## Build

**Agents.** Real first-name persona, spoken [system prompt](/guides/prompting), greeting, STT / LLM / TTS, tools, knowledge bases, caller memory, dynamic greeting, variables, post-call fields, versions, web tester.

**Knowledge base.** Upload files, search (`top_k`). Attach with `config.knowledge_base_ids`.

**Voice library.** Catalog voices by sanitized name (`priya`). Clone from a sample (JWT).

**Integrations.** Org-level webhook, MCP, and Composio tools.

## Deploy

**Phone numbers.** US: buy immediately. India: [KYC](/guides/kyc) must be **accepted** first. BYOK Twilio / Plivo / Exotel.

**UCC.** Plivo India voice. [UCC complaints](/guides/ucc) — submit opt-in proof within 5 business days. Do not call the complainant again.

**Inbound.** One telephony account → one agent + availability window.

**Outbound campaigns.** Batch + contacts or recipient list. Start / pause / resume / cancel / schedule.

**Deploy with code.** [Python SDK](/sdk/python) (`pip install kupe`), [TypeScript SDK](/sdk/typescript) (`npm install kupe-sdk`), [Kupe MCP](/kupe-mcp), [Realtime](/realtime).

## Monitor

**Analytics.** Total calls, connected, connect rate, volume by hour.

**Databases.** After each attached agent's call, a row is written (who called, started, duration, extracted fields). Export CSV / JSON. See [Databases](/guides/databases).

**Usage / billing.** Wallet, invoices. Cost-summary + daily. No checkout in the public API.

## Speech stack

STT **k-STT**, TTS **k-TTS**, LLM **Kupe**. Realtime model `kupe-realtime`. Do not name upstream vendors in product copy.
