Overview
The Phone agent mode allows you to configure your Agent to be a phone calling maestro! You can set up your Agent to perform outbound calls, where it leverages your Agent’s configured Tools in real-time during the call.
How do I change my agent to the Phone Agent mode?
You can create a new Phone Agent, or convert your normal Agent to a Phone Agent. To convert your normal Agent to a Phone Agent, follow these steps.
- Open your Agent, and click ‘Advanced’ to head to your Advanced Settings
- Then, click ‘Phone Call’ on the Agent mode dropdown
- Then, head to the new ‘Phone Mode’ section in the sidebar to configure your Settings
In order for your Agent to work, it’ll need to be part of a multi-agent system, where a Parent agent will send it info such as a number to call, info about the customer they’re calling, etc. We recommend using a Workforce to do this.
