How We Automate Customer Calls Using VoIP
Customer communication is at the heart of every business. At Cosarn Technologies Ltd, we built Vacocaller, a VoIP-based solution that automates outbound and inbound calls—saving time, reducing costs, and improving customer engagement.
📞 What Is Vacocaller?
Vacocaller is a VoIP platform that integrates with telecom infrastructure to automate voice communication using:
- SIP trunks
- WebRTC
- API-driven call workflows
⚙️ How It Works
1. Trigger Event
A system event (e.g., missed payment, appointment reminder) triggers a call.
2. Call Initiation
Vacocaller sends a request via SIP to a telecom gateway (e.g., Airtel or MTN).
3. Voice Playback / Interaction
- Pre-recorded messages
- Text-to-Speech (TTS)
- Interactive Voice Response (IVR)
4. Call Logging & Analytics
All call data is stored and analyzed for performance insights.
🧠 Behind the Scenes Tech
- PBX Systems (e.g., Asterisk or Vodia PBX)
- SIP Protocol for call signaling
- RTP for media streaming
- Backend APIs (Django/Flask)
🔁 Automation Use Cases
