Appointment reminder call with a WhatsApp fallback: what happens when nobody answers
How an appointment reminder call from a voice agent works when nobody answers or voicemail picks up: the reminder continues automatically on WhatsApp.
The problem with the call nobody answers
A reminder call works when someone picks up: they confirm, reschedule or cancel on the spot. When nobody answers, the reminder is lost, and a manual retry keeps the front desk busy. The WhatsApp fallback covers exactly that case.
How Wenzy chains it
- 1Call before the appointmentThe voice agent calls to remind the customer, within the business's contact hours and never after the appointment time.
- 2If they answerThey confirm, reschedule on the same call from free calendar slots, or cancel; everything lands in the customer's conversation.
- 3If voicemail picks upThe agent leaves the business message and then sends an AI-written WhatsApp.
- 4If nobody answersThe reminder continues on WhatsApp, in the customer's same conversation.
- 5RetriesConfigurable, and cancelled if the person writes first.
What your team sees
- Each call attempt with its outcome: answered, voicemail or no answer.
- Recording, summary and transcript of answered calls.
- The fallback WhatsApp and the customer's reply, in the same thread.
