The Architecture of Outbound
Voice Vetting AI
Go deep into the core modules of the Fawin platform. Vetting, dialing, criteria extraction, and data sync engines in one unified system.
Low-Latency Speech & Dialing Systems
Fawin integrates with secure hosted cloud dialer channels via the OmniDimension API, initiating calls concurrently across candidate rosters. The synthesis model uses natural, low-latency audio blocks to permit real-time human interjections.
Natural bilingual English, Hindi, and Hinglish dialogue
Smart call-vibration simulation controls
Candidate Profile Vetting

Wait, are you a bot or an AI?
I'm an AI assistant from the HR team — let's keep going, we're almost done.
Strict Topic Recovery & Bot Disclosure
Outbound voice vetting calls require ironclad topic steering to avoid prompt jailbreaks or candidates taking the AI off track. Fawin utilizes three-phase semantic boundary protection, gently yet firmly bringing the conversation back to the job description criteria.
Factual bot disclosure (no AI identity lies)
Strict conversational boundary compliance
Resume Scanning & Evaluation Matrices
Fawin extracts critical variables like notice period, location preference, and expected compensation directly from candidates, comparing them against the target JD criteria. The system enforces strict cut-off scores to screen out clear mismatches automatically.
Automatic buy-out & notice duration vetting
Eligibility threshold cut-offs prevents call waistages
Rohan Das
Senior Frontend Engineer
Highly skilled React developer. Core logistics criteria (15 days notice, Indiranagar location, budget alignment) match the job specification perfectly.
Outbound REST Webhook Callbacks
Integrations in Fawin are engineered for high extensibility. When a candidate's voice screening completes, Fawin transmits the structured profile metrics, notice period, location preference, and the full transcript directly to your secure API endpoint.
Encrypted AES-256 REST payload blocks
SOC2-compliant Supabase integration
