3 powerful use cases for your AI voice agent

Sona can take these key tasks off your team's plate when you're unavailable:

1. Answer common questions

Sona answers common customer questions so your team can handle more complex requests. Train Sona on your company policies, and it can provide the right answers to customers on your team’s behalf. 

2. Take detailed messages

Wish you had more context from customers who leave a voicemail? Sona takes detailed messages so you have the information you need. It can even ask callers follow-up questions based on the reason for their call.

3. Capture leads

For new callers, Sona can be prompted to ask for their information and record whether they’re interested in entering a sales conversation. Once they capture the caller’s name, company, and role, OpenPhone AI can automatically suggest a new contact so that your address book is updated. 

Handle more incoming calls with an AI voice agent

Smarter than voicemail. More affordable than a traditional answering service.

Add Sona to existing workflows

Unlike many other voice agents, Sona requires no code to get started. Simply drag and drop Sona into your existing call flows. You can use Sona along with our call routing features like phone menus, ring order, and call forwarding.

Train Sona to handle phone calls

Our AI agent, Sona, can handle your incoming calls when your team is busy or unavailable. Sona can also answer common questions after being trained on your documentation. Plus, take detailed messages from customers so your team can have more informed conversations when they call back.

Take detailed messages with follow-ups

Get Sona to request specific information based on keywords during the call. That way, your team is better equipped to follow up and continue the conversation. 

Automate call logs with CRM integrations

View Sona’s call summaries, transcripts, and messages in your OpenPhone inbox right after a call ends. Sync call data to your CRM of choice — use our native HubSpot and Salesforce integrations or build a custom integration with the OpenPhone API.

What does a voice agent do?
down arrow

AI voice agents provide basic customer service to callers by answering questions or taking messages. They’re the voice equivalent of a digital chatbot. By using AI phone calls to have natural conversations, voice agents can provide a high-quality experience to your customers. 

What is the best AI voice agent?
down arrow

The best AI voice agent depends on your business needs. If you run a healthcare business, your AI voice agent might require HIPAA compliance. If you provide service to customers in multiple countries, your AI answering service might require multilingual support to work for you. 

Sona is the best AI voice agent for small and growing businesses. It reduces your missed calls, answers common customer questions, and takes detailed messages that make customer communication more efficient for your team.

How does an AI voice agent work?
down arrow

An AI voice agent combines multiple artificial intelligence (AI) and voice processing technologies to speak to callers. Here’s a summary of some of the technologies it uses to have a conversation:

1. When a call comes in, the agent uses speech recognition and speech-to-text software to convert a caller’s voice into text. Then the agent uses natural language processing (NLP) to understand what a caller said. 
2. Next, it uses large language models (LLMs) to collect information from its knowledge base to formulate a response. 
3. Finally, using text-to-speech software (TTS), the agent converts text responses into audio and relays a response to the caller. 

The best conversational AI voice agents execute these tasks with low latency so they can provide an optimal customer experience.

Can Sona and AI voice agents replace my sales and support teams?
down arrow

At this time, Sona and AI voice agents can’t perform all the functions of a sales or customer support team. For example, if you need to return an order or get a sales demo, an AI voice agent can’t handle those tasks yet. 

Dedicated sales AI or customer support AI tools are still limited in how much they can do for your team. AI receptionists are great at assisting existing teams by handling additional inbound call volume when your team is busy or away for the day. However, they can’t entirely replace human agents. 

What happens if my AI agent can’t answer a question?
down arrow

If Sona can’t answer a question, it will communicate the limitation to the caller and offer to take a message for a human team member to follow up.
