Since VoIP services can be used from any internet-connected device, there is an assumption that it cannot be associated with a specific physical address. Which would then mean an emergency call would not be routed appropriately.
Not true. Enhanced 911 (E911) service solves that problem.
With E911, we associate a physical address with the caller’s telephone number and route calls to the most appropriate Public Safety Answering Point (PSAP) for that address.
In the case of a cell phone user, the phone number and receiving antenna are sent to a dedicated switch for E911 calls. This will route the call to the appropriate PSAP, and then an operator can see the approximate location based on GPS triangulation.
