Voice AI platforms for agencies building receptionists
Included: Tools the vendor positions as a voice AI platform you configure or build on.
Order: Lowest published monthly plan first; usage-only pricing last.
Data: each vendor's own pricing page, check date per row. Nobody paid to be on this list. Methodology
These aren't plug-and-play receptionists. You (or an agency) design the agent, connect a phone number, and pay usage, often per minute plus model and telephony costs.
For a contractor who wants something working this week, a standalone AI receptionist is usually the better buy. Agencies serving many shops are the audience here.
