<div>1. They don't usually offer SigTran so in addition to the SS7 ports, you also have to pay for the transport to the STPs.</div>
<div>2. They will usually only cover routes in their territory so if you go into another LEC territory they will tell you that you need a second set of links for those areas. Companies like Syniverse and Neustar are connected to pretty much everyone and while some routes are off-net and cost more, they will only require one set of SS7 links.</div>

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. You can't have multiple SS7 providers yet.<br><br></div>

<p class="MsoNormal"><span style="font-size: 11.0pt; font-family: 'Calibri',sans-serif; color: #1f497d;">It seems to me that this SS7 vulnerability issue is just the latest result of all of the de-regulation that’s been going on for the past… two decades or so. 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.<span style="text-decoration: underline;"></span><span style="text-decoration: underline;"></span></span></p>
<p class="MsoNormal"><span style="font-size: 11.0pt; font-family: 'Calibri',sans-serif; color: #1f497d;"><span style="text-decoration: underline;"></span> <span style="text-decoration: underline;"></span></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. (in response to the nation-state issue) To get a call to Germany, I signal to the access tandem or IXC switch I’ve chosen to interconnect with in the US and that switch signals upstream, etc.<span style="text-decoration: underline;"></span><span style="text-decoration: underline;"></span></span></p>
<p class="MsoNormal"><span style="font-size: 11.0pt; font-family: 'Calibri',sans-serif; color: #1f497d;"><span style="text-decoration: underline;"></span> <span style="text-decoration: underline;"></span></span></p>
<p class="MsoNormal"><span style="font-size: 11.0pt; font-family: 'Calibri',sans-serif; color: #1f497d;">If we were not on this path of de-regulation where whatever makes commercial sense for one company can open up the whole SS7 network to un-trusted parties, we likely wouldn’t be here. 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.<span style="text-decoration: underline;"></span><span style="text-decoration: underline;"></span></span></p>
<p class="MsoNormal"><span style="font-size: 11.0pt; font-family: 'Calibri',sans-serif; color: #1f497d;"><span style="text-decoration: underline;"></span> <span style="text-decoration: underline;"></span></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. That certainly wouldn’t bode well for reliability or security.<span style="text-decoration: underline;"></span><span style="text-decoration: underline;"></span></span></p>

<p class="MsoNormal">In a US Congress hearing this week, a Congressman asked a Dept of Homeland Security representative if e2e encryption available in apps would have prevented this interception that happened via SS7. The DHS answer was that it would mitigate the interception of the content, although the location meta-data would still be available.
