Having an issue with an executive zero out option that was set up. If you dial any one of the administration numbers, it is set up to zero out to 6212, which points to coverage path 9, which inside has c1 as the first option, attd as the second option. When I dial any one of the extensions and hit zero, it states "invalid extension". Nothing was changed, so i'm a little puzzled at why all of a sudden this is happening. We're on a Definity G3si, CM 1.2. Any help is greatly appreciated. Thanks.
