Available time slots

Available time slots indicate when appointments are generally possible. From these time slots the Nexcal Calendar, together with the meeting duration and the booking window, calculates the concrete slots the AI voice agent may offer during the conversation.

Without released time slots, no slots are created and the agent cannot offer an appointment. Maintaining the time slots is therefore a central part of a working appointment booking.

From time slots to bookable slots

A time slot describes a permitted period, for example on certain weekdays and times. From this, individual bookable slots are formed:

  • The meeting duration divides the time slot into individual appointments.
  • The booking window limits which of these slots are actually offered.
  • Appointments that are already booked are held back and not offered again.

Every offered slot therefore stays tied to your configuration and the current booking status.

Maintaining time slots sensibly

  1. Define the periods in which appointments can actually take place.
  2. Make sure the time slots match the meeting duration.
  3. Take into account the lead time defined in the booking window.
  4. Check regularly whether the time slots are still current.

The interaction with further settings is described in the articles meeting duration and booking window.

Hinweis: If the agent offers no appointment, it is often due to missing or too narrow time slots. In that case, check the released times as well as the meeting duration and booking window.

Time slots and double bookings

The Nexcal Calendar takes appointments that are already taken into account so that the same time is not offered twice. How double bookings can be avoided is described in the article avoiding double bookings.
