A2P (Application-to-Person) calling allows businesses to automate outbound calls, delivering critical messages at scale. Whether it’s appointment confirmations, fraud alerts, or marketing campaigns, Sigma Voice ensures high-quality calls, compliance, and real-time analytics for seamless communication.
A2P (Application-to-Person) calling refers to automated voice calls made by businesses or organizations to customers, clients, or members. Unlike traditional Person-to-Person (P2P) calling, which involves direct, manual communication between individuals, A2P calling is powered by software applications, allowing businesses to reach large audiences efficiently.
For example, a healthcare provider may use A2P calling to send automated appointment reminders, while an e-commerce store might notify customers of shipping updates.
A2P Calling: Automated, high-volume calls initiated by a business to deliver notifications, alerts, or promotions.
P2P Calling: Manual, one-on-one calls typically used for personal or business conversations.
A2P calling is powered by intelligent automation, seamlessly integrating with business systems to streamline communication. Here’s how it functions:
Calls are initiated through CRM systems, appointment schedulers, or marketing platforms based on predefined rules or customer actions.
Instead of requiring manual dialing, the system delivers thousands of calls simultaneously, ensuring timely communication.
Businesses can track call success rates, measure engagement, and refine their messaging strategy using detailed call insights.
