Solution

Our Solution

Divtechnosoft built Ringlyn's complete system: the web front end, the backend APIs, the voice AI integration and the infrastructure for scale. Each of the four challenges above needed a different answer.

Advanced AI Engine

OpenAI handles conversation and intent, ElevenLabs handles voice synthesis. Domain vocabulary injected per client, or a specific speech-to-text model chosen for accent range.

Telephony and Latency

Twilio handles inbound and outbound calling with real-time routing.

Analytics Dashboard

Comprehensive dashboard for monitoring call metrics, agent performance, and business insights.

Data Security and Compliance

For the GDPR and data handling challenge, we built on Supabase with role-based access control and encrypted data storage.

Key Features

Powerful features that enable businesses to automate their communication workflows.

Inbound & Outbound AI Voice Agents

Handle both incoming customer calls and proactive outbound campaigns with AI agents.

Call-Routing & Workflow Automation

Intelligent call routing based on intent, priority, and agent availability.

Lead Qualification & Appointment Booking

Automatically qualify leads, schedule appointments, and update CRM systems.

Role-Based Access Control

Granular permissions for admins, managers, and agents with activity tracking.

Real-Time Analytics

Live dashboards showing call metrics, conversion rates, and agent performance.

CRM & Calendar Integrations

API layer for seamless integration with popular CRM and scheduling systems.

Secure & Scalable

Enterprise-grade security with infrastructure that scales to handle high call volumes.

Questions About This Build

An AI voice agent answers and places phone calls on a business's behalf. It understands what the caller says, follows a defined workflow, and can qualify a lead, book an appointment or hand the call to a person when the conversation needs one.

The voice layer comes together quickly, because telephony and speech models are available as services. Most of the build time goes into call workflows, CRM integrations, and handling the cases where the agent should stop and pass the call to a person.

Yes. Ringlyn connects to CRM and calendar systems, so a qualified lead or a booked appointment lands in the tools the team already uses rather than in a separate dashboard nobody checks.

With explicit fallback paths. The agent recognises when it is out of its depth and routes to a human rather than guessing. Designing those paths is as much of the work as the happy path.
