Major Callers: What Changes with Anatel's New Rules

The telecommunications market in Brazil has just received an important update. Decision Dispatch No. 787/2025, published by Anatel in October, establishes new rules for the control of mass calls. The standard is in force until October 31, 2028 and brings direct impacts to the routine of carriers and service providers.

The main focus is to combat fraud, robocalls and abusive calls. For those managing a telecom network, this means significant technical, legal and operational adaptations. It is not just a matter of compliance. It is a matter of business continuity and security.

Who are the Major Callers

The standard clearly defines who is the target of these requirements. Individuals or legal entities that originate more than 500,000 calls per month are considered "major callers." This limit is counted by provider and by type of service, whether mobile or fixed.

If you have a corporate client with this volume of traffic, they automatically fall into this category. As of now, these users are required to authenticate all calls they make. Authentication must follow the technical specifications defined by the Call Authentication Working Group, GT-Autentica.

Obligations of Carriers

The responsibility does not fall only on the person making the call. The dispatch gives an active role to telecom providers. You will be the supervisor of this process. Carriers need to monitor the volume of calls originated by each client.

It is necessary to identify who exceeds the limit of 500,000 calls. Upon finding a major caller who is not authenticating their calls, the provider must notify them immediately. You need to grant a 30-day deadline for the user to adapt to the standards.

If the client does not regularize the situation within this deadline, the carrier is obliged to block the ability to originate calls. The block can only be reversed when there is complete regularization of the user.

Reports and Supervision

Bureaucracy also increases. Carriers must send monthly reports to Anatel by the 15th day of each subsequent month. These documents need to contain detailed information about authenticated users, sent notifications, blocks performed and exemption requests.

These reports are the basis for the Agency's supervision. Keeping data organized and accessible is fundamental. Lack of information or sending incorrect data can expose the carrier to regulatory risks.

Flexibility and Exemptions

The standard provides exceptions. Situations such as public services, essential services or those that do not involve massive teleservices may have flexibility or total exemption from the authentication obligation. This includes medical emergencies, civil defense and public security.

However, this exemption is not automatic. The user must submit a joint request with the provider. This request must be filed in the Electronic Information System, SEI, of Anatel. It is a process that requires technical and legal alignment between you and your client.

Operational and Technical Impact

In practice, your network needs to be prepared. Implementing robust authentication and monitoring mechanisms is not trivial. You will need to adapt your internal systems, such as SoftSwitches and SBCs, to support these new requirements.

The integration of these technologies must be precise. It will be necessary to monitor and control major callers continuously. The goal is to identify and mitigate risks of abuse or fraud in real time. Those who do not have a flexible and scalable infrastructure will have difficulties meeting deadlines.

Legal and Contractual Adaptations

The challenge goes beyond engineering. There is a strong legal component. Carriers need to review contracts with other interconnection service providers and teleservices.

It is essential to include specific clauses that regulate authentication. Contracts must establish clear responsibilities. The conditions for notifications and blocks need to be well defined to avoid legal disputes.

Documentation and Compliance

Documentation is a critical point. The company must keep detailed records of everything. You need to prove compliance with the notifications issued and the blocks effected. This guarantees transparency and auditability for your operation.

This requirement reinforces your responsibility before the Agency and the consumer. Having a well documented process is your line of defense in case of inspection.

Sanctions and Risks

Non-compliance with these standards brings serious consequences. Dispatch No. 787/2025 provides for rigorous administrative sanctions. Penalties range from warnings to severe fines applied by Anatel.

The Agency's goal is to ensure a high standard of governance. Operating without compliance can compromise the financial health of the company and trust in the market.

Conclusion

The new rules raise the standard of control and security in call traffic. Although they require relevant adaptations, the trend is to increase the reliability of networks and reduce unwanted calls.

For the provider or carrier, the time is for action. Check who your major callers are. Evaluate the capacity of your SoftSwitch and SBC to support authentication. Review your contracts and prepare your team for constant monitoring. Technology and organization are your best allies to comply with this regulation and keep your operation safe.
