How AI voice answering works

Rezi answers phone calls to your building number with a natural-sounding AI that can screen, quote, and book.

Updated June 9, 2026 3 min read

The same building number that handles texts also handles calls. When someone calls, Rezi answers with a natural voice, understands what they need, and helps, 24/7, no hold music.

Phone calls skew toward a particular crowd: older guests who never text, travelers who want to hear a voice before they trust a listing, and anyone in a hurry or mid-crisis. Historically those calls either interrupted your day or went to voicemail, and voicemail is where bookings go to die. AI voice answering means every call gets picked up on the first rings, every time, without your phone ever buzzing.

The conversation itself is genuinely conversational, not a phone tree. There’s no “press 2 for billing”; the caller just talks, the AI understands, asks follow-ups where needed, and handles interruptions and topic changes the way a person would. Most callers simply experience a competent helper who happens to never be busy.

What the voice AI can do

  • Greet callers and identify your property
  • Answer questions from the same knowledge base it uses for texts
  • Quote availability and nightly rates from your synced calendar
  • Walk guests through check-in and checkout
  • Escalate or take a message when a human is needed

Those capabilities chain together naturally within one call. A traveler can ask about the pet policy, hear the nightly rate, check whether their dates are open, and get pointed to your booking link, no callback, no “someone will reach out.” A guest can report a leak and have you alerted before they hang up, with the same emergency rules that govern texting.

One brain, two channels

Voice and text share the same knowledge base and the same built-in assistant identity, so a caller and a texter get consistent answers in one consistent voice.

What you see afterward

Every call lands in the Interactions view alongside your text threads, with a full transcript, the caller’s number, the time, and the outcome, answered, message taken, or escalated. Calls that need you follow the same escalation paths as texts, so a 2am emergency call rings your on-call contact, not just your dashboard.

Turning it on

Voice answering is enabled per building, so you can roll it out property by property. To turn on call answering, follow setting up inbound voice, it takes a few minutes, and the most important step is placing a test call yourself before guests do.

Does the voice sound robotic?
No, modern AI voices are natural enough that most callers don’t think twice. The greeting names your property and assistant, and the conversation flows at normal speed with normal pauses.
What happens if the caller has a thick accent or bad connection?
The AI handles accents and imperfect audio well, and asks for clarification rather than guessing when it genuinely can’t make something out, the same grounded behavior as texting.
Can it speak languages other than English?
Yes, callers are helped in their own language. See what languages can Rezi speak on calls.
Can callers still reach a human?
Always. Saying “I want to talk to a person” triggers your configured escalation, forwarding to your phone or taking a detailed message.
