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.

AgentClara's answer:
Most AI receptionists answer the phone. Clara staffs the whole front desk: she answers every call 24/7, books clients straight into your live diary, chases enquiries that didn't book, and covers your website chat, SMS, social media inbox and email — with those extra channels included free, not sold as add-ons. She's UK-built, GDPR-native, priced in pounds, and you set her up yourself online in minutes with a free number and £100 of credit — no sales call, no quote.
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.
AgentClara's answer:
Three reasons. First, channels: rivals are phone-first, so DMs and web chat go unanswered — Clara covers every channel in one place. Second, booking: many entry plans only take messages or send a booking link; Clara books the appointment during the call and sends the confirmation. Third, no sales process: the big UK incumbents quote you after a consultation, while Clara is self-serve with £100 of free credit so you can test her on your real calls before paying anything.
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.
AgentClara's answer:
A React and TypeScript web application on a Postgres backend, with real-time voice handled over a persistent WebSocket bridge for low-latency conversation. Large language models power the conversational layer, with dedicated speech and telephony infrastructure for calls, plus integrations for calendars, messaging channels and payments.
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.
AgentClara's answer:
UK service businesses that lose money to missed calls — gyms, salons, aesthetics clinics, dental practices, estate agents and law firms — where one missed enquiry is a lost booking worth hundreds. The second audience is agencies and resellers who want to offer AI receptionists to their own client book without building the technology themselves.
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.
AgentClara's answer:
AgentClara was built by a Glasgow gym owner who kept losing members to unanswered calls. The phone rang mid-class, the Instagram DM arrived at 10pm, and the customer joined the gym down the road — not because the service was worse, but because nobody answered. Clara was built to be the employee that always answers, and now does the same job for service businesses across the UK.
