What is Vobiz and who is it built for?

Vobiz is an AI-native telephony infrastructure platform for developers and businesses building voice AI applications. It provides the full carrier-grade telecom layer — numbers, SIP trunking, voice APIs, WebRTC, and real-time AI media processing — in a single stack, purpose-built for the latency and compliance requirements of production AI voice agents.

How does Vobiz's 80ms latency actually work?

The 80ms figure is the end-to-end telephony latency — the time the call spends inside the telecom layer before your AI agent even begins processing. Vobiz achieves this through AI-native packet optimization, noise cancellation, and voice isolation built directly into the media stack. The result is a telephony layer that is effectively invisible, so your LLM and TTS can run at full speed.

What does the Vobiz Partner Program offer?

The Partner Program is for AI voice builders and systems integrators who want to power their product on Vobiz infrastructure without owning telecom operations. You provision customer accounts, control billing, manage DID inventory, and access call records and financial reconciliation through a single API — under your own brand and pricing. Vobiz runs under the hood. You own the customer relationship.

Is Vobiz ready for regulated markets?

Yes, by design. Encrypted media streams, PII redaction, consent signaling, and audit logs are built into the infrastructure and available on every deployment — across healthcare, BFSI, insurance, government, retail, and any other sector operating under regulatory scrutiny. You don't need to add compliance after the fact. It ships with the platform.

Does Vobiz lock me into its number infrastructure?

No. Your DID is invoiced in your name and is fully portable. It moves with you across vendors, AI partners, and stacks — with no carrier negotiations required to reclaim it. Vobiz maintains consistent outbound caller identity across all your campaigns globally, which also means fewer spam flags and better answer rates as your volume scales.

Can Vobiz handle enterprise-scale call volumes reliably?

Vobiz processes 5 million+ calls per day at 99.99% call initialization rate and 99.99% platform uptime. The architecture scales from 10 calls to 10,000 without configuration changes, with redundancy and failover designed specifically for real-time AI workloads — not traditional telephony patterns.

Is Vobiz an alternative to Plivo?

Yes. If you’re evaluating Plivo for SIP trunking or voice APIs in India, Vobiz covers the same ground on one account: SIP trunking, DIDs, voice APIs, and WhatsApp Business messaging, with TRAI/DLT-compliant call routing and automated eKYC number verification built in from day one. Sub-80ms latency and real-time audio streaming come standard, so AI voice agent teams aren’t stitching separate vendors together to get there.

Is Vobiz an alternative to Twilio?

Yes. Twilio is a global platform built for general-purpose telephony. Vobiz is built specifically for AI voice agents, with TRAI/DLT compliance handled natively for India rather than configured after the fact. SIP trunking, DIDs, voice APIs, and WhatsApp Business calling live on one account, with self-serve provisioning that includes automated eKYC, so compliance and number setup aren’t two separate projects.

Is Vobiz an alternative to Exotel?

Yes, though the two are built for different jobs. Exotel is built around traditional cloud telephony and IVR. Vobiz is built around AI voice agents: real-time audio streaming voice APIs, sub-80ms latency, and direct integration with the AI calling platforms teams are already building on, on the same DID and SIP trunking coverage, so the switch doesn’t mean giving up trunking you already depend on.
