One of our exec staff wants to have his phone ring at his own Exec phone and also ring at the secretary's (one of the undefined key). The secretary needs to hear the ring and has the option to pick it up and answer it or just let it ring and it goes into the exec staff's own voice message box. I have setup one up about a year ago and I can't remember now how I got this done.
Where do I start? or someone got an easy to follow instruction sheet to share?
