Voice Mail

Hi everyone, I'm new to using a Droid phone. I currently have a LG Ally and trying it out. Is there a way to delete voice mails without opening them? Sometimes there is a need to not open them but I can't figure out how to get them off my notifications without opening and listening to them. On my other phone I was able to go in to see who called and delete it without opening it. Thanks guys for any help.
