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.

10:00am-10:15am: 15 Minute Break

10:15am-10:45am: Taking the "Custom" out of "Customer": Appropriate Productization for Voice Service Providers. Presented by Mark Lindsey, ECG.

Engineers live to build things, and solve new problems. But if every customer becomes an opportunity to design afresh, then no two customers will be alike. The service provider that prides itself on "custom tailored solutions" must realize that such flexibility requires engineering-level support for practically all troubleshooting, and engineering-level support for every single sale.

The alternative extreme is the Bellhead way: where no product is released until it is fully planned, engineered, tested, documented, and supported by trained workmen. This process of productization can take years. But the result is something known to work which can be applied repeatedly by lesser-skilled staff, or even automated.

This talk describes that great value in a middle way: where custom engineering is minimized, and standardized products are planned and reasonably tested before release or deployment with customers. The surprising advantage is that sales appears to become easier, and deployments less costly with reusable components and standardized network designs. Service providers with strict productization appear to expand much faster than those built solely on custom engineering. We give concrete examples of the kinds of productization we have seen in use that help VoIP Service Providers to improve their networks and support customers better.

10:45am-11:30am: SIP Trunk Design Patterns. Presented by Robert Kinder, Cox Communications

SIP Trunking Design Patterns are reusable solutions for frequently occurring customer implementations. The concept is very similar to software engineering design patterns to solve common programming problems. SIP Trunking Design Patterns are used by Sales Engineers to propose the best solution to meet the customer’s requirements and by order entry and auto-provisioning BSS/OSS applications to configure the network.

The SIP Trunking Design Pattern session will include diagrams and applications for the following:

• Single Site: Small Medium Business (SMB)
• Multi-Site Shared Capacity: SMB cost economy
• Trunk Group Redundancy
• Geo-Redundancy: Load Balancing, Route Prioritization, Multi-Site Sequential Route Advance/Overflow, Primary/Secondary Data Centers, Symmetrical Failover with DID-based Routing Optimization
• SIP Trunk to ISDN PRI Failover: Alternate platform and network survivability for data centers and remote survivable gateways.
• Business Continuity Behaviors (BC) and Options
• User configured Business Continuity features (Call Forward Not Reachable, Call Forward Always, Personal Mobility, etc.)
• Automatic Business Continuity features (trunk group reroute, route exhaustion)

11:30am-12:00pm: The Growth of Robocalling SPIT. Presented by Dan Weber, Personal Time Software.

Just about ten years ago, telemarketers presented the biggest threat to consumer privacy and use of the telephone system. In response to the growing number of complaints by being called from people at all hours of the day, the FTC created the National Do Not Call list. Everyone is familiar with this list and how it promotes consumer privacy by allowing consumers to opt-out of receiving unsolicited calls.

In the wake of VoIP telephony, a new form of SPAM started flooding our telephony system. Also known as a form of SPIT, robocallers have now superseded the telemarketers. Instead of hearing a real person call, you hear a voice recording, and most of these calls are illicit. Due to the nature of VOIP being cheap and its freely accessible nature, these calls are difficult to handle, and the regulatory bodies as well as consumers are looking for solutions at the carrier level to protect them.

With potential for new regulatory mandates on the horizon, our presentation seeks to start an open discussion on the ways that carriers can begin to address this problem in beneficial ways before it is required of them to do so, potentially at their own cost.

12:00pm-1:15pm: Lunch

1:15pm-2:15pm: SIP Forum Task Group Update: Introduction and Moderation by Spencer Dawkins, SIP Forum Technical Director; Presenters include Mary Barnes, Polycom and SIP Forum; Robert Kinder, Cox Communications; Carl Klatsky, Comcast; Alan Johnston, Avaya and SIP Forum; Gonzalo Salgueiro, Cisco Systems and SIP Forum; David Hanes, Cisco Systems; Richard Shockey, Shockey Consulting and SIP Forum.

This special session will brief the SIPNOC community on the various SIP Forum task group initiatives and works in progress, including the SC-IT (SIPconnect Interoperability Testing) Task Group, the SIP and IPv6 Task Group, the Fax-over-IP Interoperability Task Group, the User Agent Configuration Data Profile Task Group, and the VRS (Video Relay Services) Task Group.

