Our take

Editorial opinion, reviewed 16 October 2026.

A good fit for
Developers and agencies building voice agents who want per-minute pricing broken down by component.
Look elsewhere if
You want a finished receptionist service rather than a platform to build one.
On pricing
Calls cost $0.07 to $0.31 a minute depending on the model and voice; phone numbers are $2 a month each.
