Look, the whole point here is the difference between ringing the SAME DID at multiple locations (which I do not think is possible) and ringing multiple numbers are various locations (which everything in the world can do) The reason that one cannot have the SAME DID attached to multiple devices is that the unique DID is used for ROUTING, and E911 and PORTING and BILLING. If I could have the SAME DID ACTUALLY on multiple devices how could E911 work? It couldn't. It wouldn't know where each device was actually, or from where the 911 call was coming. Now, of course I can move ANY device but the point is that ONE device gets ONE DID at ONE TIME.
