So this is a really odd report... Multiple users of one of our systems report that they are unable to cancel DND status for their phone (which they set via a star code, not the phone's own DND button). When they go to cancel the DND status, it seems to stick for about 10 seconds, then Asterisk self-reverts the extension to a DND status. The problem seems to be cleared by power cycling the extension--though why this is related, I am at a complete loss. Any ideas?
