Retell is a platform for building a voice agent. Central is the voice agent, already built.
Stop setting up infrastructure. Start answering calls.
Never miss another call.
The goal isn't a developer toolkit. It's a front desk that works.
Retell AI is a developer infrastructure platform. It is API-first, modular, and technically impressive: low latency, natural-sounding voices, and the flexibility to build almost any voice workflow you can imagine. Developers love it. Engineering teams at companies like Anker and Lenovo use it to build custom voice pipelines at scale. If you have a developer and weeks to configure it, Retell is a capable foundation.
If you run a dental practice, a law firm, a home services company, or a real estate office, Retell was not built for you. Independent reviewers describe it plainly: it is "infrastructure code intended for technical teams to build upon, not a turnkey solution" for service business front desks.
Central was. You paste your website URL, connect your calendar, and Central starts answering calls. No API. No webhooks. No LLM selection. No developer required.
No commitment
No migration required.
Retell wasn't built for your business. It was built for your developer.
Getting a working Retell agent into production means selecting your LLM, configuring your voice engine, setting up telephony integrations, writing prompt logic, and wiring webhooks to your calendar and CRM. For a software team building a voice product to sell to others, that control is the whole point. For a business owner who just needs their phones covered, it is weeks of work before the first call is answered, and ongoing developer involvement every time something needs to change.
The pricing compounds it. Retell advertises $0.07 per minute, but that is the voice engine rate only. Add your LLM, your telephony, and any add-ons, and real-world all-in costs consistently run $0.13 to $0.31 per minute, two to four times the headline figure. Multiple independent reviews document the same pattern: the first invoice arrives and the actual cost is a surprise.
And when something goes wrong on your phone line, Retell's primary support channel is a community Discord. Ticket response times are frequently flagged as slow. For a business where every missed call is a missed lead, that support model is a risk, not a feature.
What this means in practice:
Getting your first call answered requires developer setup: API configuration, prompt engineering, webhook wiring, telephony integration
Retell has no native CRM integrations; connecting to HubSpot, your calendar, or any other tool requires API calls or Zapier
The real all-in cost is $0.13 to $0.31 per minute, not the $0.07 advertised as the base rate
When something breaks, your primary support option is a community Discord forum
Retell's own blog states the platform is "not a standalone app for business owners"
Central reads your business. Then it answers your calls.
Central connects to your website and calendar and starts handling calls the same day you sign up. No developer. No configuration. No invoice that surprises you at the end of the month.
Every call that comes in becomes an outcome delivered.
Your front desk stops being something you build and starts being something that runs.
What this means in practice:
A new inquiry arrives and Central answers it, qualifies the caller, and logs the lead automatically
A booking request comes in and Central checks your calendar and confirms the appointment during the call
A caller goes off-script and Central transfers to a live team member automatically, no API required
Post-call summaries are waiting for you after every conversation
Your monthly cost is fixed before the month starts, regardless of how long your calls run

Starting Central does not require unwinding what you built in Retell, because there is nothing to unwind. Central is a completely separate system. You connect your website URL and calendar, set your call preferences, and Central starts handling calls.
There are no API calls to write. No webhooks to configure. No LLM to choose. Most businesses are live the same day they sign up.
There's no switching cost. There's no technical debt. There's just the moment when your phones start being handled by something that was built for your business, not for someone else's developer team.

Don't take our word for it
"I tried setting up Retell myself and got stuck immediately. Everything required API calls I didn't know how to make. I was quoted a rate of $0.07 per minute but by the time I added everything up it was closer to $0.25. I switched to Central, pasted my website URL, and was live the same afternoon. It's been answering my calls ever since."
