Using the state-based approach to modeling, as discussed in section 21.1.1, model the operation of an embedded software system for a voicemail system included in a landline phone. This should display the number of recorded messages on an LED display and should allow the user to dial-in and listen to the recorded messages.
What will be an ideal response?
There are many possible solutions to this question depending on how detailed a
model is produced. The diagram shows one possible state model. Notice this does
not allow for message deletion (as this was not asked for in the question). Adding
deletion after playback is simple with an additional state that deletes the message
and reduces the message count.
