Next-Generation Architecture

Five Technological Pillars of Kall AI

Engineered from the ground up for high-touch service businesses, doctors, and professionals who cannot afford to miss valuable leads.

Silent On-Device Call Screening Gate

Kall AI leverages Android's native RoleManager.ROLE_CALL_SCREENING to inspect incoming caller IDs locally in milliseconds. When auto-answer is enabled, the call is declined silently without your phone ever ringing.

Zero network latency on local decision
Respects weekly schedule windows

1-Tap Universal Carrier Forwarding

No memorizing arcane MMI codes. Kall AI provisions standard telecom conditional call forwarding (*67 / *61 / *62) for Airtel, Jio, Vi, and BSNL in one single tap with auto SIM slot selection.

Seamless dual-SIM support
Instant 1-tap deactivation anytime

Gemini Flash-Lite & Cloud Speech

Sub-second natural conversational flow. Callers speak freely in English, Hindi, or Hinglish; Kall AI transcribes with Google Cloud STT, generates context-aware replies via Gemini Flash-Lite, and speaks back in human tones.

Natural interruption handling
Function calling for catalog & slot booking

DPDPA 2023 Mandatory AI Disclosure

Every call begins with an unalterable verbal disclosure in the caller's language that they are speaking with an AI assistant. Every disclosure event is logged to immutable compliance audit records.

Answers to Common Questions

Frequently Asked Questions

Everything you need to know about setting up and running Kall AI on your Android phone.

How does 1-tap call forwarding work with my carrier?

When you tap "Activate Forwarding" inside Kall AI, the app automatically triggers standard carrier conditional diversion codes (e.g. *67 for busy, *61 for unanswered). When a call arrives that you reject or do not answer, your telecom carrier routes the audio stream to our dedicated cloud receptionist number. You can deactivate it at any time with one tap.

Why does Kall AI request the Call Screening role?

Kall AI uses Android's official RoleManager.ROLE_CALL_SCREENING to inspect incoming calls on-device. When auto-answer is turned ON (or during your configured schedule), the screening service rejects the call silently without vibrating or ringing your phone. The carrier detects the busy signal and instantly routes the caller to the AI assistant.

Is Kall AI compliant with the Digital Personal Data Protection Act (DPDPA 2023)?

Yes, strictly so. Every call starts with a mandatory verbatim AI disclosure greeting disclosing that the caller is speaking with an AI assistant in their language. Furthermore, each disclosure event is recorded in an immutable audit log, data is held under strict user-specific Firestore security rules, and all transcripts are subject to user-governed 30-day retention policies.

How are minutes billed?

Minutes are counted only while your AI assistant is actively speaking with an incoming caller. You can view your real-time balance on the dashboard. Subscriptions and minute recharge top-up packs are purchased safely through Google Play In-App Billing.

Does Kall AI make outbound marketing or cold calls?

No. Kall AI is strictly an inbound reception tool. It never initiates unsolicited calls or conducts telemarketing campaigns.
