Use Cases

Voice automation at scale

See how businesses use AI agents to automate customer calls, qualify leads, and conduct surveys without human agents.

Automated Lead Qualification Calls

A sales team needs to qualify hundreds of inbound leads but lacks capacity. They configure the AI Agent to create a Bolna voice agent with qualification questions. When leads submit forms, the agent triggers outbound calls via Bolna's Make Call API. Leads receive instant callbacks, answer qualification questions, and hot leads route to sales reps.

Appointment Reminder Campaigns

A healthcare provider wants to reduce no-shows with phone reminders. They instruct the AI Agent to create a batch call campaign for tomorrow's appointments. The agent schedules calls via Bolna's batch API with patient names and appointment times. Patients receive personalized reminder calls and can confirm or reschedule by voice.

Post-Purchase Feedback Collection

A product team needs NPS scores from recent customers. They tell the AI Agent to initiate survey calls to last week's purchasers. The agent triggers Bolna voice agents that ask satisfaction questions in Hindi, Tamil, and English based on customer preference. Survey responses aggregate automatically for analysis.

FAQs

Frequently Asked Questions

How does the AI agent create Bolna voice agents?

The agent calls Bolna's Create Agent API with configuration including LLM provider (OpenAI, DeepSeek, Llama), voice synthesizer (ElevenLabs, Azure, Deepgram), conversation prompt, and telephony settings. New voice agents are ready for calls within seconds.

What languages do Bolna voice agents support?

Bolna supports 10+ languages including English, Hindi, Tamil, Telugu, Bengali, Marathi, and Hinglish. The agent specifies language when creating voice agents. Accent adaptation covers 50+ regional variations for natural conversations.

What telephony providers does Bolna work with?

Bolna integrates with Twilio, Plivo, and Exotel for telephony infrastructure. Configure your provider credentials in Bolna settings. The agent triggers calls through your existing telephony without additional setup.

Does Tars store call recordings or transcripts?

No. Tars retrieves call data from Bolna's API in real-time. Recordings, transcripts, and conversation logs remain within Bolna's infrastructure. The agent fetches execution details on demand for reporting.

Can the agent handle thousands of concurrent calls?

Yes. Bolna powers 500K+ minutes monthly across customers. The agent creates batch campaigns with thousands of recipients, and Bolna scales voice agent instances automatically. Latency stays under 500ms regardless of volume.

How is this different from traditional IVR?

Traditional IVR follows rigid menu trees. Bolna voice agents powered by LLMs understand natural speech, handle interruptions, and have contextual conversations. The agent configures truly conversational voice experiences, not button-press menus.

What LLMs can power Bolna voice agents?

Bolna supports OpenAI GPT-4.1 family, DeepSeek, Llama, Cohere, and Mistral models. Specify your preferred LLM when the agent creates voice agents. Different models offer tradeoffs between cost, latency, and conversation quality.

Can the agent monitor call outcomes in real-time?

Yes. The agent retrieves execution status via Bolna's API including call state, duration, and live transcript. For batch campaigns, it tracks completion percentage and aggregates outcomes for reporting.
