Sigma Voice’s mass calling system empowers organizations to connect with thousands in moments. From emergency alerts to event reminders, our easy-to-use platform ensures fast, effective communication—helping you deliver your message exactly when it’s needed.
Mass calling is a modern mass messaging technology, similar to email and texting, but designed to broadcast a pre-recorded audio message to a list of contacts without manually dialing each phone number. The Sigma Voice platform simplifies this process, allowing you to launch call blast campaigns quickly from a computer, tablet, or smartphone.
With Sigma Voice, your audio message is delivered within minutes to all your contacts. Recipients who answer hear your message immediately. For unanswered calls, the system ensures your message is played on the contact's voicemail or answering machine after the beep.
When time is of the essence, traditional communication methods like regular mail or email often fall short. Snail mail is costly and slow, while email, despite being faster, typically achieves open rates of only about 25% according to MailChimp. Sigma Voice's web-based mass calling system delivers pre-recorded messages to your contacts within minutes—without requiring software licenses or managing phone lines. Detailed real-time reports ensure transparency, showing which calls were answered by humans or machines.
Deliver urgent messages to thousands of recipients in minutes—ideal for emergencies, last-minute updates, or time-sensitive announcements.
Unlike email, which often goes unread, voice calls demand attention and result in higher response rates, ensuring your message gets heard.
Whether you need to reach hundreds or thousands, our system scales effortlessly, eliminating the need for manual dialing or additional infrastructure.
Track call performance with detailed reports showing which calls were answered live, sent to voicemail, or went unanswered.

When using a mass calling system, it's essential to ensure compliance with relevant laws and regulations to maintain ethical practices and avoid legal issues. Below are key compliance considerations for utilizing mass calling systems:
Ensure compliance with the Telephone Consumer Protection Act (TCPA) and Do Not Call (DNC) regulations. Automated calling systems must only contact individuals who have provided explicit consent, and all calls must avoid contacting numbers on the DNC list.
Obtain prior consent from recipients to receive automated calls and provide a clear and simple process for recipients to opt-out of future calls. This ensures that your outreach is transparent and respects recipient preferences.
Clearly identify your organization at the beginning of each call and ensure that your message is accurate, informative, and not misleading. This promotes transparency and builds trust with recipients.
Follow federal and state-specific regulations regarding acceptable calling hours. Generally, automated calls should be made between 8 AM and 9 PM in the recipient’s local time zone.
Protect recipient data by complying with data privacy laws such as GDPR and CCPA. Ensure that personal information is securely stored and handled in accordance with privacy regulations.
Some types of calls, such as emergency notifications or public safety alerts, may be exempt from certain regulations. Ensure you understand when these exemptions apply and comply with specific requirements.
By following these legal best practices, businesses can use mass calling systems effectively while staying compliant with applicable laws. For further details on compliance and our terms, visit the Sigma Voice Terms of Service or consult with a legal professional for guidance on regulations specific to your business or location.
