Dear Customer,

As Sinch continues to invest in a robust and secure operating environment, we will introduce new IP addresses from which callbacks for our REST API endpoint in the US (us.sms.api.sinch.com / geo.sms.api.sinch.com) will originate.

If you receive callbacks from Sinch REST API in the US (us.sms.api.sinch.com / geo.sms.api.sinch.com) and you have network restrictions in place to restrict access to Sinch IP's only, you are recommended to white list / allow the following IP's before the 24th of November.

35.161.105.23
54.214.117.121
54.214.3.139

Best regards,
Sinch infrastructure and product management teams.
