This amount covers the entered voice, AI and fax requirements, with comparable exclusions.

Understand the estimate.

Competitor plans can include different applications, messaging, integrations, support and allowances. This compares modeled costs, not feature equivalence. Taxes, applicable fees, equipment, setup and unpriced services are outside the estimate unless shown. AI call-based estimates depend on the displayed duration and qualifying-call assumptions. Annual figures assume unchanged prices and repeated monthly usage, not guaranteed invoices. Actual quotations may differ.

Every card shows approximate savings for the services identified beside its savings box. When a full AI or fax configuration cannot be verified, those services are left out on both sides: the comparison uses phone-only or phone-and-AI costs, not an invented rival total. Aircall uses its annual-rate reference; the box identifies the available Zephyr Voice plan and its actual commitment. A reduced number allowance is identified when extra-number pricing is unknown. Stale provider cards are hidden until refreshed. No information entered here is sent to a server or saved.
