Voice receptionist sounds remarkably human on inbound calls.
Booked three client appointments on day one automatically.
Saved our small business from missing weekend leads.
Occasional weird phrasing on complex industry terms.
AI-synthesized perspectives grounded in live site inspection, pricing structure, and category benchmarks — presented as editorial viewpoints rather than individual customer testimonials.
Agents answer inbound calls instantly at any hour, hold natural conversations, and capture the details that matter for each caller.
18 supported industries (plumbing, HVAC, real estate, property management, salons, legal and more) come with pre-filled pricing, vocabulary, and urgency rules.
Agents book appointments directly into your calendar, send real-time transcripts and summaries, and flag urgent calls for immediate follow-up.
A REST API and TypeScript SDK let you create agents, provision numbers, fetch transcripts, and subscribe to call events to embed voice agents in your own product.
Resell OnCallClerk under your own brand, manage multiple client numbers from one dashboard, and keep the margin between your price and the platform cost.
OnCallClerk is an AI receptionist platform aimed at small businesses and service trades that cannot afford to miss calls. You pick an industry, choose a voice, and connect a local or toll-free number (or forward an existing line); a setup wizard fills in pricing and answers so an agent can be live in about an afternoon. The agent answers instantly with a natural voice, captures caller details, books straight into a calendar, and triggers instant alerts for urgent calls.
The product is tuned per vertical: plumbing, HVAC, real estate, property management, salons, legal, auto repair and more get their own vocabulary and urgency rules. Callers get consistent answers and your team gets real-time transcripts and structured summaries instead of voicemail. It advertises English and Spanish handling out of the box.
Beyond the dashboard, OnCallClerk exposes everything over a REST API plus a TypeScript SDK, and offers white-label reselling so agencies can run client numbers under their own brand. Plans start at $29/month with a 14-day free trial and pay-per-answered-call billing; no setup fees or contracts are advertised.
A plumbing or HVAC company routes urgent calls to the on-call technician and books non-urgent jobs for the next day, so high-value emergency call-outs are not lost to voicemail.
The agent picks up instantly, qualifies a buyer's timeline and budget, and books a showing or callback while the lead is still warm.
Use the API, SDK, and white-label options to provision AI receptionists for multiple clients and resell them under your own brand.
