Architected for Heavy Enterprise Call Volumes

Indian enterprises handle millions of daily voice inquiries with heavy accent diversity, network packet jitter, and strict TRAI regulatory constraints. QIXS.AI re-engineers telephony from the silicon layer up.

01 / SUB-650MS LATENCY

Human-Speed Conversational Turn

Natural human dialogue requires turns between 500ms and 750ms. By streaming WebSocket audio tokens directly through our localized Mumbai inference engine, QIXS.AI delivers sub-650ms conversational turns that eliminate the dreaded awkward silence of legacy voice bots.

SPEECH ENGINE: SARVAM SAARAS + DEEPGRAM
02 / NATURAL CONVERSATIONAL BARGE-IN

Zero Awkward Audio Collisions

Callers don't wait for robots to finish long sentences. Our streaming Voice Activity Detection (VAD) instantly halts the synthetic voice playback within 40ms when the user speaks, absorbs the interruption context, and smoothly steers the conversation.

VAD LATENCY: 40MS SPEECH DETECTION
03 / CARRIER-GRADE SIP TRUNKING

Bring Your Own Carrier (BYOC)

Connect directly with Indian enterprise telecom carriers including Tata Teleservices, Bharti Airtel, Reliance Jio, Plivo, and Twilio. Maintain existing telecom rate contracts while scaling to thousands of concurrent SIP channels with zero degradation.

TRUNK CAPACITY: 10,000+ CONCURRENT SESSIONS
04 / TRAI 140 & 160 SERIES OUTBOUND

100% Indian Regulatory Compliance

Commercial outreach is strictly segmented: promotional telecalling over 140-series numbers and transactional/service calls over 160-series numbers with automated DLT header scrubbing and strict quiet hours (09:00 to 20:00 IST) fail-closed enforcement.

REGULATION: TRAI TCCCPR 2018 FRAMEWORK
05 / ZERO-DTMF SMART IVR

Replace "Press 1" with Fluid Dialogue

Eliminate 5-level deep DTMF phone trees that cause 40% caller drop-offs. Smart IVR lets callers speak freely in Hindi, English, or Hinglish ("Mujhe meri flight ka status check karna hai") and extracts PNR, dates, and intent with 98.4% accuracy.

INTENT ACCURACY: 98.4% INDIC NLU
06 / DOT IMMUTABLE CDR RETENTION

Sovereign 2-Year Telecom Compliance

Department of Telecommunications (DoT) mandates 24-month immutable storage for Call Detail Records (CDRs) and IPDR logs. QIXS.AI writes encrypted audit records directly to Write-Once-Read-Many (WORM) sovereign Indian cloud storage.

AI Voice Telephony & Smart IVR FAQs

QIXS.AI achieves sub-650ms p50 latency through continuous full-duplex WebSocket streaming, localized edge speech inference (Sarvam Saaras v3 for Indic languages and Deepgram Nova-2 for Indian English), chunked token-by-token LLM generation, and ultra-fast neural voice synthesis (Sarvam Bulbul and Cartesia) hosted in sovereign Mumbai data centers.
Barge-in allows human callers to interrupt the AI voice agent naturally at any point in the conversation. When the caller begins speaking, our streaming Voice Activity Detection (VAD) detects speech within 40ms, instantly cancels the active text-to-speech audio stream, clears the speaker buffer, and processes the caller's new intent without robotic overlap.
QIXS.AI integrates with tier-1 telecom carriers including Tata Teleservices, Airtel, Reliance Jio, Plivo, and Twilio via standard SIP (Session Initiation Protocol) trunks and WebRTC gateways, supporting thousands of concurrent channels with high availability.
Instead of forcing callers to listen to rigid 'Press 1 for Sales, Press 2 for Support' DTMF options, Smart IVR engages in natural conversation from the first second. It parses multi-intent Hindi, English, and Hinglish queries, extracts account numbers and entities, and intelligently routes or resolves the inquiry immediately.
Under the TRAI TCCCPR 2018 framework, all promotional outbound calls are routed strictly via registered 140 series numbers, while transactional, OTP, and service calls utilize 160 series numbers. QIXS.AI performs automated DLT template scrubbing and enforces strict calling hours between 09:00 and 20:00 IST.
