A Twilio Dialer Calling & Messaging App
Talk to the Team
TapLocal sought to provide a robust white-label communication solution for B2B clients requiring seamless internal and external connectivity. The business faced pressure to deliver a reliable, multi-channel VoIP platform that could handle complex call management and data synchronization. Their goal was to launch a scalable, professional-grade application that would empower their clients to manage global communications efficiently while maintaining high standards of operational reliability.
We engineered a comprehensive cross-platform communication suite using Flutter and Laravel, integrated with Twilio to provide enterprise-grade VoIP capabilities. This solution serves as a white-label asset for B2B firms, enabling them to offer their own clients advanced calling, messaging, and contact management features. By centralizing WhatsApp, SMS, and voice services into a single, unified application, we enabled the client to provide a professional communication tool that simplifies complex workflows.
The client faced significant operational hurdles in synchronizing disparate data streams and maintaining call stability within their existing communication infrastructure.
Data Synchronization and API Integration
The client struggled to fetch and register user data from their API into a centralized database, which hindered their ability to manage specific numbers effectively and slowed down service deployment.
We implemented a robust verification system that authenticates API credentials and ensures accurate data registration, allowing the client to manage specific number sets with complete reliability.
Active Call Management and Reliability
The client lacked the ability to restrict incoming calls during active sessions, leading to fragmented user experiences and unreliable call handling that disrupted professional workflows.
We engineered intelligent call restriction logic and automated merge call facilities, ensuring that users maintain uninterrupted communication sessions without the risk of unexpected call interference.
We engineered an intuitive Twilio-powered dialer that enables seamless cloud telephony. This feature allows the client to provide their users with reliable, location-independent calling capabilities at any time.
We built a comprehensive logging system that captures detailed call records and metadata. This enables the client to offer professional users a reliable way to audit and review past communications.
We integrated a bulk messaging engine that supports both SMS and MMS protocols. This allows the client to provide a scalable, global messaging facility directly through the mobile application interface.
We developed a unified interface that integrates WhatsApp via API. This enables the client to offer a centralized platform for managing multi-channel business conversations with streamlined approval and setup processes.
We created a structured contact management module that stores names, numbers, and profile images. This ensures the client provides a professional, organized database for all essential business communication details.
TapLocal is built with Flutter for cross-platform mobile development, Laravel for backend, Twilio for communication APIs, and Firebase for push notifications.
