Can I set all the phones in the office to DND without having to do it individually?

Hello @user_08cfd9 Thanks so much for reaching out to our team for help with your do not disturb questions. Currently, we do not have a way to place all lines on do not disturb at once. This is a great question and I will share your feedback as this will save time. 

I have a link with the steps on how to turn on our calling features including do not disturb. https://business.comcast.com/support/article/voice/phone-using-call-management-features

Did you have anymore questions for us today?
