Agent

guava.Agent is the entrypoint for creating Guava voice agents. Create an Agent instance, attach handlers, then attach to a channel.

Example

import os
import guava

# Define our agent
agent = guava.Agent(
    name="Nova",
    organization="Acme Corp",
    purpose="Help customers with their orders.",
)

# Register handlers
@agent.on_call_start
def on_call_start(call: guava.Call):
    ...

# Attach to a channel
agent.listen_phone(os.environ["GUAVA_AGENT_NUMBER"])

Constructor

Use the constructor parameters to configure your Agent's persona and goal.

guava.Agent(
    # The name the agent uses to identify itself to callers.
    name: str | None = None,

# The organization the agent represents.
    organization: str | None = None,

# High-level description of the agent's role.
    purpose: str | None = None,
)

Handlers

Register handlers to control and react to the call in real-time.

Handler Description
on_call_received This handler is invoked on incoming calls. You can chose whether to reject or accept the call. The default behavior if not provided is to accept every call.
on_call_start Called when a call begins. Unlike on_call_received, this handler is invoked for both incoming and outgoing calls. Use this handler to set initial tasks and context for the Agent.
on_caller_speech Called each time the caller speaks.
on_agent_speech Called each time the agent speaks.
on_question Called when the caller asks the agent a question it cannot answer from context alone. The provided answer is relayed back to the caller.
on_task_complete Called when the Agent completes a Task previously set using call.set_task.
on_search_query Provide dynamic search results for a searchable Field.
on_action_request / on_action Called when the caller asks for a specific action, e.g. "can I reset my password?"
on_session_end Called when the session ends. Read event.termination_reason to find out why the call ended.
on_reach_person Called when a reach_person task completes.
on_outbound_failed Called when an outbound call fails to dial.
on_escalate Called when an escalation is triggered.

Entrypoints / Channels

Attach the agent to a channel to start receiving calls.

Entrypoint Description
listen_phone("+1...") Listen for inbound phone calls on the given phone number.
`listen_webrtc("grtc-..." None)`
listen_sip("guavasip-...") Listen for inbound SIP connections to the given SIP code.
call_phone(from_number, to_number, variables?) Place a single outbound phone call.
call_local() Call the agent using your local audio device (for testing).
attach_campaign(campaign) Attach an agent to an outbound Campaign.
chat(variables?) Start an interactive terminal chat session with the agent (for testing).
test(variables?) Starts a live test session for programmatic testing.
test_roleplay(roleplay_prompt, variables?) Run an automated test where an LLM roleplays as the caller.

To attach an agent to multiple channels, or run multiple agents in the same process, use guava.Runner.
