Answer:
Answering machine
Step-by-step explanation:
Answering machine is a form of telephoning system that is designed to automatically answer and record telephone calls even when a receiver is not around to do so.With this feature , it allows flexibility as the user can still attend to other functions without loosing track of the the calls for the day.
Even though it has a weakness in that calls that require immediate responses may not get such , however , those calls can be responded to as soon as the users get to know about it , hence the need for frequent check of the call logs by the user.
Looking at this definition , it it suits the need of a regular health worker that need to check in either at regular intervals while the agency is closed or on the next business day.
