The threat to operators’ A2P revenues from messaging service providers utilising grey routes and least cost routing is well documented, and awareness of the issue is growing in the industry. Many MNOs have responded to this by putting in place filtering systems to control inbound SMS traffic from SS7 and international routes, the traditional source of grey route traffic. However, with international routes more commonly becoming blocked, an increasingly diverse set of new low cost routes have started to become exploited.
In this whitepaper, HAUD discusses the importance of controlling all access points to a network, and not just international messaging gateways. By taking this approach to effectively ring-fence their network, MNOs can take control of each entry point to their network, and level the playing field for both themselves and aggregators to create fairer market conditions.
