NEW — AI-Powered

AI Voice Agent for Your Phone System

Never miss another call. Our AI voice agent answers your business calls 24/7 with a natural, human-like voice — handling inquiries, booking appointments, taking messages, and transferring to your team when needed.

What Is an AI Voice Agent?

The end of "press 1 for sales, press 2 for support"

Not Your Old-School IVR

Traditional IVR systems force callers through rigid menu trees — "press 1 for sales, press 2 for support." Callers hate them, and they cost you business. An AI voice agent replaces all of that with natural, free-flowing conversation. Callers simply say what they need, and the AI understands.

Real Conversation, Not Scripts

Powered by advanced speech recognition, natural language processing (NLP), and neural text-to-speech, our AI voice agent understands caller intent, asks follow-up questions, and responds in a warm, natural-sounding voice — just like a well-trained receptionist.

Built for Business Owners

You don't need any technical knowledge. We configure the AI to understand your business, your services, your hours, and your team. It handles the calls you can't — after hours, during lunch, when lines are busy — so you never lose a lead or frustrate a customer.

How It Works with Your Phone System

Connects to FreePBX, Asterisk, FusionPBX, 3CX, or any SIP system

1

Call Arrives at Your PBX

An inbound call reaches your phone system — FreePBX, Asterisk, FusionPBX, 3CX, Cisco UCM, or any SIP-compatible PBX. Your existing phone numbers and routing stay exactly as they are.

2

PBX Routes to VoipOver AI Agent

Your PBX forwards the call to VoipOver's AI endpoint via a standard SIP trunk. You choose when the AI handles calls — all calls, overflow only, after-hours only, or specific departments.

3

AI Answers with Your Custom Greeting

The AI picks up instantly with a personalized greeting for your business. Choose from natural-sounding female or male voices. It sounds like your best receptionist, not a robot.

4

Caller Speaks Naturally — AI Understands

No menus, no button presses. The caller says what they need — "I'd like to schedule an appointment," "I need to speak with billing," "What are your hours?" — and the AI understands the intent instantly.

5

AI Responds, Acts, or Transfers

Based on the caller's request, the AI can answer questions, take detailed messages, book appointments directly into your calendar, or warm-transfer the call to a live team member.

6

You Get Transcripts, Recordings & Analytics

Every call is transcribed in real time. You receive transcripts and summaries via email or SMS. A full analytics dashboard shows call volume, common requests, resolution rates, and more.

Frequently Asked Questions

Everything you need to know about our AI voice agent

What voices are available?
We offer a selection of natural-sounding neural voices, including multiple female and male options. Each voice is designed to sound warm, professional, and conversational — not robotic. You can preview all available voices during setup and choose the one that best represents your brand. Custom voice cloning is available on enterprise plans.
Can the AI handle complex conversations?
Yes. Our AI voice agent uses advanced natural language processing to understand context, follow multi-turn conversations, ask clarifying questions, and handle nuanced requests. It can manage appointment scheduling with multiple date/time options, collect detailed intake information, answer FAQs about your business, and more. For truly complex situations, it seamlessly transfers to a live agent with full context.
What happens if the AI can't help a caller?
The AI is designed to recognize when it can't resolve a request. In those cases, it offers to transfer the caller to a live team member, take a detailed message for callback, or provide alternative contact methods. You configure the escalation rules — so you're always in control of what happens when the AI reaches its limits.
How does it integrate with FreePBX?
Integration is straightforward. You add a SIP trunk in your FreePBX admin panel pointed at our AI endpoint (we provide the server address and credentials). Then you create or modify an inbound route to send calls to that trunk. The entire process takes under 30 minutes, and our team will walk you through it or do it for you remotely. It works the same way with Asterisk, FusionPBX, 3CX, and any other SIP-compatible system.
Does it work with my existing phone number?
Absolutely. You keep your existing phone numbers. The AI agent sits behind your PBX, so calls come in on your current numbers and get routed to the AI via your internal dial plan. There's no need to port numbers or change anything your customers see. Your caller ID remains the same.
Can I customize the greeting and responses?
Every aspect of the AI's behavior is customizable. You control the greeting, the voice, the personality tone (formal, friendly, casual), business-specific knowledge (services, hours, pricing, staff names), call-handling rules, and escalation procedures. We work with you during onboarding to get everything dialed in, and you can make changes anytime through our dashboard or by contacting support.
Is there a free trial?
Yes, we offer a 14-day free trial so you can experience the AI voice agent with your real call flow before committing. The trial includes full access to all features, custom configuration, and our setup support. No credit card required to start. Contact us to get started.
What languages are supported?
Our AI voice agent currently supports English (US and UK), Spanish, French, German, Portuguese, Italian, and Mandarin Chinese, with more languages being added regularly. The AI can detect a caller's language preference automatically and switch accordingly, or you can set a default language per inbound route. Bilingual greetings (e.g., English/Spanish) are also available.
How is call quality and latency?
We run our AI infrastructure on low-latency servers optimized for real-time voice processing. Response times are typically under 500 milliseconds, making conversations feel natural and fluid. Combined with VoipOver's 99.9% uptime fiber network, you get crystal-clear call quality and reliable performance around the clock.
Is my data secure?
Yes. All calls are encrypted in transit (TLS/SRTP). Call recordings and transcripts are stored securely with encryption at rest. We are compliant with industry standards for data protection. For healthcare clients, HIPAA-compliant configurations are available on our enterprise plans. You can also set automatic data retention policies to delete recordings after a specified period.
