What Kallix and Cal.com do together.

Booking events start calls
Cal.com webhooks for new, rescheduled and cancelled bookings can add the attendee to a Kallix campaign, with the booking time as a variable.
Confirmation calls
Call attendees ahead of the booking to confirm, and record who will come and who needs a new time.
Cancellations followed up
When someone cancels, the agent calls to ask why and captures the time that would suit them instead.
Bookings by API
Developers can take the time a caller agreed and create the booking through Cal.com's API after the call.
