How AI phone calls work with Sona

Sona uses advanced AI technology to understand caller requests and respond using the knowledge you provide. When a call reaches Sona in your call flow, it answers the call, introduces itself, listens to the caller, and provides information or takes a message.

Add Sona directly in your call flows with our call flow builder. You can edit Sona’s greeting message and customize what you want Sona to do when it receives an incoming call. 

Want Sona to handle follow-up questions, too? You can have Sona: 

  • Request specific information based on what the caller is saying; for example, Sona can ask for their preferred time frame for a callback if a caller indicates their request is urgent
  • Greet callers differently depending on where you add Sona in your call flow, like after-hours vs during business hours. For example, you can set a specific greeting from Sona that starts by informing callers when they reach you outside working hours
  • Reference specific knowledge documentation based on a phone menu option callers select; for example, if a caller presses one for sales, you can provide information based on the frequently asked questions your sales team receives  

With OpenPhone’s business phone and AI features, you won’t need to switch between multiple apps. Sona calls appear in your conversation history with a transcript and summary so that you and your team have all the context you need to follow up over the phone. It’s why we’re the #1 rated business phone system as voted by thousands of growing businesses.

What is an AI phone call?
down arrow

An AI phone call is a call managed by an AI phone agent or an AI voice agent. AI agents use natural language processing and large language models to communicate with callers and address their needs.

AI phone agents give small and growing businesses the ability to answer incoming calls 24x7 without having to rely on an external call center. They can deliver a professional after-hours customer experience that assists team members with satisfying customer needs. 

How does OpenPhone automate phone calls with Sona?

3. Take a message: Sona can take detailed messages from customers by capturing why they called and asking follow-up questions based on common customer requests. For example, if you’re a healthcare business that needs help with appointment scheduling, Sona can gather which days and times a patient is available for an appointment.

Keep in mind Sona can’t make outbound calls right now, so you can’t use it for external outreach.
