If you have an iPhone you may need to unblock our phone number by:
In Settings go to Phone > Call Blocking and Identification, where a list of blocked contacts and numbers will appear. Tap Edit in the top right-hand corner. Then tap the red delete button to the left of the number 405-308-4474, which will cause a red unblock button to appear. Select it, and the contact is restored to unblocked.
Once the number has been unblocked you should then be able to receive your phone call.