2:15pm-3:15pm: SIPNOC 2013 Tutorial: An introduction to WebRTC: Contributing Technologies and Implications on SIP Communications. Presented by Steve Mckinnon, GENBAND.

This presentation will cover the various technologies that combine to make up the webRTC real time communications browser capability set, and describe the implications of those technology and standards choices for over the top and SIP Communications Networks alike. Where possible the various conflicting approaches will be discussed and evaluated.

3:15pm-4:30pm: SIPNOC 2013 Super-Session -- Panel Discussion: FCC Policy and Regulatory Update and the AT&T Trial Proposal. Moderator: Richard Shockey. Panelists include Harold Feld, Senior Vice President, Public Knowledge; Hank Hultquist, AT&T; and Michael Romano, NTCA.

The Transition from TDM to all SIP based IP networks is well underway. AT&T recently made an extraordinary proposal to the FCC regarding SIP IP interconnection. In response, the National Telecommunications Cooperative Association, representing many rural telecom operators, expressed general support for the concept with some reservations. This proposal has sparked considerable debate within the industry on what it means and what are the technical, regulatory and public policy issues involved. This panel will review the AT&T/NTCA proposals and its current status.

4:30pm-4:45pm: 15 Minute Break

4:45pm-5:15pm: Communications Service Providers and Threat Intelligence Sharing. Presented by Eric Burger, Georgetown University.

Past SIPNOC discussions raised the interest in the operator community to figure out how to share information on fraud, cyber attacks, and detected vulnerabilities. So, we have the desire to share operations intelligence. However, is it legal? For that matter, with the recent Executive Order and Presidential Policy Directive, is it legal not to share intelligence?

Since this is SIPNOC, not a Bar Association conference, and the presenter is not a lawyer, the talk will focus on the technologies and architectures for automated information sharing.

It will touch upon policy, regulatory, and legal issues as they do impact the technology and might impact your operational environment. The hope is to raise awareness that the community is starting to address the operators' needs for information sharing and to raise the discussion on how to actually share information.

5:15pm-6:15pm: Panel Discussion: Anatomy of a VoIP DMZ. Moderated by Dan York, ISOC. Panelists include Jim Gast, TDS Telecom; and Mark Lindsey, ECG.

This special panel discussion will present ideas for provisioning phones safely and securely and then intentionally deciding to use (or not to use) SIP over TLS and SRTP.

In addition, the discussion will cover the motivation for a DMZ; the secrets that should be protected (e.g. provisioning password, web portal password, SIP authorization password); Testing the factory-installed CERT before giving out important secrets in config files; Using a service-provider self-signed CERT so that phones that can’t prove their identity don’t learn any important secrets; The costs and benefits of HTTPS vs. HTTP; and the whether it makes sense to put a layer-3 firewall in front of a Session Border Controller.

7:00pm-10:00pm: SIPNOC 2013 Beer and Gear Networking Reception and Attendee Dinner

7:30pm-8:30pm: BOF -- VoIP Security. BOF Leader Dan York, ISOC.

This special panel discussion will explore the various issues regarding the interworking between the web browser and SIP interfaces.

10:45am-11:45am: Panel Discussion: IPv6 And SIP – Myth or Reality? Moderated by Dan York, ISOC. Panelists include Chris Wendt and Carl Klatsky, Comcast; and James Rafferty, Dialogic.

This special panel session will put together a group of people involved with IPv6 to dig into what is *really* happening with IPv6 and SIP. The panel would answer questions like:

• What's going on with SIP over IPv6?
• What are the main challenges to using SIP with IPv6?
• What do we know about the status of current equipment working with IPv6?
• What is the SIP Forum doing to help advance the state of the art?
• Where do we see SIP and IPv6 going?

11:45am-12:15pm: Carrier Support for Codec Handling. Presented by Jack Shields, XO Communications.

Customer and equipment needs over the past five years have changed. In the early days, initial carrier offerings had limited choices and made the choice of non-G.711 codecs difficult

As time progressed, competition forced a more universal service where customers were allowed the flexibility to use codecs of choice. The "job" then became to meet customer requirements at minimal cost.

Today, there is a growing trend to push codec negotiation back onto CPE equipment and concentrate on a marriage of equals. Essentially, to provide end points that offer a large range of codecs and allow and encourage end-to-end negotiation, and make carrier equipment more transparent.

