It takes the friction out of making calls to negotiate bills, book appointments, or check business hours. Instead of sitting on hold or repeating your information to a representative, you can just give your agent a prompt. It handles the conversation, manages the dialogue, and then provides you with a summary and a transcript of the whole thing. You can find Vibrato in the Vinkius catalog to get started quickly. It's built for anyone who needs to get things done over the phone without actually picking up the handset. Whether it's a complex negotiation or a simple booking, your agent can handle the heavy lifting while you stay focused on other tasks. You don't have to worry about the awkwardness of a live conversation or the time wasted waiting for a human to pick up. Your agent works through the script, asks the right questions, and gets the information you need. This changes how you handle outbound communications. You can call multiple utility companies to see if they can lower your rates without spending your afternoon on hold. It turns a tedious chore into a background task that happens while you do other work. You get the results without the headache of the actual call. ## Tools ### create_call This tool creates an AI-powered phone call by taking a prompt, phone number, and locale. ### get_call_status This tool checks the current status of a call to see if it is active, completed, or failed. ### list_calls This tool lists every AI call your agent has made, including all relevant metadata. ### list_templates This tool lists all available call templates so you can see what tasks your agent can handle. ### create_call_from_template This tool initiates a call using a pre-defined template for common tasks like bill negotiation. ## Prompt Examples **Prompt:** ``` Call +123456789 to negotiate my internet bill using the 'Telecom Negotiation' template. ``` **Response:** ``` I've initiated the AI call to negotiate your bill.
