I'm not sure when it started but, I know PB/SBC/ATT in CA. offered me SS7 connectivity many years ago. I'm pretty sure all of the Baby Bells now offer the service. I am sure SNET does as well. Now the choice is up to you if you want them to see all of your PSTN-bound traffic. The technology still holds true that your SS7 provider is all or nothing.

There was a time that you could not buy commercial access to the SS7 network; to get that access you had to be a real carrier. Also, back at that time, inter-company SS7 signalling could only occur on established, ordered signaling routes where both parties placed an order to open the route between them. Therefore, this would not have been possible back then because the carrier would not have ordered a route to the hacker’s point code(s) and it therefore would not exist.<u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1f497d"><u></u> <u></u></span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1f497d">If I am a US local carrier in 2001, I have no need to order a signaling route to a German carrier either so even the hacker having full access to a German carrier’s network would not compromise my network.

At some point, a decision was made somewhere to allow this loosy-goosy inter-company signaling over the SS7 network between two point codes that would not, under the original implementation of SS7, be able to talk to each other in the first place.<u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1f497d"><u></u> <u></u></span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1f497d">If the drumbeat of “solve everything with IP!” continues, I hope that at least it gets solved by establishing something close to what the VPF was supposed to be, and not just a general dumping of all voice traffic across the internet between carriers.
