Calls Going Straight to Voicemail

For the past two weeks I have been having issues with my phone where any calls that I received went straight to voicemail. So, after reading online from others who also had the same problems, I saw one comment where someone mentioned checking your settings on your Mac book and turning off the "Do Not Disturb" button, and sure enough, that was the issue. For anyone who is having that issue, my suggestion would be to check the settings on your Macbook, I hope this helps anyone out.
