How is this different from a service like Ruby Receptionists?

Ruby is excellent at the human-receptionist tier. Open is the AI tier — it resolves routine calls in-call rather than passing every message to you. The two can coexist (AI for routine, human for complex), or AI can replace the service entirely depending on your call mix.

How much does it cost?

Per-resolution pricing starting at around $99/month for typical small-business volume. No setup fee, no per-seat, no minute charges. You only pay when the AI resolves something.

Will customers know it's AI?

Most don't on the first call. The voice quality is natural, the conversation is grounded in your business and CRM, and the AI doesn't try to spoof being human if asked directly.

Does it work with my existing phone number?

Yes. Open is a SIP / forwarding destination — your number stays on your existing carrier (Twilio, RingCentral, Vonage, OpenPhone, Aircall, Grasshopper, etc.) and Open just answers the call.

How fast can I get started?

Same day. Most small businesses run their first test call within an hour and go live with production traffic within 24 hours.

What happens if the AI can't handle a call?

It pages you (SMS, Slack, voice transfer) with the live transcript and detected intent. You configure the rules: when to escalate, who to escalate to, what to do if no one's available.

01 — Overview

What's the right answering service for a small business in 2026?

For most small businesses: an AI receptionist that resolves the routine 80% of calls instantly and pages you on the 20% that actually need you. Open is per-resolution priced, lives in a day, and works with whatever phone, calendar, and CRM you already have.

Small-business owners pay one of three prices for phone coverage. Hire a part-time receptionist ($25-40k/year). Pay a premium answering service ($300-$1,200/month per line). Let calls go to voicemail and lose the customer. None of those is great. The first is overkill for most volume; the second is expensive for what you get; the third is the most expensive in lost revenue but the easiest to ignore.

Open's AI receptionist is the fourth option. It answers every call in under two seconds — your business name, your brand voice, in the language the caller speaks. It pulls the caller's record from your CRM (HubSpot, Salesforce, Pipedrive, generic CSV) by phone number, runs the conversation, and resolves what it can: book the appointment, take the message, send the payment link, route to the right person.

Setup is same-day. Connect your existing phone (Twilio, RingCentral, Vonage, OpenPhone, Aircall, Grasshopper, Google Voice for Workspace), point at your calendar (Google Calendar, Outlook, Calendly, Acuity), set the agent role and brand voice, ship. The first test call usually happens within an hour.

Pricing is per resolved conversation. You pay when the AI actually does something — books an appointment, answers a question, takes a payment, resolves a ticket. You don't pay for missed calls, voicemails, wrong-number calls, or calls where the AI couldn't help. For most small businesses this lands 60-85% below the cost of a traditional answering service.

Compliance: TCPA-aware out of the box, configurable consent prompts, opt-out handling automatic, recording configurable. The AI never spoofs being a human if asked directly.
