I've been having some issues getting my voice mail to work on the Captivate. Every time callers tries to leave a VM they get a message saying that I'm not available right now and to try back later. Never gives an option even to leave a VM. I'm not sure if it's a the phone or if it's AT&T issue. I tried setting up the VM with both my carrier and Google Voice, but no luck. Anyone else having or had this issue?
