Description:
Sinch is upgrading its platforms and optimizing its servers for TWW Customers.

As a part of this we require all TWW HTTP Customers that are currently using the URLs starting with https://webservices.twwwireless.com.br to whitelist below IPs from SINCH. This needs to be done prior to September 20th, 2023.

Datacenter IP Address
BR 1 18.228.91.50
18.230.36.163

BR 2 20.197.230.169
20.201.124.17
20.197.230.169
20.195.165.164

Action required:
If IPs are not whitelisted, customers will still be able to send MTs but not receive any MT DRs and MOs on HTTP Accounts.
