1 I'm too busy with other work.

There are too many telephones, and the staff are annoyed.

There are too many phone calls with similar problems, which annoys the staff.

Some problems will be exposed at that time, and it is difficult for the staff to be sure at the moment.

. . . . . .

Of course, as a responsible admissions office, you should arrange someone to answer the phone and answer candidates' questions.

(Public schools don't worry about finding students, so most of them have them. If it is a private school, most of the calls can be made, and the people who answer the phone are also very enthusiastic)
