Human warmth vs. predictable cost.
Ruby is a premium US-based answering service with a two-decade track record in legal, medical, and professional services. Its receptionists are trained, empathetic, and professional. For businesses where human warmth is part of the brand, that service has real value.
Central is an AI receptionist with a flat monthly rate. It answers every call, books appointments, logs leads, and transfers to a live person when needed. The cost is the same whether you take 50 calls or 200. No per-minute clock. No overage.
No per-minute billing
No commitment required.
Per-minute pricing adds up fast.
Ruby bills by the minute in 30-second increments. Overages apply when you exceed your plan's minutes. After-hours and holiday coverage cost extra. Hang-up calls are charged at 30 seconds each. There is no free trial. Plans run $129 to $999/month before any of those additions, and the bill changes every month based on how much your phones ring.
What this means in practice:
Every minute of every call counts against your plan; overages billed at per-minute rates
Hang-up calls charged at 30 seconds per occurrence
After-hours and holiday coverage available at premium rates above standard plan cost
No bilingual receptionists for Spanish-speaking or multilingual callers
No free trial; commitment required before you can test the service
Same cost. Every month.
Central connects to your website and calendar and starts answering calls the same day. The price does not change when things get busy.
What this means in practice:
Every call answered, every lead logged, every appointment booked automatically
Human transfer triggers when a caller needs a real person, no configuration required
30+ languages supported on all plans, no add-on required
$79, $149, or $299 per month. No minute tracking. No hang-up charges. No surprises.

Don't take our word for it
"Ruby's receptionists were great, but the bill was different every month. Busy weeks meant overages I hadn't planned for. I switched to Central and now I know exactly what I'm paying. Every call handled, every appointment booked, flat rate."
