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.
