OK, here's another seemingly easy one....how do I build a multi-appearance phone that allows all parties to hear each other? I have 4 x 2616's phones that have a number built on them. There was also an analog phone that had this number, which they wanted swapped out for a digital. I outed that and built a 3904 to replace it with. For whatever reason if another phone picks up that line they can not hear/talk on it? (This is an internal emergency line) is there a cls that needs changed...?
