I apologize if this had already been answered in another thread but I could not find it.... But does anybody know why you can only hear voicemails over the speakerphone on the visual voicemail application with AT&T? I find that rather odd and don't know if it is a bug or normal functionality. The AT&T rep did not know if it was a bug or not and seemed confused himself and he owns a Lumia 920 as well. Any help or comments are appreciated!
