Making 911 calls over VPN

We've had a few questions about this, so I want to clarify. 

When a 911 call is placed from a remote phone over a VPN using Response Point, the following sequence occurs:

1. A recorded message is played: “Unable to determine your current address. Please provide your address to the emergency services operator. Alternatively, hang up and use a land line or mobile phone to make this call to emergency services.” The reason for the warning is that the caller’s location may not be the same as the location registered with the company’s phone service.

2. If the user stays on the line, the system then places their 911 call.
