 ## Important considerations
 - The capability to dial an emergency number and receive a call-back may be a requirement for your application. Verify the emergency calling requirements with your legal counsel. 
 - Microsoft uses country codes according to ISO 3166-1 alpha-2 standard 
-- If the country ISO code is not provided to the SDK, the IP address will be used to determine the country of the caller. 
-- In case IP address cannot provide reliable geolocation, for example the user is on a Virtual Private Network, it is required to set the ISO Code of the calling country using the API in the Azure Communication Services Calling SDK. 
-- If users are dialing from a US territory (for example Guam, US Virgin Islands, Northern Marianas, or American Samoa), it is required to set the ISO code to the US

 - Azure Communication Services direct routing is currently in public preview and not intended for production workloads. So emergency dialing is out of scope for Azure Communication Services direct routing.
