Independent setup · Dental practices
We test 8 voice agents on real calls, then set up the one that wins for your practice
Cozzo runs public benchmarks of AI phone agents. We’ll use the same tests on your own office script, set up the agent that passes, and keep checking it every month.
The problem: every missed call can be a missed patient
Front desks are busy. Calls during treatment, lunch and after hours go to voicemail, and a new patient who can’t get through may just call the next office on the list.
AI receptionists can answer every call, but they aren’t all equal. In our test calls some invented appointment times, misread phone numbers, or kept talking over the caller. Picking one from a demo is a gamble.
Why use someone neutral
We don’t sell an agent
Vendors recommend their own product. We set up whichever one passes on your script.
Decisions from test calls
The pick comes from recorded calls scored pass/fail, not a demo.
Published method
Our test battery and results are public, so you can check our work.
Proof: what round 4 found
We called 8 voice agents with the same dental-receptionist prompt, 3 calls per scenario. See the full round 4 results.
- No agent read the callback number back correctly on all 3 tries. The best managed 2 of 3.
- Bland kept talking for 2.68 s after the caller cut in, over our 2.0 s limit.
- ElevenLabs was fastest, with a 1.06 s median reply.
- Ultravox
- LiveKit (self-hosted)
- ElevenLabs
- Vapi
- Bland

- LiveKit (self-hosted)2.00 s
Three calls per scenario is a small sample: treat these as patterns to check, not a final ranking.
How it works
- 1
Audit
We listen to how your phones are answered today: missed calls, after-hours, common requests, and what your booking software can connect to.
- 2
Shortlist
We pick the 2–3 agents from our benchmarks that fit your call mix, budget and integrations.
- 3
Private test on your script
We run the shortlisted agents through our call battery using your office’s hours, services, insurance list and emergency policy, with fictional caller data.
- 4
Setup
We configure the winner on your own platform account: prompts, knowledge, call transfer, and booking integration where supported.
- 5
Go-live QA
Before your number points at it, we re-run the tests on the final setup and only sign off when it passes.
Monthly QA
Agents change when platforms update models. Every month we call your live agent with fictional patient details and run the same checks we use in our benchmarks.
✓ Booking + read-back
Books only real slots and reads back the caller’s name and callback number exactly. One wrong digit is a fail.
✓ Reschedule
Offers only real availability; never invents a time.
✓ Unknown insurance + callback
Doesn’t claim to accept a plan you don’t take; takes a callback or message correctly.
✓ Interruptions
Stops talking within 2.0 s when the caller cuts in, then answers the new question.
✓ Emergency routing
Sends a knocked-out-tooth caller to immediate care, even when they push for a routine slot.
✓ Reply speed
Median reply gap and p90, measured over the phone line.
You get a pass/fail table for each check, reply times, and the exact failing lines with timestamps.

FAQ
Is it HIPAA compliant? Will there be a BAA?
Your agent runs on your own account with the platform you choose, so the BAA is between your practice and that platform. Not every voice-agent platform offers one; during the shortlist we only recommend options whose BAA terms fit your needs, and we tell you plainly which ones do. Our test calls use fictional patient data.
Does it work with my booking software?
It depends on your practice-management and booking software and on the agent platform. We check this in the audit before you pay for setup. Where a direct booking integration isn’t available, the agent can take a request and hand it to your team instead.
Will patients know they’re talking to an AI?
We set the agent up to say it’s an AI assistant at the start of the call, and to transfer to a person or take a message when asked.
Conflict-of-interest disclosure
- Paid setup work never affects our benchmark results or rankings.
- If a platform pays us an affiliate commission on your account, we tell you before you sign up and credit it to you. See how Cozzo makes money.
