I am new to the Droid and Verizon and have signed up for visual voicemail. The problem is that when I receive one I can barely hear it. I have the volume all the way up, but no luck.
Not to state the obvious, but there are 2 audio output options in VVM. You can set it to play thrugh the speakerphone speaker or the regular speaker. Make sure you're setting it to the right one based on your listening choice. Personally I did not have this issue with VVM, but I was having several others, I switched to YouMail and ultimately PhoneFusion Voicemail. PF works much better for me.
