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 Redhot XML, SMS, SDI and HTTP API in the US for the following FQDNs:

ssl-xml.us.mblox.com
us.sms.sdi.sinch.com
us.span.api.sinch.com
us.xml.api.sinch.com
us1.span.api.sinch.com
us2.span.api.sinch.com
venice.api.sinch.com
xml.us.mblox.com
xml.us.mblox.com.com
xml001.nj2.us.mblox.com
xml001.qsv.us.mblox.com
xml001.us.mblox.com
xml001.us1.us.mblox.com
xml2.us.mblox.com
xml3.us.mblox.com
xml4.us.mblox.com
xml5.us.mblox.com
xml6.us.mblox.com
xml7.us.mblox.com

If you receive callbacks from the above mentioned APIs in the US 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 as soon as possible

35.161.105.23
54.214.117.121
54.214.3.139

Best regards,
Sinch infrastructure and product management teams.
