Sona is a feature. Central is a front desk.
Stop working around a feature. Start using a front desk built for the job.
Never miss another call.
One is a feature. One is built for this.
Quo is a well-built business phone system. Sona, its AI receptionist, launched in April 2025 as a way to handle calls inside the Quo platform. For teams already in Quo who want basic AI call answering, it works. It is a good feature inside a good phone product.
Central is not a phone system. It is a dedicated AI receptionist. No phone plan required, no per-call overage, no English-only ceiling.
No phone subscription
No per-call billing
No commitment required.
Add-on pricing. Add-on limitations.
Sona is priced per call, on top of a Quo subscription. It is English only. Appointment booking connects to Google Calendar only. And you cannot trial Sona before committing to a Quo phone plan.
What this means in practice:
Sona at 100 calls costs $49/month on top of your Quo subscription ($19 to $47/user/month), totaling $68 to $96/month
At 200 calls, combined cost is $98 to $126/month, with per-call billing that varies every month
Spanish-speaking and multilingual callers receive an English-only response
Calendly and Cal.com are not supported; Google Calendar only
You must commit to a Quo phone plan before you can test the AI receptionist
Any language. Any calendar. Flat rate.
Central connects to your website and calendar and starts handling calls the same day. No phone subscription. No per-call math. No language ceiling.
Every call that comes in becomes an outcome delivered.
What this means in practice:
Callers answered in any language, leads logged automatically
Appointments confirmed during the call into Calendly, Cal.com, or Google Calendar
Human transfer triggers automatically, no configuration required
Post-call summaries ready after every conversation
Fixed monthly cost regardless of call volume or length

Don't take our word for it
"Sona wasn't cutting it: English only, per-call billing, no Calendly. We kept Quo for our team lines and switched to Central for inbound calls. Every caller gets helped in their language, every appointment goes into our calendar, and I know exactly what I'm paying."
