Introduction to 008

Welcome to the 008 Agent documentation, your framework for building voice-only, multilingual AI agents with multiple synthetic voices. In this “Getting Started” section, we’ll cover:

1. What is a voice-first AI Agent?
2. What are Tools? (built-in vs. third-party)
3. What are Deployments?

Note

008 Agent is prompt-first: instead of designing call flows visually, you craft prompts that drive agent behavior in real time.

What is a voice-first AI Agent?

A voice-only AI Agent in 008 Agent is a prompt-driven conversational entity that:

• Speaks and listens via audio channels (no text UI).
• Supports multiple languages out of the box.
• Offers a variety of voices (male, female, accents, neutral, etc.).
• Operates prompt-first, meaning all logic and dialog are defined through dynamic prompts rather than flowcharts or state machines.

Key Characteristics

• Prompt-First: Behavior is entirely controlled by the LLM prompts you provide.
• Multilingual: Specify the language in your prompt (e.g., "Answer in Spanish").
• Voice Selection: Choose from platform-provided voice models or custom recordings.

What are Tools?

Tools are functions or APIs the agent can invoke during a call. There are two categories:

1. Built-in 008 Agent Telephony Tools

These are native to 008 Agent for managing calls (only for SIP deployments):

• hangUp: End the current call.
• call_transfer: Transfer the call to another number or agent.
• call_hold: Puts the call on hold. Can only be used if it is explicitly required by other tools.
• call_unhold: Unholds a held call.
• call_info: Use it to get all the call info. Useful to get current time and caller number, expect CDR data.

Tip

Each tool surfaces as a function your prompt can trigger. Proper JSON specification in your prompt ensures correct invocation.

2. Third-Party Tools

Clients can integrate their own APIs or services as external tools:

• CRM Lookups: Query customer data by ID.
• Ticketing Systems: Create or update support tickets.
• Database Queries: Retrieve or store call metadata.
• Custom Webhooks: Trigger operations in your backend.

Define each third-party tool with a name, input/output schema, and endpoint URL, so the agent knows how to call it.

What are Deployments?

Deployments are the endpoints through which your voice agent connects:

• Web (Web Voicebot): Embed a voice interface into web pages or applications, allowing live browser-based calls.
• SIP: Connect agents as VoIP extensions using SIP, handling inbound and outbound telephone calls.

These deployments determine the audio transport layer:

• Web Voicebot: Users speak via the browser’s microphone.
• SIP: Agents join PSTN or VoIP networks as phone extensions.
