A missed call often happens for a perfectly reasonable reason: the team is on a job, speaking with another customer, or unavailable after hours. The customer, however, may still move on to the next business that responds.
Missed-call text-back creates an immediate second chance. When a call is not answered, the customer receives a short message acknowledging the call and inviting them to share what they need.
From there, the workflow can collect basic information, ask a qualifying question, or direct the customer toward a booking step.
