SIPNOC 2019 Overview

The SIP Forum Presents:

The SIP Network Operators Conference
“Focus on STIR/SHAKEN”

Hilton Washington Dulles Hotel, Herndon, VA – December 3-5, 2019

Note: SIPNOC 2019 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 This is an archived page that contains information about the event.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 ninth 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 2019 is not a sales event, a marketing event, nor an event for corporate positioning.

SIPNOC 2019 Venue and Dates

In order to make travel to SIPNOC 2019 from points in Europe as well as locations in the United States as convenient as possible, the SIP Forum will be hosting SIPNOC 2019 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 2019 are confirmed for Tuesday, December 3 – Thursday, December 5, 2019.

SIPNOC 2019 Program Committee and CFP

The SIPNOC Program Committee ensures that the SIPNOC 2019 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 2019 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 STIR/SHAKEN Framework

The primary focus of SIPNOC 2019 is on the STIR/SHAKEN Framework and it’s role in the mitigation of Robocalls and Caller ID Spoofing, as well as other related topics. For this year’s conference, a unique three-day agenda has been specifically developed for industry stakeholders in the Robocall and Caller ID Spoofing elimination/mitigation ecosystem, including service providers seeking to deploy STIR/SHAKEN solutions, governmental regulators and agencies, equipment manufacturers, enterprise and government agency 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, the SIPNOC 2019 agenda will examine in detail the work and milestones of this Task Force, and will also include the efforts of various industry stakeholders. With currently more than 200 participants, the NNI Task Force has been meeting regularly for the past five years to define specifications to support SIP-based Service Provider to Service Provider IP Interconnection. The Task Force 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 OFCOM in the United Kingdom, have all endorsed this important work.

The ATIS and SIP Forum SHAKEN Call Authentication Framework consists of a three-phase approach to solving the issue of caller identification, using a digital certificate scheme to “verify and authenticate caller identification for calls carried over an Internet Protocol (IP) network.”

Phase 1 consists of the development of the SHAKEN framework, based on the protocols developed by the IETF’s STIR working group (the STIR framework), and describes the operations necessary for making an authenticated telephone call using the SHAKEN framework.

Phase 2 consists of the development of a “Governance Model and Certificate Management for the Trust Anchor,” describing the way in which entities will be granted the trust necessary to vouch for call authenticity, and the organizational structures needed to manage this process. Specifically, this work introduces a governance model and defines X.509 certificate management procedures. Certificate management provides mechanisms for validation of a certificate and verification of the associated digital signature, allowing for the identification of illegitimate use of national telecommunications infrastructure.

Phase 3 consists of the development of a “Call Validation Display Framework” that will recommend how to display SHAKEN/STIR information to contact center professionals, enterprise users, and consumers.

Who Should Attend SIPNOC 2019?

With a primary focus on the implementation of STIR/SHAKEN and the Robocall Mitigation industry eco-system, SIPNOC 2019 is a special event for operational personnel and engineers from service providers of all stripes, and for individuals that are part of the Robocall and Call ID Spoofing solutions ecosystem, including:

SIPNOC 2019 Sponsors

We are very proud to have the following companies help support SIPNOC 2019 through their generous support as event sponsors:

SIPNOC 2019 Diamond Sponsors

iconectiv, the authoritative partner of the communications industry, has signed the agreement to serve as U.S. Secure Telephone Identity Policy Administrator (STI-PA) for the FCC-endorsed ATIS-SIP Forum SHAKEN (Signature-based Handling of Asserted information using toKENs) — the industry-wide solution to mitigate illegal robocalls and help consumers once again trust their calling number displayed on their caller ID.

As policy administrator, iconectiv serves in an operational role and has been selected by the industry led Secure Telephone Identity Governance Authority (STI-GA) Board to apply and enforce the rules defined for the SHAKEN framework. These rules specify a practical mechanism for service providers to authenticate calls and let consumers know that the telephone number displayed on the caller ID is accurate.  As the policy administrator, iconectiv will confirm which service providers are authorized to request certificates and review and approve Certificate Authorities to issue them. For more information about iconectiv, please visit

Nobody likes fraudulent robocalls. That’s why Comcast is excited to announce that Comcast and A&T have taken an important step forward to address the problem – an exchange of authenticated calls between two separate providers’ voice networks that is believed to be the nation’s first.

This milestone helps pave the way for AT&T and Comcast to begin offering authentication on calls between networks to customers later this year. Customers could soon start to see verified calls not only from callers using the same provider, but more importantly, from other participating providers.

The test used phones on the companies’ consumer networks – not in a lab or restricted to special equipment. It was conducted March 5, 2019, between AT&T Phone digital home service and Comcast’s Xfinity Voice home phone service.

The calls were successfully authenticated and verified using the SHAKEN/STIR protocol – believed to be an industry first for calls between separate providers.  Comcast and AT&T played key roles in developing and refining SHAKEN/STIR, which is an important tool in the broader effort to combat fraudulent robocalls.

In addition to its leadership role in developing and implementing SHAKEN/STIR, Comcast’s Xfinity Voice works with Nomorobo to make robocall blocking technology available to the vast majority of Xfinity Voice customers. Customers can sign up to use Nomorobo service using their Xfinity username and password. Detailed instructions for using Nomorobo with Xfinity Voice are available here.
