Voice AI Capabilities & Telephony Features

Instant Human Interruption (VAD)

Silero Voice Activity Detection pauses AI speech mid-sentence the millisecond the caller starts speaking, eliminating unnatural speech collisions.

Native Indic Code-Switching

Powered by Sarvam Saaras & Bulbul models, callers can switch seamlessly between English, Hindi, and Punjabi mid-sentence without losing context.

Live Human Call Transfer

When a complex inquiry or high-value deal occurs, the bot executes a SIP REFER payload, transferring the live PSTN call to your agent team in <2 seconds.

Real-Time CRM & API Actions

During the phone call, the voice bot executes backend function calls to check database inventory, book calendar slots, or query customer account balances.

Supported Telephony & Cloud PBX Networks

Frequently Asked Questions

Are Voice AI callers compliant with TRAI DLT regulations in India?

Yes. Our SIP integrations enforce strict TRAI DLT registered headers, DND registry scrubbing, and explicit opt-out prompts on outbound campaigns.

What is the cost structure for running sub-300ms voice AI calls?

Because we deploy open-weights models and direct SIP trunks without third-party SaaS middleman markups, per-minute voice execution costs are reduced by up to 70%.
