Voice AI Receptionist
A real-time AI agent that picks up your phone, books appointments, and routes the calls that need a human.
What it is
Here's the short version.
A Voice AI Receptionist from PerezCarreno & Coindreau is a production-grade AI phone agent that picks up your phone, books appointments, answers questions, qualifies leads, and routes the calls that need a human. It is integrated with your calendar and CRM, trained on your business specifics, and runs 24/7 in English and Spanish. Setup takes 2 to 4 weeks and includes a custom voice, a scripted knowledge base for your business, calendar integration, human-handoff rules, and CRM + SMS follow-up automations. Built for small and medium businesses that lose revenue to missed calls (auto shops, dental, medical, home services, professional services). Typical clients recover 20 to 40% of previously missed calls within the first month.

FAQ
Voice AI Receptionist: questions we hear
- How natural does it actually sound?
-
Natural enough that most callers do not realize they are speaking with an AI, until we tell them, which we recommend doing. The voice AI uses current-generation models from ElevenLabs, OpenAI, or similar, and handles interruptions, mispronunciations, background noise, and accented English. We tune the voice to match your brand and industry tone.
- What can it handle without escalating to a human?
-
Appointment scheduling, rescheduling, and cancellations; answering common questions (hours, location, services); taking messages and detailed inbound requests; qualifying inbound leads; routing calls by topic; basic billing and account lookups if integrated with your system. Complex or emotional conversations always route to a human with full context.
- What does this cost to run per month after setup?
-
Operational cost depends on call volume, voice provider, and how much logic is handled on your side versus in the AI. We bill a one-time setup plus a monthly support retainer, both quoted after a free discovery call. Third-party usage (voice minutes, LLM tokens) is billed at cost or directly to your account, with no markup.
