I realize every new outlet on the internet is regurgitating this story but if I call you via whats app and are both using wifi does the communication even transit an SS7 gateway at all? Why would it? Also SS7 is generally a closed system, not anyone can connect to an SS7 gateway. To signal to a carrier&#x27;s SS7 gateway you have to either be a subscriber or carrier that has agreement with the owner of a SS7 gateway to terminate traffic, since this is how calls are billed. For an external carrier to connect to another carriers SS7 gateway they need to know your &quot;code points&quot;(kind of like an IP address for SS7.) in advance. There wasn&#x27;t a lot to go on in the google translated doc.
