When I listen to my visual voicemail through my headphones, I can make it through only one message. Immediately following that first message, the volume drops to almost nothing through my headphones, making it impossible to hear (or even difficult to tell if it's outputting any sound at all). This also affects when I listen to all my voicemail messages in my car, as I play through my tape deck with a line out adapter.
The only way to restore sound to the headphones is to restart the phone, which is cumbersome and loud.
