Connected carefully

Provider-neutral where it matters.

Infrastructure integrations stay behind Frontal Voice contracts so customer workflows do not depend on one vendor's data model.

Voice provider

Natural AI voices run on dedicated voice infrastructure behind a Frontal Voice contract, so your receptionist is not locked to one vendor.

Calendars

Google Calendar and Cal.com adapters sit beside a deterministic mock calendar.

Notifications

Email and SMS channels use replaceable provider abstractions and never claim delivery before confirmation.

Outbound webhooks

Growth and Professional organizations can deliver normalized lead and appointment events to customer systems.

Billing

Stripe Checkout, portal, subscriptions, and metered usage are isolated behind a high-integrity billing subsystem.
