ZoomPhone Emergency Address

As an internet business with staff that are always out in the field and travelling I find it pointless that you require an emergency home address. Surely if an emergency had to occur and you sent out first responders to this address but the person was not even there, this would be a bigger issue than say listing the fact the person travels extensively and their location changes everyday?  

I can understand this for a service aimed at a home user but not a business. Just as an aside other vendors do not require this!
