As the latest unfortunate VoIP 9/11 call mishap teaches us, it is important to ensure we read the fine print. Quite often we quickly hit the 'I agree' button presented just below the heap of tiny legalize in front of us. Listed in there, I'm sure, it would state that it is the users responsibility to notify the company of any relocation, so that in the event of a 911 call, they can transfer the call correctly. Which may sound good at the time, but if you are like most of us, putting off updating small details like account information can be easily forgotten, wedged in the bottom of the never ending to-do-pile. Since we can still use the service, there is nothing prompting us to 'get it done'. If you follow the letter of the End User Agreement (EAU), then the fault lies on you the consumer, if you fail to update your current information. But I believe there should be some responsibility with the company. Simply referencing the address in the database is the lazy way out. There is no fail safe to ensure it's accuracy other than the EUA.Which means it's all up to you, the user.
