I have all of my SCCP phones configured for a company wide paging group. We have noticed that on some phones, like a phone in the conference room and the phones in the executive offices, we would like to be able to at times have the user turn off paging. I thought the DND would do it but it doesn't. Is there a way to do this? If it can't be done with the DND, I guess we could just have the user turn the ringer volume all the way down but the users just want to be able to hit one button, like DND! Any ideas? Maybe a softkey for mute?
