Voicemail/Phone not working properly

I tried accessing my voicemail from my wireless home phone yesterday and when prompted to press ‘1’ to check the new voicemails, it wouldn’t do anything. Then I would hang up the phone and try again and the voicemail menu would still be running. Today, the voicemail menu is still running when I hit the ‘talk’ button on the phone and I can’t even make a call out.
