Our entire office is experiencing problems since yesterday. Our phone lines show active and available, and we are able to place and receive calls however the person on the other end of the line cannot hear us. At first this was an issue with only our base phones and the computer app and phone app continued functioning properly. Today not only do our base phones not work but our computer and phone apps are not working for a vast majority of employees. Anyone have any issues like this? Our IT department has determined it is not a problem with our servers or internal hardware.
