Vanie AI vs Vapi: which AI voice platform fits?
Vapi is a strong voice-agent platform that defaults to Twilio in the United States. Vanie AI is built India-first: direct SIP integrations with Jio, Vi, Airtel, Tata, and Servetel, dual Exotel + Twilio support, TRAI/DPDP compliance baked into the call gate, INR billing via Razorpay, and a Gemini Live bridge tuned for Indian carrier latency.

| Exotel native support | First-class | Not first-class |
| Twilio support | Fully supported | Primary path |
| INR billing / Razorpay | Native | USD only |
| TRAI / DPDP compliance gate | Time window, NCPR DND, preamble, retention | No India-specific compliance layer |
| Real-time agent runtime | Gemini Live bridge | OpenAI / Anthropic / Deepgram providers |
| Voice pipeline | Gemini Live speech-to-speech (multilingual, India-tuned) | Deepgram / Whisper / others |
| Languages | 8 Indian languages + English, mid-call code-switching | ElevenLabs / Cartesia / others |

Where Vanie AI is stronger
- Direct SIP integrations with the five Indian carriers that matter (Jio, Vi, Airtel, Tata, Servetel) — no manual trunk setup. Vapi works if you bring your own SIP, but it is not its happy path.
- TRAI/DPDP compliance is enforced before the call connects: time-window gate, NCPR DND scrub, T&C acceptance audit, recording preamble, per-tenant retention windows. Vapi has none of this because it targets US regulation.
- Dual Exotel + Twilio routing in the same workspace — pick the cheaper carrier per region, fall over automatically. Vapi-on-Twilio is fine, Vapi-on-Exotel is not a managed path.
- INR billing through Razorpay; Vapi is USD-only, which adds FX overhead and pushes Indian customers onto credit cards.
- Native Google Calendar, Outlook / Microsoft 365, and Cal.com booking — the agent checks live availability and books mid-call. On Vapi you assemble booking yourself from tools and functions.
- Bring-your-own-Gemini-key billing: a flat monthly platform access fee instead of per-minute platform credits lowers the effective per-minute cost at volume, with BYO SIP / Twilio / Exotel on top.
Where Vapi is stronger
- Vapi has a deeper menu of pluggable model providers (OpenAI, Anthropic, Cartesia, ElevenLabs, Deepgram, etc.) — useful if you must use a specific LLM or TTS vendor. Vanie AI standardises on Gemini Live for the realtime path.
- Vapi has been in market longer and has more US case studies; pick it if your customer base is US/Western Europe and Indian carriers are not on the roadmap.

FAQ
- Why does Indian carrier support matter?
- Twilio outbound calls to Indian numbers route through international gateways, which adds carrier latency on top of model latency and can be flagged as telemarketing by Indian providers. Vanie AI uses domestic SIP into Jio, Vi, Airtel, Tata, and Servetel, so calls originate in-country with lower latency and higher answer rates.
- Can Vapi handle TRAI compliance?
- Not natively. TRAI rules — the 10 a.m. to 9 p.m. window, NCPR DND scrubbing, mandatory recording preamble, and explicit T&C acceptance — must be enforced by your application layer if you use Vapi. Vanie AI runs them as a pre-call gate so non-compliant attempts never reach the carrier.
- How does DPDP retention work on Vanie AI?
- Each workspace sets its own retention window for transcripts and recordings. Past the window, Vanie AI purges the audio in Cloudinary and the transcript in Postgres. A right-to-erasure endpoint lets you delete a specific caller on request, with an audit log of who triggered it.
- Is Vanie AI cheaper than Vapi for Indian outbound?
- Usually, yes. Vanie AI bundles STT/TTS/LLM into a flat rate: 5.5 credits/min base (5 call + 0.5 recording), or 7.5 with optional post-call extraction (~₹7.5/min ≈ $0.09). Vapi separates them, so a comparable build adds Deepgram (~$0.0043/min), a TTS provider (~$0.10/min), an LLM tier, and the Vapi platform fee, before Twilio India termination.
- Which calendars can the AI voice agent book into?
- Natively into Google Calendar, Outlook / Microsoft 365, and Cal.com — the agent checks live availability and confirms the booking during the call. On Vapi you assemble calendar booking yourself from tools and functions.
- Can I bring my own Gemini key, number, or carrier?
- Yes. On the BYO plan you connect your own Gemini API key and pay a flat monthly platform access fee instead of per-minute platform credits, which lowers the effective per-minute cost at volume. You can also bring your own SIP trunk, Twilio, or Exotel account.
- Can I bring my own LLM, STT, or TTS on Vanie AI?
- Vanie AI standardises on Gemini Live for the realtime path because it lets us guarantee the latency budget; per the project rules we do not bridge in Whisper or other STT providers. If multi-provider flexibility is your top criterion, Vapi is the right call.
- Do you have a Hindi voice that sounds native?
- Yes — and Tamil, Telugu, Marathi, Bengali, Gujarati, Kannada, Malayalam. Voices are tuned for the phonetics of each language rather than a generic Hindi-English accent.
- Is there a free trial?
- Yes — 500 credits on signup, no card. Roughly 65 minutes of voice agent time.
