SIPNOC 2023 Overview

The SIP Forum Presents:

The SIP Network Operators Conference
“Focus on the Call and Text Authentication Ecosystem”

Hilton Washington Dulles Hotel, Herndon, VA – September 12-14, 2023

 Note: SIPNOC 2023 has concluded. This is an archived page that contains information about the event. For more information about upcoming SIPNOC conferences, please contact Marc Robins, SIP Forum President and Managing Director, at


Presented by the SIP Forum, the leading industry association focused on the advancement of IP communications products and services based on the Session Initiation Protocol (SIP), the 12th annual SIPNOC conference is a unique event for service providers and carriers to gather to discuss the challenges of deploying and implementing SIP-based communications technology, and to learn the best-practices and strategies that enable the successful and profitable operation of SIP-based services and applications.

Distinguishing the event from other industry conferences, SIPNOC 2023 is not a sales event, a marketing event, nor an event for corporate positioning.

SIPNOC 2023 Venue and Dates

In order to make travel to SIPNOC 2023 from points in Europe as well as locations in the United States as convenient as possible, the SIP Forum will be hosting SIPNOC 2023 in the Washington, D.C. metropolitan area at the Hilton Washington Dulles Hotel in Herndon, Virginia, just a few minutes from Dulles airport.

The dates for SIPNOC 2023 are confirmed for Tuesday, September 12 through Thursday, September 14, 2023.

For travel planning purposes, you should plan to arrive at the venue no later than Monday, September 11. The conference will start promptly the morning of Tuesday, September 12th and run all the way through Thursday, September 14, with timely and important sessions scheduled all the way to the very end! SIPNOC 2023 will end late afternoon, @5pm, on Thursday, September 14th, so you could plan on departing later that evening or night – or much better, on Friday, September 15th.

SIPNOC 2023 Program Committee and CFP

The SIPNOC Program Committee ensures that the SIPNOC 2023 agenda is built by a panel of operational experts and presented in a setting that will encourage the meaningful exchange of day-to-day operational experiences.

The program committee reviews workshop topic proposals and draft presentations, helping to ensure that the resulting discussions focus on implementation experiences and best practices relating to deploying SIP in the network.

The official SIPNOC 2023 Call For Presentations contains specific timelines and deadlines for submissions, and well as the various policies that govern the selection of content for the conference.

Focus on the Call and Text Authentication Ecosystem

SIPNOC 2023 will return to live, in-person proceedings, and continue and expand its focus on the broad Call Authentication ecosystem and the continuing efforts to eliminate illegal Robocalls, Caller ID Spoofing, and Robotexts, as well as other related topics, including the STIR/SHAKEN Framework, Call Analytics and Vetting, Branded Calling and Rich Call Data, International Traceback and STIR/SHAKEN adoption, KYC initiatives, Enterprise requirements and challenges, new SMS Text Authentication initiatives, associated Federal and State regulatory and enforcement actions, and more.

For this year’s conference, a unique three-day agenda has been specifically developed for industry stakeholders in the Call Authentication ecosystem, including telecommunications providers, major backbone operators, interconnect and wholesale solution providers, ISPs, cable operators, wireless network operators and large enterprises, as well as industry stakeholders in the Robocall/Robotext 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.

To address unwanted and illegal Robocalls, the SIP Forum and the Alliance for Telecommunications Industry Solutions (ATIS) formed the Network to Network Interface (NNI) Joint Task Force to develop standards to verify and authenticate caller identification for calls carried over an Internet Protocol (IP) network using the Session Initiation Protocol (SIP). The outcome of this effort has been the SHAKEN Call Authentication Framework.

Comprised of presentations and panel discussions given by the experts responsible for the development of the STIR/SHAKEN Framework as well as leaders in other areas of the Call Authentication industry, including “Know Your Customer” solutions providers and call analytics experts, the SIPNOC 2023 agenda will examine in detail the work and milestones of the ongoing efforts to combat telecom fraud. With currently more than 400 participants, the joint SIP Forum and ATIS IP-NNI Task Force has been meeting regularly for the past several years to define call authentication specifications and is comprised of telecommunications technical experts representing a range of telephony service providers and suppliers, both large and small, which serve both consumers and businesses.

Important, associated domestic and international regulatory issues will also be on the agenda, as the United States Federal Communications Commission, the CRTC in Canada, and other International regulatory agencies have all endorsed this important work.
