Whenever anyone calls my voicemail, including myself, it rings a couple of times then says "Welcome to Verizon wireless. Your call cannot be completed as dialed. please check your number then dial again. Announcement 4 switch 179-4. " It says it twice then hangs up. It's been doing this for a couple of months. I just got an env touch and it still does this. I've changed my voicemail number from *86 to my number and it hasn't helped. Is there anything else I can try?
