I agree. Almost all talk too quietly or shout, and pretty much all are incoherent for the person on the other end.
I hate the answer phone messages done my children!
I never let my DD answer the phone, even now she is a bit older. When I was little we had some vile vile calls that I was subejcted too, simply as I was the one who answered them. Very disturbing and very scary - I won't risk it. DD simply knows she isn't to do it. Also, it might be a professional call - something to do with work, or DH's clients, or the bank, etc.
