Bolti Pricing Explained: A Transparent Cost Breakdown

Bolti, a voice AI platform for phone agents, offers transparent pay-as-you-go pricing starting at ₹7/min with a 50-minute free trial to help you build production-ready conversational agents. If you are evaluating voice AI costs before launching a campaign, this breakdown explains exactly what you pay for, how provider costs work, and how to estimate your monthly budget.

What does Bolti pricing actually cost?

Bolti pricing costs ₹7 per minute on a pay-as-you-go basis with no monthly seat fees, platform subscriptions, or upfront commitments. You only pay for the exact minutes your conversational agents spend on active phone calls.

Here is how this pay-as-you-go platform fee scales based on your monthly call volume:

• 1,000 minutes/month → ₹7,000
• 10,000 minutes/month → ₹70,000
• 1 lakh (100,000) minutes/month → ₹7,00,000

For example, a customer support team in Mumbai running outbound lead qualification calls for 8 hours a day with 5 concurrent agents will accumulate roughly 12,000 minutes per month. This translates to a base platform cost of ₹84,000—significantly lower than hiring, training, and managing five full-time telecallers in a metro city.

Before committing a single rupee, you can start a free trial to get 50 free minutes. This trial runs on the live telephony network, letting you test real outbound sequences or inbound helpdesks instead of restricted sandbox environments.

What is included in the ₹7/min platform rate?

The ₹7/min rate covers Bolti's core orchestration runtime, which connects speech-to-text (STT), large language models (LLMs), text-to-speech (TTS), and telephony into a single low-latency agent.

When your agent is on a live call, the platform runtime handles several critical tasks in real time:

• Sub-second turn-taking: Keeps response latency under 800ms so conversations feel natural and human-like.
• Telephony-grade noise cancellation: Filters out background traffic, office chatter, or static.
• Real interruption handling: Instantly stops the agent's text-to-speech stream the moment the caller speaks.
• Data storage and logging: Saves call recordings, generates transcripts with speaker labels, and stores metadata.
• Local data residency: By default, all managed cloud services run on E2E Networks infrastructure based in India, ensuring your data stays local.

What are the additional provider costs?

Additional provider costs cover the external services that power your agent's senses and brain: speech-to-text (STT), large language models (LLMs), text-to-speech (TTS), and telephony carriers.

Bolti does not lock you into a single vendor. In the Agent Setup Wizard, you can mix and match providers for each agent:

• STT (Speech-to-Text): Converts caller audio to text. Options include Deepgram (default for English), AssemblyAI, Cartesia, ElevenLabs, Azure, and Fennec (optimized for Indian languages like Hindi, Tamil, and Telugu).
• LLM (Large Language Model): Processes the text and decides the response. Supported models include OpenAI (GPT-4o and GPT-4o-mini), Google Gemini (2 Flash and Pro), and Groq (Llama-family models).
• TTS (Text-to-Speech): Synthesizes the agent's voice. You can select voices from ElevenLabs, Azure, and other providers directly in the agent's Speech tab.
• Telephony: Carries the call over the phone network. You can bring your own carrier (BYOC) using SIP trunks from Twilio, Plivo, or Exotel, or use Bolti-provided numbers.

Your all-in cost will be the ₹7/min platform fee plus these provider costs. For a typical English outbound call using Deepgram STT, GPT-4o-mini, and a standard TTS voice, the total cost ranges between ₹12 and ₹18 per minute. If you run multilingual campaigns using Fennec STT, the rates will adjust based on actual character and token usage.

How does data residency affect your total cost?

Data residency costs are fully covered under the standard ₹7/min platform fee for managed cloud deployments, keeping your application data, call transcripts, and audio recordings stored securely within India.

Bolti's managed cloud runs on E2E Networks infrastructure in India. This means:

• Application data and transcripts are stored in AWS RDS PostgreSQL databases located in the ap-south (India) region.
• Call recordings are saved in secure, S3-compatible E2E Object Storage in India.
• In-flight call audio is processed in memory on Indian servers and is never persisted.

If your compliance team requires that no data ever leaves the country, you can configure your agents to use India-resident STT and TTS providers (like Fennec or Azure India regions) to avoid international data transit.

When does on-premise deployment make financial sense?

On-premise deployment makes financial sense for enterprise organizations running high call volumes (typically over 5 lakh minutes per month) or those with strict regulatory requirements that mandate complete data isolation.

Bolti is built to be fully self-hostable. We package the entire stack—the API backend, agent runtime, SIP gateway, and observability layer—into standard Docker containers. An on-premise setup requires you to provision three node groups:

• App Node: Runs the backend API and agent workers (suggested size: 4 vCPU / 8 GB RAM).
• Realtime Node: Handles live audio mixing and SIP routing (suggested size: 8 vCPU / 16 GB RAM).
• Observability Node: Aggregates logs and metrics (suggested size: 2 vCPU / 4 GB RAM).

While the managed cloud is faster and more cost-effective for most SMBs, enterprise contracts allow you to run Bolti on your own private infrastructure (like AWS, Azure, or local Indian data centers) with custom commercial terms.

How does Bolti pricing compare to Bolna AI and Ringg AI?

Bolti pricing offers a transparent ₹7/min pay-as-you-go platform fee, whereas competitors like Bolna AI and Ringg AI often require monthly subscriptions or bundled plans that obscure the actual cost of underlying providers.

Frequently Asked Questions

Is there a monthly subscription fee for Bolti?

No. Bolti operates on a pure pay-as-you-go model at ₹7/minute for the platform runtime. You only pay for the minutes your agents are actively on calls, with no monthly seat fees or upfront commitments.

What are the additional provider costs?

In addition to Bolti's ₹7/min platform fee, you pay for the speech-to-text (STT), large language model (LLM), text-to-speech (TTS), and telephony providers you choose. For a standard English setup, this typically brings the all-in cost to ₹12–18/minute.

Can I bring my own phone numbers and carriers?

Yes. Bolti supports Bring Your Own Carrier (BYOC). You can connect your existing SIP trunks from providers like Twilio, Plivo, or Exotel directly inside the dashboard to maintain your negotiated carrier rates.

Where is my call data and recording stored?

By default, Bolti's managed cloud stores all application data, call transcripts, and audio recordings within India on E2E Networks and AWS RDS infrastructure. For strict compliance, you can also opt for an on-premise deployment.
