Sigma Voice helps hospitals, clinics, and medical networks reduce no-shows, streamline operations, and engage patients with secure, automated communication. From appointment reminders and test result notifications to post-visit surveys and internal alerts, our platform ensures timely, compliant outreach without adding to your team’s workload.
In the healthcare industry, secure and timely communication is essential for improving patient outcomes, reducing no-shows, and keeping staff and stakeholders informed. Whether you’re sending appointment reminders, conducting post-visit IVR surveys, notifying patients about test results, or coordinating internal updates across departments, Sigma Voice provides reliable, HIPAA-compliant solutions. Our automated voice, SMS, IVR, and telecom auditing tools help healthcare providers increase efficiency, enhance patient engagement, and reduce operational costs — all while maintaining the highest standards of privacy and compliance.
Voice broadcasting allows healthcare organizations to automate calls for patient reminders, care coordination, and operational updates. With both pre-recorded audio and text-to-speech options, healthcare teams can deliver secure, consistent messages while reducing staff workload and improving patient engagement.
Reduce no-shows by automatically reminding patients of upcoming appointments, checkups, or procedures.
Notify patients about prescription refills, vaccine availability, wellness campaigns, or follow-up instructions.
Share real-time updates with staff about policy changes, emergency protocols, shift changes, or system outages.
Interactive Voice Response (IVR) systems empower healthcare organizations to streamline inbound and outbound communications. From appointment scheduling and prescription refills to patient surveys and call routing, IVR reduces staff burden, ensures HIPAA-compliant interactions, and improves the overall patient experience.
Allow patients to confirm, cancel, or reschedule appointments without speaking to a receptionist.
Route callers to billing, pharmacy, nurse lines, or specialty clinics with customizable call flows.
Use outbound IVR surveys to gather feedback on patient satisfaction, wait times, and quality of care.
SMS broadcasting allows hospitals, clinics, and healthcare organizations to deliver timely, HIPAA-compliant text messages to patients, staff, and caregivers. From appointment reminders to wellness tips and critical alerts, SMS ensures fast, direct communication with high engagement.
Reduce no-shows and improve attendance rates with automated text reminders for upcoming appointments or procedures.
Notify patients about health risks, medication recalls, flu clinics, or emergency protocols.
Share wellness programs, policy changes, office closures, or insurance updates in real-time.
Accurate patient contact information is essential in healthcare, where timely communication can impact health outcomes. Sigma Voice’s phone number validation tools help verify mobile, landline, and VoIP numbers before sending voice or SMS messages — ensuring reliable delivery and compliance with healthcare regulations.
Identify and validate wireless numbers to help meet communication regulations and patient opt-in preferences.
Eliminate invalid or outdated numbers and organize by department, service line, or appointment type to streamline outreach.
Minimize delivery failures and messaging costs by validating numbers before sending time-sensitive medical alerts or reminders.
Hospitals, clinics, and healthcare networks often juggle complex telecom setups across multiple locations and vendors — resulting in billing discrepancies, underutilized lines, and excessive costs. Sigma Voice’s telecom auditing service identifies waste, corrects overcharges, and improves efficiency — all without changing carriers.
Examine telecom invoices across departments and locations to uncover billing errors, expired discounts, or contract mismatches.
Identify inactive phone lines in exam rooms, offices, or legacy systems to eliminate unnecessary telecom spend.
Reduce telecom expenses and reallocate savings to clinical operations, staffing, or new technology — without any service disruption.
Sigma Voice provides HIPAA-compliant, secure, and scalable communication tools for hospitals, clinics, and healthcare networks. Whether you're delivering IVR surveys, appointment reminders, patient alerts, or telecom audits, every message is supported by healthcare-grade safeguards and enterprise-level security standards.
All communication — including voice calls, SMS messages, and IVR responses — is transmitted over encrypted connections to protect data in transit.
Messages are routed through trusted providers with safeguards to prevent spoofing, interception, or unauthorized access.
Platform access is restricted through role-based permissions, user authentication, and audit logging — ensuring only authorized personnel can access sensitive data.
Tools are built in to manage opt-ins, opt-outs, and communication preferences in line with privacy regulations and our anti-spam policy.
Activity is continuously monitored to detect anomalies, prevent misuse, and protect against unauthorized message delivery.
With Sigma Voice, healthcare providers can communicate confidently — knowing their outreach is built on secure infrastructure and responsible data practices.
In healthcare, communication systems — including IVR, voice broadcasting, SMS messaging, phone number validation, and telecom auditing — must comply with strict legal frameworks to protect patient privacy, document consent, and ensure responsible outreach. Sigma Voice helps providers meet these obligations while reducing no-shows, improving engagement, and supporting efficient operations.
All communications involving Protected Health Information (PHI) must follow the Health Insurance Portability and Accountability Act (HIPAA), ensuring sensitive data is handled securely and lawfully.
Non-emergency messaging — including appointment reminders and health alerts — generally requires documented consent, in compliance with CCPA, PHIPA, PIPEDA, and our anti-spam policy.
Every automated message must identify the sender and the purpose of the call or text to ensure transparency and compliance with outreach regulations.
Messages should be delivered between 8 AM and 9 PM local time, unless exempted under emergency or time-sensitive circumstances.
Certain communications — such as prescription notifications or appointment changes — may qualify for legal exemptions but still require responsible and secure delivery.
By aligning with these standards, healthcare organizations can automate outreach confidently — with full awareness of their legal responsibilities. For more details, see our Terms of Service and Privacy Policy, or consult your legal team.
