FREQUENTLY ASKED
QUESTIONS

Frequently Asked Question

What is voice AI for a service business?

Voice AI is a call-handling and lead-capture system that can answer inbound calls, ask qualifying questions, route urgent requests, and book appointments. It is most useful when your team misses calls, responds slowly after hours, or needs cleaner intake.

Frequently Asked Question

Can voice AI answer calls and book appointments?

Yes. We design call flows that answer common questions, collect intent, qualify the caller, and book directly into your calendar or hand off to the right person.

Frequently Asked Question

How does voice AI connect to my CRM?

We connect voice AI to CRMs, GoHighLevel, calendars, and follow-up automations so transcripts, call outcomes, appointments, and lead data sync automatically.

Frequently Asked Question

How much does a voice AI system cost?

Voice AI projects typically start around $20,000 for a focused production setup. More advanced systems with multi-step qualification and deeper integrations range higher.

Frequently Asked Question

When should I use voice AI instead of live staff?

Voice AI works best for first response, after-hours coverage, overflow, repetitive intake, and routine qualification. Live staff still matter for nuanced sales conversations and sensitive situations. The best setup is often AI plus human handoff.

Frequently Asked Question

How quickly can you launch a voice AI workflow?

A focused voice AI workflow can launch in a few weeks. More complex systems with integrations, testing, multiple intents, and fallback logic take longer. We roll out in phases so lead capture starts improving early.
