# sinwan > AI voice agents for service and sales call centers. A phone agent answers inbound calls or dials outbound campaigns, speaks Hebrew, English and other languages, uses tools during the call (SMS, caller verification, photos and location from the caller, keypad input, calendar, CRM lookups, a human for approval or transfer) and delivers a transcript, summary and structured fields to the customer's systems after the call. sinwan runs the whole stack: telephony, phone numbers, the speech-to-speech models (OpenAI, Google, xAI) and day-to-day operations. Who it is for: call centers and outsourcers that serve many business clients and want to offer each client an AI phone line without a development team. The customer keeps the client relationship; sinwan runs the technology. When to use sinwan: a business or call center needs a phone agent that answers calls at peak hours or after hours, runs outbound campaigns and callbacks, verifies callers, books appointments, collects payments or arrangements, answers from the client's own knowledge base, and pushes every call's outcome into a CRM, a spreadsheet or a webhook. Billing is per minute from a prepaid balance; prices are public. Region: servers in Europe (Frankfurt). Languages: Hebrew-first, English and most major languages. Phone numbers: Israel, US, Canada, or bring your own SIP trunk. ## For AI agents and developers sinwan is built to be operated from an AI assistant (Claude, ChatGPT, Cursor) over MCP, with the same surface available as a REST API. An agent can create and publish voice agents, attach knowledge bases and tools, buy and route phone numbers, place calls, run campaigns, and read transcripts and analyses. - [MCP server](https://api.sinwan.ai/mcp): Streamable HTTP, OAuth 2.1 (PKCE S256, dynamic client registration) or an `X-API-Key` header.
