You would like to set up a configuration for the Firewall Advanced Filters (FAF) to block SMS dispatch to international numbers, but when checking the 'Recipient TON=unknown' option you notice you are also blocking short numbers that were not supposed to be blocked.
Please raise a support request to the NewNet Support Team sharing your current FAF configuration and describing what you are trying to achieve. An agent will guide you to ensure you have the optimal configuration setup.
For general information about FAF configuration, refer to the 'NewNet Mobile Messaging SMS Firewall User Guide' found in the NewNet Download Center.
<supportagent>Agents only: optimal configuration solutions are in the scope of the Professional Services team. Please follow the process described in BU Escalation Process to resolve the issue.
