I Put 6 AI Phone Agents on Hold at a Real Dentist: All Book, Retell Sounds Best
Evening_Hawk_7470 · reddit · 2026-10-01
A second-round field test put 6 AI phone agents through the same task—booking a kid's dentist checkup as an AI, mid-call hold included. Retell had the best voice and speed but needs ID verification and number purchase; PlaceCall came second with zero-setup real phone lines; ClawCall handled holds best; AgentPhone improved over last week. Practical tips: put the current date/time in the brief and avoid saying "Pacific"—one agent repeated it to the receptionist. Booking success no longer differentiates products; hold behavior, voice quality, and setup friction do.
