The Phone Hub is the space dedicated to Lily, the AI agent specialized in phone calls. It brings together the setup of your voice agents, the launch of outbound call campaigns, and the tracking of your phone conversations. It's also the only Hub billed pay-as-you-go, from your credit balance rather than your subscription quotas.

To open it, click Phone in the sidebar; the first time, Lily's onboarding (3 questions, 2 to 3 minutes) opens before the Hub. As in the Acquisition Hub, several voice agents can coexist: a selector in the top left lets you switch between them and shows, under the name, the assigned phone number or No number.

A getting-started checklist lists the remaining steps: create your first agent, add knowledge, set up a phone number, make your first call, and launch your first campaign. To go faster, ready-to-use templates let you create an agent preconfigured for a use case: appointment scheduling, customer support, outbound lead generation, or reservations.

The Customization section has three tabs that define the agent's behavior.

The Communication tab lets you set the agent's name, photo, and voice, chosen from a library of voices you can listen to before selecting one. The system prompt, which contains its instructions, can be written by hand, through a guided form, or generated with AI.

The Skills tab lists eight actions you can enable during a call: send an SMS, extract the caller's key information, transfer the call to a configured number, book an appointment on a connected calendar (Calendly, Google Calendar), save a contact record in the CRM (HubSpot, Salesforce, Pipedrive), recognize the caller by finding their record, end the call politely, or detect voicemail.

The Knowledge tab feeds the agent with files, a URL, or text you type directly, as well as with your product sheets from the AI Brain.

The Campaigns section lets you call a list of numbers with the agent of your choice. Each campaign is set up with a free-text goal, a campaign-specific greeting message, a ring timeout, a limit on simultaneous calls, and immediate or scheduled launch.

The contact list is imported from a CSV, XLSX, or PDF file, with automatic detection of the phone number column.

The Conversations section brings together the history of your calls, and Numbers lists the numbers linked to your agents. Activity summary provides a daily report on call volume and results.

The Widget lets you add a call button to your website with a code snippet to paste just before the closing body tag. It can start collapsed or expanded, and offer a satisfaction rating at the end of the conversation.

Before putting an agent into production, Voice Test lets you try it by call or text message, free of charge and with no limit on the number of tries.
