Using API to initiate 911 call

I'm building an application where an operator may need to place a 911 call on behalf of someone at a location that:

  • Is different from where the operator is physically located
  • Changes dynamically at runtime (i.e. it is not known in advance)

I understand that E911 is designed to address dispatchable location requirements for VoIP calls, but I'm struggling to find a clear, reliable API approach for this scenario.

 

My key concern is timing: even if I update the registered E911 location via API immediately before the call is placed, I cannot guarantee that the updated location will be propagated to the PSAP before the call is answered.

 

Can you please point me to the best practice and API set to use in this scenario ? thank you in advance.

Unfortunately, there is no other way to pass an address to an emergency call.

If the emergency locations have been registered successfully, changing the emergency location for a device would be very fast (less than a sec) and the workaround solution should work in that case.
