Source note · Setting up dynamic emergency calling in Microsoft Teams

On an emergency call with a dynamic location, the SBC ELIN application matches the location to an ELIN record, substitutes the caller's number with the ELIN number and routes to the serving PSAP; on a call-back to the ELIN it reverses the substitution to reach the original caller.
