I can make calls no issues, I also receive calls except when my grandfather and sister try from their landlines it has either a busy signal or it says “All circuits are busy" I am able to phone them though. I checked block list, they are not on it. They were able to call me fine yesterday.
An all-circuits-busy message or a fast-busy tone means that there aren’t any free outgoing lines. It happens occasionally that more people call than there are available phone lines. Simply hang up and try again. A phone line should free up shortly.This message can indicate a service outage such as a cut cable or equipment that’s been damaged by weather.If you continue to get this message, note when the problem began happening and/or what time of day it happens most frequently, and contact to your carrier or landline phone company
