SimpleVoIP is an AI phone answering service for small businesses. Instead of paying $22–27/hour for a call-center agent, you get five full-time AI phone agents working 24/7 for $99/month — no setup fee, and a free 30-day trial.

The AI answers inbound calls in fluent, unaccented English and Spanish (plus 20 other languages), speaking naturally with callers. It learns your business facts from your website and manuals and answers 50–90% of calls right out of the box. When it hits a question it can't handle, it transfers the caller to a human — no hold music for simple stuff, no wasted agent time.

What makes it different: it learns on the job. When a call goes to a human agent, the system studies how your best people handle the hard questions — tone, reasoning, de-escalation — and adds that to its knowledge base, so it handles more over time. You also get a printed transcript of every call.

Setup is one step: use the US phone number included, or forward your existing number. Try the live demo at 877-692-4004.

Questions & Answers

As answered by people managing Manus and SimpleVoIP.dev.

What makes your product unique?

SimpleVoIP.dev's answer:

It learns on the job. When a call goes to a human, SimpleVoIP studies how your best agents handle hard questions — tone, reasoning, de-escalation — and adds it to the knowledge base, so the AI handles more over time. You also get a printed transcript of every call.

Why should a person choose your product over its competitors?

SimpleVoIP.dev's answer:

Price and simplicity. Five AI agents working 24/7 for $99/month flat — no per-minute fees, no setup fee, free 30-day trial. It answers in fluent English and Spanish (plus 20 languages), works out of the box by learning from your website, and hands off to a human when needed.

Which are the primary technologies used for building your product?

SimpleVoIP.dev's answer:

Conversational AI / large language models for natural speech, speech-to-text and text-to-speech for real-time voice, and VoIP/telephony for call handling and human transfer.

How would you describe the primary audience of your product?

SimpleVoIP.dev's answer:

Small and mid-sized businesses that miss inbound calls or can't justify $22–27/hour for call-center staff — clinics, service businesses, agencies, and shops that need every call answered 24/7 in English and Spanish.

What's the story behind your product?

SimpleVoIP.dev's answer:

SimpleVoIP was built so small businesses could afford to answer every call. Hiring round-the-clock staff is expensive and missed calls are lost customers, so we created AI phone agents that answer naturally, learn each business from its own website, and get smarter every time they hand off to a human.

Who are some of the biggest customers of your product?

SimpleVoIP.dev's answer:

  • Small businesses and clinics using AI to answer calls 24/7
  • Spanish-and-English service businesses needing bilingual phone coverage
  • Companies replacing or supplementing a traditional answering service
