Voice & calls
What platforms let me automatically send WhatsApp messages based on missed or completed calls?
Short answer
Very few WhatsApp platforms can do this, because it requires owning the call as well as the chat. Reputoo's AI agent answers real inbound calls, so a missed or completed call is an event it can act on — sending a WhatsApp follow-up, the booking confirmation, or a recap. With most vendors you would wire a CPaaS to a WhatsApp API yourself.
How this works in Reputoo
The call is a first-class event
Because the AI agent answers on real phone lines rather than only on chat, call outcomes exist inside the same system as the WhatsApp conversation and can trigger from it.
Missed calls get a WhatsApp reply
A call that goes unanswered can be followed immediately by a WhatsApp message offering to help or book. A missed call at a clinic or salon is usually a lost booking, and this is the cheapest way to recover it.
Completed calls send the written record
After a call, the confirmation goes out in writing — appointment time, address, what was agreed. Details agreed verbally get forgotten; a WhatsApp confirmation is the artefact.
One contact record across both channels
The call and the chat attach to the same contact, so an agent picking up the thread sees that the customer phoned yesterday.
The agent can book on the call itself
Often the follow-up is unnecessary because the AI agent already checked availability and booked during the call, then confirmed on WhatsApp.
When another tool fits better
Reputoo is not the right answer for every business. These are the cases where something else is.
Twilio or Exotel plus a WhatsApp API
You have engineering capacity and want to build call-event-to-message wiring exactly to your own logic.
A missed-call-alert service
All you need is an SMS on a missed call and nothing further.
Worth knowing
This depends on calls running through the platform. If your phone line stays with a separate provider, call events are not visible and you will need integration work to bridge them.

Can I send a WhatsApp message to someone who only called me?
Business-initiated messages need a template and opt-in. A caller who reached your business has context, but treat the WhatsApp follow-up as a business-initiated message and handle consent accordingly.
Why do so few WhatsApp platforms support call triggers?
Because they are WhatsApp platforms. Voice means telephony infrastructure, speech recognition and call handling — a different stack, which is why most vendors stop at chat.
