It's a cheaper way to go initially for those who don't deliver tons of traffic to the PSTN. Right now it is only available in Verizon territories as far as I know, but as soon as the process for the new Interconnected VOIP carriers is established, you should be able to do it in any major ILEC/RBOC area. Just a thought for those who don't want to put all the money into becoming a full-fledged facilities-based CLEC.</div>

All of the same info rides the SigTran deployment as an SS7 A/E/F-Link, plus possibly more.... depending on what type of messaging you're talking about. However, it also lacks voice content, like the SS7 network.<br><br></div>

<div dir="ltr">I haven't used SS7 in the voice world, only touched briefly on the messaging side of it. Would hackers be able to do the same similar attack via SIGTRAN? I would think it would be easier to get access to a poorly managed SIGTRAN device which would then give you SS7 access.

<div>Or even an Asterisk box running SS7 trunks.</div>

<div>I noticed that in Gmail (and perhaps other email systems), the longer reply I wrote for Kidd was hidden because it appeared after his text. Here's what I wrote...</div>

<div>
<div>what's fascinating is the recent rise in end-to-end (e2e) encryption among IP-based communications platforms that include voice.</div>
<div> </div>
<div>WhatsApp, for instance, just completed the rollout of e2e encryption on April 5, and not just for messaging, but also for voice and video calls as well as file transfers ( <a href="https://blog.whatsapp.com/10000618/end-to-end-encryption" target="_blank">https://blog.whatsapp.com/10000618/end-to-end-encryption</a> ). Just yesterday the team behind Viber announced that they will soon have e2e encryption for all clients. The app Wire ( <a href="http://wire.com" target="_blank">http://wire.com</a> ) also does e2e encryption for voice, video and group chats.</div>
<div> </div>
<div>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. (You can view the exchange via the link in this tweet: <a href="https://twitter.com/csoghoian/status/722854012567969794" target="_blank">https://twitter.com/csoghoian/status/722854012567969794</a> )</div>
<div> </div>
<div>The end result is that we're definitely moving to a space where the communication over IP-based solutions will wind up being far more secure than what we had before.</div>
<div> </div>
<div>Interesting times,</div>
