Last week our DND function on our IP Phones stopped working. For some reason the softkey doesn't work. When I press it, nothing happens. There are 2 phones stuck in dnd mode and I can't seem to get them off dnd.
Anyone got an idea how to fix this? I've been looking all over cisco.com and the Internet, but I can't find anything about solving this issue.
Thanks in advance.
ps: If you need more information about the config I have, just ask me.
