Sigma Voice helps financial institutions streamline customer communication with automated fraud alerts, payment reminders, IVR surveys, and service updates. Built for compliance and scale, our platform reduces manual workload, improves response rates, and ensures secure message delivery — whether you're a community bank or an enterprise lender.
In the banking industry, secure, real-time communication is critical for fraud prevention, regulatory compliance, and enhancing the customer experience. Whether you’re sending payment reminders, delivering fraud alerts, conducting post-call IVR surveys, or coordinating internal communications across branches, Sigma Voice provides reliable, compliant solutions. Our automated voice, SMS, IVR, and telecom auditing tools help banks improve customer engagement, streamline operations, and reduce communication costs — all while meeting the highest standards of data security and financial compliance.
Voice broadcasting enables banks and credit unions to automate outbound calls for alerts, reminders, and customer updates. With support for both pre-recorded audio and text-to-speech, financial institutions can deliver consistent, secure messages while improving customer engagement and reducing manual outreach.
Automatically notify customers of suspicious activity, transaction verification needs, or account lockouts.
Send reminders for loan payments, account reviews, or scheduled appointments with banking representatives.
Inform customers or employees of temporary branch closures, service disruptions, or policy updates.
Interactive Voice Response (IVR) systems help banks and credit unions automate inbound and outbound phone interactions, improving efficiency and customer satisfaction. From account inquiries and loan application routing to post-call surveys and fraud verification, IVR solutions reduce call center load, maintain security, and provide 24/7 service access.
Let customers check balances, hear recent transactions, or make payments without waiting for a live agent.
Direct calls to the appropriate department — such as loans, credit cards, fraud support, or account services.
Collect customer feedback on service quality, resolution satisfaction, or onboarding experience with automated IVR surveys.
SMS broadcasting enables banks and credit unions to deliver secure, time-sensitive text messages to customers and staff. From fraud alerts and payment reminders to policy updates and appointment confirmations, SMS ensures direct, high-engagement communication that builds trust and improves responsiveness.
Send automated reminders for upcoming loan payments, account reviews, or scheduled meetings with banking staff.
Instantly notify customers about suspicious transactions, verification needs, or account lockouts.
Inform customers of hours of operation, service changes, compliance notifications, or new product offerings.
Accurate customer contact information is essential in banking, where timely communication can prevent fraud, improve service delivery, and ensure regulatory compliance. Sigma Voice’s phone number validation tools help verify mobile, landline, and VoIP numbers before sending voice or SMS messages — improving deliverability and reducing risk.
Identify and validate wireless numbers to help meet TCPA and banking communication standards, while respecting opt-in preferences.
Clean outdated or invalid numbers and organize contact lists by account type, branch location, or communication preference.
Reduce undelivered messages, avoid wasted outreach, and focus resources on verified customer contacts for alerts and updates.
Banks and credit unions often operate across multiple branches, departments, and telecom vendors — leading to hidden costs, unused lines, and billing inefficiencies. Sigma Voice’s telecom auditing service uncovers waste, corrects overcharges, and helps optimize spending — all without switching carriers or disrupting service.
Review telecom invoices and service agreements across locations to identify overcharges, missed discounts, or outdated contracts.
Find inactive or duplicated lines in branches, ATMs, or call centers to streamline telecom infrastructure and cut unnecessary costs.
Lower communication expenses and redirect savings toward customer services, digital transformation, or security upgrades — without interrupting operations.
Sigma Voice delivers secure, compliant, and reliable communication solutions for banks, credit unions, and financial institutions. Whether you're sending fraud alerts, conducting IVR surveys, delivering payment reminders, or auditing telecom use — every interaction is protected by enterprise-grade safeguards aligned with banking and data protection standards.
All financial communication — including call data, SMS messages, and IVR interactions — is transmitted over encrypted connections to protect data in transit.
Calls and messages are routed through trusted providers using secure protocols to prevent spoofing, interception, or unauthorized access.
Access to sensitive data is protected with role-based permissions, user authentication, and activity logging — ensuring accountability and internal compliance.
Sigma Voice aligns with the NIST Cybersecurity Framework and ISO 27001-aligned practices to support industry-standard security protocols for financial communications.
Tools are provided to manage customer opt-ins, opt-outs, and messaging preferences in compliance with CCPA, PIPEDA, and our Anti-Spam Policy.
Sigma Voice continuously monitors platform activity to detect suspicious behavior, reduce fraud risk, and ensure secure communication delivery at scale.
With Sigma Voice, financial institutions can protect sensitive information, meet regulatory requirements, and deliver secure communications with confidence.
In banking, communication systems — including IVR, voice broadcasting, SMS messaging, phone number validation, and telecom auditing — must comply with financial regulations to protect customer data, ensure documented consent, and maintain auditability. Sigma Voice helps banks and credit unions meet these requirements while reducing operational risk and improving communication efficiency.
Non-essential outreach — such as payment reminders or marketing messages — typically requires documented opt-in consent in accordance with CCPA, PIPEDA, and our Anti-Spam Policy.
All automated messages must identify the financial institution and explain the purpose of the message — supporting compliance, trust, and customer transparency.
Communication with customers should take place between 8 AM and 9 PM local time to comply with best practices and avoid disrupting account holders outside reasonable hours. These contact windows reflect industry norms and guidance from consumer protection laws.
Time-sensitive alerts — such as fraud warnings or account access notifications — may qualify for consent exemptions but must still follow secure communication protocols.
All communication logs, recordings, and contact data must comply with CCPA, PIPEDA, PCI, and align with secure storage standards detailed in our Privacy Policy and Terms of Service.
By meeting these regulatory standards, financial institutions can automate communication confidently — with the assurance that customer privacy, consent, and compliance are fully supported.
Sigma Voice empowers banks and financial institutions with a secure, scalable communication platform designed to support critical interactions across branches, departments, and digital channels. From IVR systems and voice broadcasting to SMS messaging, phone number validation, and telecom auditing — every tool is built to improve efficiency, enhance customer engagement, and ensure regulatory compliance.
Whether you're sending fraud alerts in real time, automating payment reminders, conducting post-call IVR surveys, validating contact data, or uncovering telecom waste across locations — Sigma Voice helps streamline communication while protecting sensitive financial information.
