Definitely not the case with VOIP. I had a case where a roommate in college had to call 911 on our VOIP phone (bad cell service in the house) and we were connected to a dispatcher in a different state (where I had lived previously). I doubt if most people remember to update their location with the VOIP provider when they move.

Does this apply to VOIP? A lot of POTS phones here in Norway are plugged into the network router not a physical landline.
