The SIP Forum Announces Dates for SIPNOC 2019 — the Ninth Annual SIP Network Operators Conference

The three-day educational conference to be held in Herndon, VA, December 3-5, 2019; Will continue, and expand, focus on the SHAKEN Call Authentication Framework and expanding efforts to combat the Robocall epidemic

NORTH ANDOVER, MA (April 4, 2019) – The SIP Forum announced today that it will host the ninth annual SIP Network Operators Conference (SIPNOC 2019), a three-day educational conference focusing on the challenges and opportunities related to the deployment of SIP-based communications services.

SIPNOC 2019 will be held in Herndon, VA on December 3-5, 2019 at the Hilton Washington Dulles Hotel, and will build on the success of the previous SIPNOC event, which earned high praise from attendees for its educational, non-commercial and technical content that focused on the real-world challenges operators face when deploying SIP services in global IP communications networks.

SIPNOC 2019 will also continue and expand its focus on the SHAKEN Call Authentication Framework. Developed jointly by the SIP Forum and ATIS (the Alliance for Telecommunications Industry Solutions) to efficiently implement the Internet Engineering Task Force’s (IETF) STIR (for Secure Telephony Identity Revisited) standard, SHAKEN (for Signature-based Handling of Asserted information using toKENs) defines a mechanism to verify the calling number and specifies how it will be transported across communications networks.

Together, STIR/SHAKEN offers a practical mechanism to provide verified information about the calling party as well as the origin of the call — what is known as “attestation” — for the first time in the network. Giving service providers the tools needed to sign and verify calling numbers makes it possible for businesses and consumers to know, before answering, that the calls they receive are from legitimate parties. The STIR/SHAKEN Framework has been mandated by the Canadian Radio-Television and Telecommunications Commission (CRTC Decision 2018-32), and the United States Federal Communications Commission (FCC) has also endorsed its deployment.

SIPNOC 2019 will examine STIR/SHAKEN in detail, as well as cover lessons learned from recent SHAKEN trials and deployments, including the ground-breaking initial deployment by AT&T and Comcast that involves the exchange of authenticated calls between the two providers’ voice networks, Verizon’s deployment, and T-Mobile’s “Caller Verified” implementation of STIR/SHAKEN.

SIPNOC attendees include telecommunications providers, major backbone operators, interconnect and wholesale solution providers, ISPs, cable operators, wireless network operators and large enterprises deploying major SIP initiatives, as well as industry stakeholders in the Robocall and Caller ID Spoofing elimination/mitigation ecosystem, including governmental regulators and agencies, equipment manufacturers, enterprises, government agencies, contact centers, application providers and data analytics firms.

“As interest in STIR/SHAKEN, and actual SHAKEN implementations continue to grow within the communications industry, new technological, logistical and business challenges need to be addressed,” said Marc Robins, SIP Forum President and Managing Director, and SIPNOC Program Chair. “Prior to last year’s event, the network operator community had limited options for coming together to meet, discuss and share ideas and knowledge about SHAKEN implementation issues in a non-commercial, technically-oriented setting. SIPNOC provides that unique setting.”

SIPNOC 2019 will bring together leading technical minds from the telecommunications industry to learn, discuss and formulate new ideas and strategies concerning current-day challenges and opportunities for SIP-based carrier services in fixed and mobile IP network environments. The conference will feature well-known industry speakers and a number of highly technical educational and instructional panels and sessions. The SIP Forum will also host a number of networking events at the conference and offer a series of informal “Birds of a Feather” sessions, which encourage discussion of varying topics held in available meeting rooms and break-out areas.

At last year’s SIPNOC 2018, presentations were made by a number of industry professionals from organizations such as Comcast, Cox Communications, iconectiv, Metaswitch, Microsoft, Neustar, Ribbon Communications, and Sprint. Canadian Radio-Television and Telecommunications Commission (CRTC) Chairman and CEO Ian Scott; Current United States Federal Communications Commission (FCC) Chief Technology Officer Dr. Eric Burger; former FCC CTO and SIP Pioneer Dr. Henning Schulzrinne; and Jonathan Rosenberg, outgoing Vice President and Chief Technology Officer, Collaboration Technology Group, Cisco Systems, provided the keynote speeches.

“We created SIPNOC with the intention of providing a meeting place for the international community of communications engineers and network operations professionals who deal with the real-world intricacies of providing communications services on a day-to-day basis,” added Robins. “We want to build on the positive momentum from last year’s event where we were able to initiate discussions that are already having a tangible, positive impact on the global communications community. We expect this year’s event to be even more successful.”

 About the SIP Forum
The SIP Forum is a leading IP communications industry association that engages in numerous activities that promote and advance SIP-based technology, such as the development of industry recommendations; interoperability testing events including SIPit, and special workshops, educational activities, and general promotion of IP communications standards, services, and technology for service provider, enterprise and governmental applications. The SIP Forum is also the producer of the annual SIPNOC conferences (for SIP Network Operators Conference), focused on the technical requirements of the service provider community. One of the Forum’s technical activities is the development of the SIPconnect Technical Recommendation – a standards-based SIP trunking recommendation that provides detailed guidelines for direct IP peering and interoperability between IP PBXs and SIP-based service provider networks, and the SIPconnect Certification Testing Program, a unique certification testing program that includes a certification test suite and test platform, and an associated “SIPconnect Certified” logo program that provides an official “seal of certification” for companies products and services that have officially achieved conformance with the SIPconnect specification. Other important Forum initiatives include work in security, SIP and IPv6, and IP-based Network-to-Network Interconnection (IP-NNI) and the SHAKEN Call Authentication Framework.
