To stop cold calls in Austria, residents can report nuisance calls to the Rundfunk und Telekom Regulierungs-GmbH (RTR), the national regulatory authority for broadcasting and telecommunications. Reporting helps the regulator identify illegal marketing patterns and take enforcement action against companies violating the Telecommunications Act (TKG), which generally prohibits unsolicited marketing calls to consumers without prior explicit consent.
Austria maintains strict regulations regarding “cold calling,” or unsolicited telemarketing. Under the Austrian Telecommunications Act, companies are forbidden from calling private individuals for marketing purposes unless the person has given their clear, documented consent. When these rules are ignored, the RTR serves as the primary body for filing complaints and monitoring compliance across the national network.
The process of stopping these calls involves a combination of official reporting, technical blocking, and legal awareness. While many users feel that reporting a single call is ineffective, the RTR uses aggregated data to launch investigations into systemic offenders. This data allows the regulator to issue fines or warnings to companies that operate “robocall” centers or engage in aggressive sales tactics.
Reporting Nuisance Calls to the RTR
The most effective way to trigger a regulatory response is by filing a formal complaint with the RTR. According to the regulator’s guidelines, reports should be as detailed as possible to ensure the agency can trace the origin of the call. A vague report is rarely actionable; however, a report with specific data points allows the RTR to cross-reference calls across thousands of users to identify a specific offending company.
When filing a report, the RTR requests the following specific details: the exact phone number that appeared on the caller ID, the date and precise time of the call, and the name of the company or product being marketed. If the caller refused to identify themselves or used a “spoofed” number (a fake number designed to look local), this should also be noted in the report.
The RTR maintains a dedicated reporting portal for “Spam-Anrufe” (spam calls). By submitting these details, consumers contribute to a database that the regulator uses to determine if a company is operating a large-scale illegal campaign. If the RTR finds a violation of the TKG, it has the authority to impose administrative penalties on the entity responsible for the calls.
Identifying Scams vs. Legal Telemarketing
It is critical to distinguish between an illegal marketing call and a criminal scam. While both are nuisances, they require different responses. A standard cold call usually attempts to sell a legitimate, albeit unwanted, service like energy contracts or insurance. These are handled by the RTR.
Criminal scams, such as “spoofing” calls that mimic bank officials or government agencies to steal credentials, fall under the jurisdiction of law enforcement. According to the Bundeskriminalamt (Federal Crime Office), victims of phone fraud should report the incident directly to the police rather than the telecommunications regulator. Police reports are necessary for opening criminal investigations and attempting to freeze stolen funds.
Common red flags of a scam call include requests for immediate payment via unconventional methods, demands for passwords or PINs, and a high sense of urgency. Legitimate companies, even those calling illegally, will not ask for your banking passwords over the phone.
Technical Methods to Block Cold Calls
Beyond official reporting, users can employ technical barriers to reduce the volume of unwanted calls. Most modern smartphones (iOS and Android) include built-in “Silence Unknown Callers” features. This setting diverts calls from numbers not in the user’s contact list directly to voicemail, preventing the phone from ringing during a cold call attempt.
Third-party applications that utilize community-based blacklists can also be effective. These apps compare incoming numbers against a global database of reported spam callers and warn the user before they answer. However, users should verify the privacy policy of these apps, as some may collect contact list data in exchange for the blocking service.
For those using landlines, the options are more limited, but many providers offer “call screening” services. Checking with the specific telecommunications provider (such as A1, Magenta, or Drei) can reveal if there are network-level filters available to block known spam ranges.
Legal Rights and the “Right to Object”
If a person answers a call and discovers it is a marketing attempt, they have the legal right to object. Under the General Data Protection Regulation (GDPR), which applies in Austria, individuals can demand that a company delete their personal data and cease all further contact. This is known as the “right to erasure” or the “right to object.”

To make this effective, the caller should explicitly state: “I do not consent to this call and I demand that you delete my phone number from your database immediately.” If the company continues to call after this request, the violation becomes more severe, providing the RTR with stronger grounds for enforcement actions.
It is important to note that simply saying “stop calling me” may not be as legally robust as specifically invoking the right to data erasure under GDPR. Documenting the date and time when this request was made provides a paper trail if the user decides to escalate the complaint to the Austrian Data Protection Authority (Datenschutzbehörde).
Summary of Action Steps
- For illegal marketing: File a report with the RTR including the number, time, and company name.
- For suspected fraud: Contact the local police or the Bundeskriminalamt immediately.
- For immediate relief: Enable “Silence Unknown Callers” in smartphone settings.
- For data privacy: Explicitly demand the deletion of your data under GDPR during the call.
The next step for consumers is to monitor the RTR’s official announcements regarding new spam trends and updated reporting forms. As “AI-generated” voice scams become more common, the regulator is expected to update its guidance on identifying synthetic voices.
