Voice is the section of Jelou where you manage your organization’s phone calls: the agents that speak, the log of what happened on each call, outbound campaigns, and the webhooks that notify your systems. It sits in the side menu, under Voice.

The two pieces you need to configure

A voice operation needs two things, and they’re created separately:

A voice agent

Defines the prompt, the first message, the voice, the language, and the tools it can use during the call.

A phone number

Provisioned by activating an ElevenLabs channel, with SIP trunk or Twilio.
The last step is connecting them: in the channel configuration you choose which agent answers inbound calls on that number.
An agent can exist without an assigned number. That lets you design and tune it before provisioning telephony, or reuse the same agent across several numbers.
If your customers already message you on WhatsApp, there’s a third path: you can enable voice calls on your own WhatsApp number without provisioning a new one. See WhatsApp calling.

​
How a call unfolds

​
What you can configure on an agent

An agent’s editor has four tabs, each covering a different dimension:

Behavior

System prompt, first message, voice, language, model, and maximum duration.

Tools

Seven native telephony functions and your own HTTP tools.

Knowledge base

Documents and URLs the agent consults to answer.

Analysis

Evaluation criteria and structured data extracted from every conversation.

​
All of this from the terminal too

The full voice service is available in the Jelou CLI, which lets you automate campaigns, queries, and deployments in your own scripts or in CI.
