What are the disadvantages of a telephone message?

Disadvantages:

1. Messages can often be interpreted wrongly when there is no one to correct the confusion.

2. You cannot ask the person questions like you would having a conversation with them and this can waste time, two people leaving replying to messages all day, as one of them is always busy while the other is not.

3. Other people can listen to your messages when some of them might be private.

4. If somebody is trying to reach you in an emergency situation and you have voicemail switched on, then you will not know that something bad has happened until maybe too late.

I'm actually doing part of an assignment on this subject right now, that's all I have come up with so far. Hope it helped!
