The question came early and often during our participation at Astricon 2018 in Orlando. “What’s the difference between an SBC and a SIP Server like Kamailio or OpenSIPs?” Reminding us that in our world of telecom jargon, sometimes we need to stop and explain what we are talking about.

As a greater range of communications applications are migrating to the cloud, there is a greater need for affordable cloud-hosted session border controller network services. To answer this need, TelcoBridges recently announced that the company’s FreeSBC session border controller software is now available on Amazon Web Services. Offering feature-rich services comparable to native bare-metal installations and virtualized platforms, the AWS Amazon Machine Image (AMI), provides core network security, interoperability and media services for service providers and enterprises.
Across the industry, cloud-based communications is on a steady growth trend. As application architects piece together their solutions using cloud-bases services, it makes sense to have an affordable SBC to provide security, interoperability and media services.
Greg Collins at Exact Ventures forecasts that by 2022 nearly 75% of all session border controller shipments will be cloud-based
Luc Morissette, Director of Customer Support at TelcoBridges will be joining me for a live webinar on Tuesday, September 25th to deliver an overview of the new FreeSBC on AWS offer, covering the capabilities, limitations and demonstrating the activation process.
During the webinar we explain the three distinct offerings, including:
The session will wrap up by putting a spotlight on the many use cases, showing how hosted contact centers, hosted Unified Communications and traditional telephony services will benefit from cloud-based FreeSBC.

The battle to tame fraudulent robocalling made some significant advancements this week as the SIP Forum released two new technical reports.
If you’ve been following along, you know that fraudulent robocalling and caller-ID spoofing have become the tools-of-the-trade for criminals trying to trick unsuspecting victims into their scams. (By now you’ve come to realize that you can’t trust the caller-ID on your phone.) The FCC and the CRTC have put deadlines in front of the carriers, requiring implementation of secure caller-ID technologies to prevent spoofing of caller-ID.
To address these requirements, the ATIS and SIP Forum announced this week the release of two key specifications needed to standardize the user experience and APIs needed for implementation of SHAKEN.
The first specification Technical Report on a Framework for Display of Verified Caller ID (ATIS-1000081) defines a standard user experience for calls from known callers, likely SPAM callers, suspect and potential fraudulent callers with color icons and information on screen-based devices. The specification details the user experience study that went into the graphical images, providing data on real-world user responses and behaviors to the information displayed.
The second specification Technical Report on SHAKEN API for a Centralized Signing and Signature Validation Server provides a proposed RESTful API for the implementation of the SHAKEN specification, used to authenticate and verify caller-ID for network-based calls. This recommendation is an alternative to the SIP-based mechanism as specified in the SHAKEN recommendations, as is currently used by a number of vendors, including TransNexus and TelcoBridges.
“These two new resources are critical to helping service providers implement SHAKEN,” said ATIS President and CEO Susan Miller. “They are products of ATIS’ continued collaboration with the SIP Forum and are instrumental to industry efforts to address the robocalling problem and maintain consumer trust in the voice network.”
“The SIP Forum is committed to working together with ATIS to continue to develop the operational documents for the SHAKEN Framework, and these two new reports provide important additional guidelines and details essential to the successful deployment of the SHAKEN standard,” said SIP Forum Chairman Richard Shockey.
In addition to the above announcement, we’ve made significant progress with TransNexus on their SHAKEN fraud prevention framework, recently posted detailed configuration notes on how to configure both FreeSBC and TransNexus OSPrey server and completed our bench testing milestones.
Looking ahead and demonstrating the level of interest on the topic, a dedicated track and session on Robocalling is scheduled for SIPNOC 2018.

Last week we hosted a webinar with our Alliance Partner TransNexus, titled “Battling Robocaller Fraud – an Introduction to STIR/SHAKEN”. As we expected, the topic was wildly popular with a larger than normal audience attending the live event and a long list of great questions during the Q/A.
As noted by Jim Dalton, CEO of TransNexus at the start of the session, automatic dialers with pre-programmed IVR scripts (aka Robocallers) do have valid applications (reminder calls from medical offices, bill pay reminders, school closures, reverse 911…) But they are increasingly being used as part of elaborate fraud schemes, bilking victims and stealing their identities. As noted by the Treasury Inspector General for Tax Administration (TIGTA), over 10,000 victims have collectively paid over $54 million because of phone scams since October 2013. And that’s just the crime that was reported.
What is STIR/SHAKEN?
In a nut-shell, STIR/SHAKEN is a framework that adds an encrypted identity certificate to the header of a SIP INVITE (the message that initiates the call), proving that the originator has permission to use the associated caller-ID.
Once the call makes its way through the various IP-based wholesale operators, the terminating operator can use a public key to examine the certificate and verify that the caller-ID is intact and rightfully being used by the originator. Calls with a valid certificate will pass to the recipient unimpeded and with the associated caller-ID, knowing it is valid. If a call arrives without a valid certificate, the terminating operator may flag the call as possible SPAM, send the call to a Captcha-like screening application or block the call altogether.
With literally billions of unwanted robocalls being made every month, they have become the largest source of complaints to the FCC, a very popular topic for a webinar and a great source of questions.
Here’s the Top 5 questions (and answers) from the “Battling Robocaller Fraud” webinar:
#1 How will stir/shaken affect class 4 telephony?
Answer: Implementing STIR/SHAKEN only impacts the originating and terminating carriers. The intermediary carriers (class 4) must pass the SIP identity headers without modification.
#2: Sounds great, but it depends entirely on the originating TSP to provide genuine authentication. What guarantees do we have this will be done by all originating TSPs, especially cellular carriers? What about calls that originate outside the US?
Answer: As the terminating service providers begin to flag calls without certificates as potential SPAM, or begin screening calls, the originators (both domestic and foreign) will have a strong incentive to add certificates to their calls. One of the beauties of STIR/SHAKEN is that the originators of bogus calls can be quickly found and dealt with by the regulators, making enforcement pretty easy.
#3: Does STIR/SHAKEN work only on the PSTN using SS7? What about OTT calls?
Answer: STIR/SHAKEN depends on IP infrastructure and the certificate is lost when handing a call over to a legacy TDM network. However, calls without a certificate can be flagged in the caller-ID by adding/substituting text in the caller-ID fields. Other applications like Skype SIP trunks could pass this information too.
#4: Does the size of the SIP packet require carriers to use TCP instead of UDP?
Answer: No, the identity certificates do fit within a SIP/UDP INVITE packet. However, there is a trend to consider SIP/TCP to handle traffic in the future.
#5: What role does TelcoBridges FreeSBC or Tmedia Gateways play?
Answer: When a call is originated, either the SBC or gateway passes the INVITE to the Authentication Server, which returns a signed SIP token to the SBC/gateway before passing the call to the network.

The phone rings and the number looks familiar, just a few digits off from your own. You wonder if a neighbor or possibly your child’s school calling, so you answer only to hear “Congratulations, you’ve been selected for a three night vacation package” You’ve been tricked into answering by a Robocaller, using caller-ID spoofing.

Over my career, I’ve been through plenty of software installation processes – some were of my own doing, others from open source or commercial products. Almost all of them are like watching a Rube Goldberg machine where an intricate sequence of interdependent steps occurs before your eyes. This week, I saw something very different.

Migrating communications applications to the cloud is much more than a technical challenge for service providers and enterprises. The challenge of the cloud is fundamentally based on a significant shift in business model.
