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.
