop accepting its traffic, which means your calls can stop going through.
