Hi, do you guys do upholstery cleaning?

Questions

Everything you need to know.

How does MasterVox work?
MasterVox uses best-in-class conversational AI to answer phone calls in a natural, human-like voice. You train it on your business by pasting your website URL, and it learns your services, hours, pricing, and FAQs. When a customer calls, the AI picks up instantly, answers their questions, and can book appointments directly into your calendar.
What happens when my minutes run out?
Your agent will continue to answer calls. Additional minutes are billed at a per-minute rate. You can also upgrade your plan at any time to get more included minutes. We'll notify you when you're approaching your limit.
Can the AI book real appointments?
Yes. MasterVox integrates directly with Google Calendar and GoHighLevel (GHL). When a caller wants to book, the AI checks live availability and creates a confirmed appointment — no human needed.
Is there a contract?
No contracts, ever. All plans are month-to-month and you can cancel anytime. Paid plans also include a 7-day free trial so you can verify it works for your business before you're charged.
What integrations are supported?
MasterVox integrates with GoHighLevel (GHL) and Google Calendar, and sends carrier-grade SMS follow-ups after every call. Additional integrations (Calendly, Salesforce, HubSpot) are on our roadmap.
How long does setup take?
Most businesses are live in under 5 minutes. You paste your website URL, the AI reads your content and builds your agent, and you assign a phone number. That's it.
Can I use my own phone number?
You can port an existing business number to MasterVox or use one of our local numbers. Number porting typically takes 3–7 business days. New numbers are available instantly.
Is call data secure?
Yes. All calls are encrypted in transit and at rest. We comply with applicable data privacy laws. Call recordings and transcripts are stored on enterprise-grade infrastructure and are only accessible to your account. You can delete any data at any time from your dashboard.

Every missed call is a missed sale. MasterVox answers 24/7 so you never leave money on the table.