This session will explore this trend, and how it can effectively lower the cost of providing service and at the same time increase call quality.

12:15pm-1:30pm: LUNCH

1:30pm-2:30pm: SIPNOC 2013 Super-Session: IETF/Standards Update. Presented by Mary Barnes, Polycom, IETF and IAB.

This session provides an overview of current SIP and related standards activities underway in the IETF. Conferees will come away with insight into future network and endpoint functionality, as well as understand the process for evolving and developing SIP and other Real-time Applications and Infrastructure protocols.

2:30pm-4:00pm: SIPNOC 2013 Super-Session -- Panel Discussion: NENA and SIP in Emergency Services. Moderated by Richard Shockey, Shockey Consulting and the SIP Forum. Panelists include Roger Hixson, NENA, who will present a tutorial at the beginning of the session, and Laurie Flaherty, NG9-1-1 Program Lead, National Highway Safety Administration, U.S. Dept of Transportation.

Concurrent with the ongoing transition to all SIP networks the Public Safety community also has proposals to transition the entire 9-1-1 ( 1-1-2 in Europe) system to an all IP-SIP Next Generation (NG 911) network based on the National Emergency Number Association NENA i3 and IETF ECRIT architecture. In addition, a brand new Public Safety Radio Access Network based on LTE and VoLTE for First Responders is being built called FirstNet in the United States. The panel will review the basic NENA/IETF emergency services architecture and review possible impacts and future requirements on service provider voice networks as well as SIP based PBX systems.

4:00pm-4:30pm: SIP Safari: Real Tales From The Wild. Presented by Gernot Scheichl, Edgewater Networks

This session will review real-world challenges for MSOs to ubiquitous SIP connectivity. While SIP provides a strong framework, significant interoperability challenges remain due to differences in implementation. To address the interoperability challenges, protocol mediation is required, including various techniques in resolving behavioral differences, syntax differences, header manipulation, security and more. The presentation will characterize the interoperability challenges discovered through real-world deployments and extensive multi-vendor SIP interoperability testing and it will offer specific solutions for MSOs to provide a consistent signaling interface at the edge so they can efficiently scale their enterprise SIP services.

4:30pm-5:00pm: HTML5 WebRTC and SIP Over WebSockets. Presented by Thomas Quintana, TeleStax

HTML5 and WebRTC are free, open specifications that promise to enable rich, high quality, real-time communications applications to be developed in the browser via simple Javascript APIs and HTML5. Major browsers already support or will support it soon natively.

This talk will present an overview of WebRTC, why it can be highly disrupting for existing Operators and change the Telco industry. It will ask the question of where to place SIP when using WebRTC and describe SIP Over WebSockets, and how it can help operators bridge or expose their existing infrastructure to WebRTC, as well as what has to be done to accomplish it on a technical level and address concerns about Security, NAT Traversal, changes from RFC 3261, and other leveraged RFCs. It will also present the current challenges faced by both WebRTC and SIP Over WebSockets, and a live demo of a 1-to-1 WebRTC Video Conference will also be performed with a description of the call flow both at the signalling and media levels.

5:00pm-6:30pm: Day 2 Networking Reception (includes drinks and hors d'oeuvres)

5:15pm-6:15pm: BOF Time.

9:00am: Day 3 General Session Begins in Luray Ballroom A-C.

9:00am-9:30am: VoIP Theft: Werewolf or Hydra? Presented by Mark Lindsey, ECG.

The Bad Guys are stealing service from any VoIP service provider they can. The attacks come through several vectors, but typically they (a) discover SIP credentials, then do direct SIP registration; or (b) compromise a customer VoIP device, then route calls through it.

Many products and practices have sought to address the problem. While some powerful techniques have been produced, none of these are a silver bullet that stops the problem and allows the flexibility needed for modern, open VoIP Service Providers.

Nevertheless, a combination of techniques is making real progress. Based on experience at multiple major US VoIP service providers, we show that a particular combination of ingredients, when applied properly and in concert, neutralizes all of common attacks.

This talk presents the prevalent attack techniques, the combination we're having success with, the contribution of each element of protection, how the combination is working in practical service providers.

9:30am-10:00am: Who are You Really Calling? How DNSSEC Can Help. Presented by Dan York, ISOC.

