Reproduce the calculation
Minute plans: monthly subscription + max(0, billable minutes − included minutes) × extra-minute rate + phone and other required charges.
Call plans: monthly subscription + max(0, billable calls − included calls) × extra-call rate. A unique-customer plan substitutes distinct customers for calls.
For Vocapable, AI time includes listening, silence and tool waits. Apply the 30-second minimum to each AI-handled call before adding the month. We choose the lowest modeled paid tier, and include Free only when all stated call, minute and per-call limits fit. We do not assume the user upgrades automatically.
For Smith.ai, we compare ordinary-call Free overage against applicable paid tiers; chargeable advanced actions are excluded. For Upfirst and Goodcall, we choose the lowest published tier-plus-overage total. Rosie figures are tiers that cover the minutes because overage pricing was not verified. RingCentral figures use its published standalone overage; bundles may reduce the price. Dialzara totals above its verified entry allowance need a quote.
My AI Front Desk examples assume its monthly shared 1,000-credit pool is used only for voice beyond 200 minutes. We then count complete $10 reload blocks, rather than presenting a fraction of a block as the amount charged. Other activity using the shared pool changes the result.
No annual discount, introductory credit, negotiated price, acquisition cost or unverified productivity saving is included. The table covers eight selected competitors. Phonely’s free allowance is clear, but its paid cards and detailed table disagree; higher-volume prices remain unquoted.
