Looking for the best AI answering service?

Missed calls driving you crazy? You're not alone. We all get frustrated by ringing phones and voicemails piling up. There just aren't enough hours in the day to return every call.

But what if you had an AI virtual assistant answering phone calls for you? 

Conversational IVR systems with AI technologies like NLU, NLG, and TTS can help automate customer service interactions, freeing up agents for more valuable interactions and enabling complex, two-way conversations with customers, even during tricky collections calls, as seen with ING Bank.

After implementing this technology, ING Bank saw a 50% decrease in agent workloads and a nearly 60% increase in customer payment promises. [1]

This shows the potential benefits of AI-powered phone answering systems for businesses looking to improve customer support and efficiency.

Why Simple Phones is My Top Recommendation for AI Phone Answering?

As a business owner, I became increasingly overwhelmed trying to handle all my incoming calls. Between answering customer questions, booking appointments, and responding to inquiries, it was impossible to be available 24/7.

I tried many solutions - call forwarding, hiring staff - but nothing truly optimized our phone system.

Calls inevitably slipped through the cracks, leading to missed opportunities and frustrated customers.

That's when I discovered Simple Phones. After thoroughly researching AI phone answering services, Simple Phones stands out as my top recommendation. Here's why:

Easy Onboarding

Creating an AI agent took me less than 60 seconds right from their website. Without any technical skills, I customized a virtual receptionist to handle our exact business needs.

Seamless Call Handling

The AI seamlessly handles a wide array of caller needs - inbound and outbound calls, answering FAQs, booking appointments, taking messages, transferring calls, and more. It sounds completely natural having everyday conversations.

Robust Customization

I can customize everything - the virtual agent's voice, scripts, call routing, and integrations. Whenever I need tweaks, Simple Phones immediately implements them.

Helpful Features

Features like call logging, voice crawling web content, outbound calling, and real-time testing have made a big difference. My AI assistant improves every day.

Flexible Number Options

I easily kept my existing business number by forwarding missed calls to Simple Phones' number. They assign a new number if needed.

Wide Language Support

Simple Phones offers numerous language and accent options for live chat support. My AI agent handles English, Spanish, and French callers seamlessly.

Simple Phones also makes it easy to integrate their AI phone answering system with your existing CRM or back-end system. This ensures that customer requests are fulfilled and information flows to the right place. 

Plus, they can work with popular tools like Zapier to send webhooks in a format that works for you, making it easy to manage customer information and streamline your workflow.

I hope that answers your questions about why I think Simple Phones is pretty awesome. But hey, don't just take my word for it.

You can start a 14-day free trial and see how it works for yourself. 


One of the great things about Simple Phones is that pricing is straightforward, with no hidden fees. Plans start at $49/mo for 100 calls/mo. This basic plan is perfect for small businesses just getting started with an automated answering service.
