SIP Training Day — Expanded to Include New WebRTC and IMS/VoLTE Workshops!

Back by popular demand, the SIP Forum will once again not only offer a day of specialized SIP Training at SIPNOC 2016 presented by the expert trainers of ECG, but also new additional training in WebRTC and IMS/VoLTE – available to all SIPNOC 2016 attendees at no additional cost!

This Training Day is scheduled for Tuesday, June 21, 2016, and is designed to offer SIPNOC 2016 attendees relevant training on the SIP protocol, WebRTC and IMS/VoLTE, as well as provide insights and considerations related to a variety of technical implementations. Ultimately, the goal of these special training workshops is to help ensure that SIPNOC 2016 attendees get the most out of the technical presentations that follow over the course of the conference.

In contrast to video training and online courses available elsewhere, during the Training Day at SIPNOC 2016 you’ll be working with experienced trainers and experts who build, improve, and debug VoIP, WebRTC, and IMS/VoLTE systems every day.

A new WebRTC Primer, presented by SIP and WebRTC expert Dr. Alan Johnston, will provide you with the latest about WebRTC standards and deployments and real-world interoperability, and get you started in analyzing, coding, and troubleshooting WebRTC applications! Starting with the basics, we will introduce WebRTC and show you how to setup a development environment on your PC for node.js. You will learn WebRTC APIs such as getUserMedia and RTCPeerConnection on Chrome and Firefox browsers. We will introduce media protocols such as SRTP, and NAT traversal protocols such as STUN, TURN, and ICE. You will learn how to analyze WebRTC packets using Wireshark and interpret WebRTC internal information from the browsers. We will step you through a simple signaling channel, client-side, and server-side programming. Key topics such as security including DTLS and privacy will also be covered.

The IMS/VoLTE Training, presented by Manpreet Singh of iBasis, will cover the evolution of the LTE network and its evolution from 3G. Attendees will be provided with a background on doing voice over a 3G network and a typical 3G network topology, and the network topology of a LTE network including IMS. VoLTE fundamentals will be covered, including SIP-IMS; Description of the IMS network elements; Description of the EPC core; Domestic call flows; Roaming call flows (including preconditions) including Local Breakout with HPMN Routing, Local breakout with VPMN routing, and S8 home routing; and a discussion of important SIP headers for volte signaling. Other areas covered include Charging models and Quality of Service implementation.

At the SIPNOC 2016 SIP Training Day, you’ll be able to brush up on the essentials of VoIP Network Operation. ECG’s training will deliver insights from the trenches of Interop troubleshooting and the network engineering of the boardroom. Instead of a rehearsal of IETF RFCs, you’ll see how VoIP is really done in live networks, today.

SIPNOC 2016 Training Day Topics will also Include:

  • SIP Call Control. How do calls get started? How are they changed? How is the codec negotiated? How is incompatibility worked out?
  • Session Border Controllers. When are these devices used? How does an SBC improve security? How does NAT interfere with normal VoIP? How does an SBC solve the NAT Traversal problem for VoIP? How is SIP Trunking and Carrier Peering Established? How can audio and video be improved by an SBC?
  • VoIP Media. How is audio and video encoded for transmission? What are codecs, and how are they selected? What is RTP? What is a jitter buffer, and what problems can it solve? How does Network congestion and QoS affect the user experience?
  • VoIP/IMS Network Components. What are the common equipment and terms you’ll find used in VoIP/IMS networks? Which components are often combined? How do component failures affect ongoing phone calls?
  • The Future for VoIP Networks. What are the open challenges in most VoIP networks? What are the trends coming from software and hardware vendors? How does SDN and NFV affect network growth? How do you prepare to support VoLTE, and IPv6?

An added bonus: All training day participants will receive a hardcover training manual with detailed notes and diagrams covering the SIP Training topics.

SIPNOC 2016 Conference Topics

SIPNOC 2016 will focus on issues critical to the reliable and successful deployment and operation of SIP-based services in today’s IP-based network environment.

Special Keynote Address by Henning Schulzrinne, Former CTO, FCC

The SIP Forum is very proud to have Henning Schulzrinne return to keynote this year’s SIPNOC event. Dr. Schulzrinne is universally acclaimed as the Father of the SIP standard.

Dr. Henning will speak on the topic of “New Frontiers in Multimedia Communications”. While SIP-based communications is still dominated by voice and conference-style video, new challenges and opportunities are emerging. He will address four related topics:

  1. Phone numbers are no longer the dominant communication identifiers, but no viable alternative has emerged. How should we find, identify and discover participants?
  2. Messaging systems using standards such as SIMPLE and XMPP have faded, replaced by closed systems both for consumer and enterprise use. Why did this happen and is there a role for a standards-based, open collaboration system?
  3. Communications services for people who are Deaf or hard of hearing are changing more than they have in the past decade. Real-time text, automated speech-to-text systems and partial replacement of relay services by direct consumer-to-enterprise American Sign Language communication offers new opportunities for better services and may impact what enterprise call center applications and smartphones are expected to be capable of.
  4. One of the most valuable Internet of Things application is video, whether the video feed is streaming traffic data or watching a pet at home. How can we better integrate IOT with SIP-based applications?

As CTO of the FCC from 2012 to 2014, Schulzrinne guided the organization’s work on technology and engineering issues, together with the FCC’s Office of Engineering and Technology. He advised on matters across the agency to ensure that FCC policies are driving technological innovation, including serving as a resource to FCC Commissioners. Schulzrinne joined the FCC in 2010 as an Engineering Fellow.

Dr. Schulzrinne also serves as Julian Clarence Levi Professor of Mathematical Methods and Computer Science and Professor of Engineering at The Fu Foundation School of Engineering at Columbia University. Over the course of his career, he has published more than 250 journal and conference papers and more than 70 Internet Requests for Comment (RFCs) – working to shape the key protocols for enabling voice-over-IP (VoIP) and other multimedia applications, including the Session Initiation Protocol (SIP) which have become Internet Standards. His research interests include Internet multimedia systems, applied network engineering, wireless networks, security, quality of service, and performance evaluation.
