The continuation of the task is analogous to the one presented earlier. Unless... the employee answers the phone.
This is one of the situations where an employee has to interrupt a task for reasons unrelated to the task at hand.

For what purpose is data on interruptions useful? Some managers need it to analyze the factors that negatively affect employee focus, so, thanks to that they can eliminate them.