When Alice calls Bob, how does she know that she is really communicating with Bob's SIP server? Sure, her software grabs a SRV record for Bob's server from DNS, but how does Alice's systems know whether that is the *correct* DNS record for Bob's server? What if an attacker were able to inject DNS records that redirect Alice's call to another system? What if there were a way that the SIP endpoints could be certain about the address of the other system they want to call?

In this talk, Dan York will explain how DNS Security Extensions (DNSSEC) works and how it can apply to SIP communications. He will demonstrate one of the existing implementations in the Jitsi softphone and outline how the system can work. He will also dive into a new protocol, DANE, that allows SSL/TLS certificates to be stored in DNS and explore how this could potentially be used for the security of SIP endpoints.

10:00am-10:30am: SIP Marketplace Ecosystem Health Check. Presented by Bruce Page, Current Analysis.

This session complements the SIPNOC technical program with a review of the current and near-future state of the SIP market ecosystem.

Technical standards and interoperability testing are the foundation for SIP's further development as the basis for next-generation communications products and services.

This session will review the drivers and barriers to SIP adoption in carrier networks and customer-premises equipment and software applications; examine lessons learned from a number of successful SIP market-development initiatives; and consider the possibility that the communications market may be nearing a "tipping point" with regard to wide-scale adoption of SIP-based communications infrastructures.

10:30am-11:00am: HD Voice Deployment: Challenging Road from Concept to Realization. Presented by Manpreet Singh, iBasis.

With voice becoming a commodity, users want more out of what they pay today. For any operator, quality has been the biggest issue when doing calls between 2 users, whether they are on fixed lines, mobile lines or a soft client sitting on their PC or their mobile headset. High Definition voice promises a clear, crisp and stereo quality voice experience which users are already accustomed to seeing on their HD enabled TV sets. But providing this service is not easy when it comes to voice enabled networks.

Here are some of the challenges we face:

1. Fixed headsets are still PCM-based and large majority of mobile handsets are AMR-based, and the penetration of IP-based fixed headsets and AMR-WB based mobile handsets is still low.
2. Mobile networks have not upgraded their core to support BICC protocol which supports HD negotiation.
3. Mobile networks which are HD enabled are not ready to expose national networks to international networks causing international calls to be still be NB even when the core is HD.
4. Different implementations of AMR-WB codecs causing interoperability issues which is blocking the interconnection of various mobile networks.
5. Widespread adoption of IPX is not here yet, which is the baseline IP network to support this.
6. OTT providers are coming in the mix with HD codecs like SILK and OPUS which are not widely supported across any mobile or fixed network operator.
7. The emergence of LTE is putting HD on the backburner.

There are many more things which are hindering the adoption of HD -- especially across International boundaries. In the future, the emergence of LTE will make it easier to do HD across domains. Existing deployments are happening but there are many interoperability issues that need to be looked at more closely to bridge this gap. It all comes down to having an IPX provider be a bridge between 2 operators and join 2 heterogeneous HD islands for greater user experience.

11:00am-12:00pm: BOF -- WebRTC. BOF Leader: Dr. Alan Johnston, Avaya and SIP Forum.

12:00m-1:15pm: LUNCH

1:15pm-1:45pm: It's the End of the PSTN as We Know It (And I Feel Fine). Presented by Chris Wendt, Comcast.

The user experience of PSTN connected telephony services has suffered dramatically in the past few years. The telephone ring used to be a welcome intrusion in our day to talk to friends, family, or colleagues. Now evolving social contexts and norms, the need/desire to multitask, and the threat of telemarketing and robo-calling have conditioned us to often cringe when we hear a ring, pause to guess who might be on the other end, and debate whether we want to answer or just turn off the ringer. What happened? What can we do as an industry to revitalize consumer interest in federated telecommunications services? How might emerging buzz around WebRTC have a role in this new world? This talk will explore and propose what redefining a telecommunications service provider means in this new world.

1:45pm-2:45pm: SIPNOC 2013 "Unconference" Session

Unconferences, sometimes referred to as "colloquiums", are the rage in the visual-design and some of the coding communities. Here's how it works: Attendees write down a few ideas for an interesting topic to discuss. Then the attendees would review the topics raised, and vote for the ones they like most. The winners get to stand at the podium and talk about the subject for a short time, usually around 10-15 minutes.

2:45pm-3:15pm: SIPNOC 2013 Capstone Session
