Structure (3 of 6) DEMO TIME 15:00-17:00+

• Demo Time will be divided into 2 sessions, its aim is to be informal

and provide ample networking opportunities for attendees to

consolidate their learning from the workshop:

• Demo presentation to the group: each demo will be 5 minutes long,

and 5 minutes for questions; and

• Demo one-on-one: attendees can chat one-on-one with the demo

presenters, notionally 30 minutes but can run on into discussions at

the bar through the evening.

Structure (4 of 6) DEMO TIME 15:00-17:00

• Zingaya ('Call' button for websites)

o Embed a 'Call' button into the website. Visitors can click that button and the call is

forwarded to the website operator's preferred land-line or mobile phone. All that is

required is a website; all the visitors need is a browser and microphone.

• Voxeo Labs (Ameche (new IMS/Web services), Tropo (leading call control API),

Phono (Web comms innovation)). They will demo Phono’s three types of

identity:

o Anonymous Identity: user lands on web site and is able to call directly into the contact

center

o Web Identity: use your web identity (twitter, foursquare, etc) to call each other.

o Telco Identity: Phono sessions can attach to the telco network and assume the real

identity (phone number) of the subscriber, allowing calls to be routed to both the mobile

and the browser simultaneously.

• Telestax

o Provides a complete stack from the client-side with Javascript JAIN SIP JS and WebRTC

as well as the server side with our SIP Over WebSockets. The demo will be a WebRTC

video conferencing and IM.


• Solaiemes WebRTC to Rich Communication Suite demo

o Demonstration of RCS messaging and WebRTC to access to media

components of devices to revamp the value of PSTN (and also mobile) lines.

Shows how Unified Communications could be built just a mash-up of

standards and APIs.

• Quobis

o Their approach to WebRTC is based on QoffeeSIP, a complete open source

Javascript SIP stack that can be used in a website to exploit all the multimedia

capabilities of WebRTC technology. Thanks to QoffeeSIP they have developed

a corporate WebRTC webphone that can interop with different network

devices; this webphone is going to be released at IMS World Forum event.

• Huawei leading NEP

o WebRTC / RCS insurance application demo


• Drum by NetDev (conference calls and online meetings)

o Allows providers of fixed, mobile and next generation VoIP services to deliver audio

conferencing as a direct, branded service. Hosted within your IP network on your

servers, Drum audio conferencing is a standalone software solution with an integrated

media server.

• Bistri (Social Video)

o Video chat with fun video effects, take screenshots of calls, share them with friends or

social networks. Bistri runs in the browser, so there's no need to install additional

software or plugins.

• apidaze.io

o Is a cloud communications API for developers with tools for building web or mobile

communication services, with a special focus on WebRTC. The demo will show how a

web developer can easily use the regular WebRTC API to place calls to external numbers

and audio conference rooms accessible from the PSTN too, using a simple raw

WebSocket connection that carries JSON text.

“Given the ability to deliver a royalty-free platform with no compromises on quality, we see no reason to include mandatory royalty-bearing codecs.”

“H.264 support is a requirement in some regulatory frameworks, such as emergency services. AMR narrow-band is playing a key role in mobile telephony and has a huge footprint.” “G.711 is universal, unencumbered, and widely implemented. A mandate for Opus will limit initial RTCWeb clients to use software-based codecs”

“We would like to recommend AMR-WB and EVS, since we expect them to be available in mobile chipsets.”

Optional Codec Diversity will Reign

Codec Wars

• G711a/u (RFC 3551): supported by all the devices. Needs to use a lot of

bandwidth.

• DTMF tones (RFC 4733, updates RFC 2833): needed for interactions with

several systems (for instance IVRs).

• Opus (RFC 6716): bitrate variable, low latency and high quality for human voice

and music. Specially designed for real time communications.

• In order to interact with VoIP systems, in several scenarios, it will need

transcoding or interworking of DTMFs (RFC 4733-> INFO, RFC 4733-> in-band,

etc).

• Can’t we just have both G.711 AND Opus? YES!!!!

Regardless Transcoding Will be Needed

WebRTC is a car without wheels!

WebRTC Triangle

• Both browsers running the same web application from web server

• Peer Connection media session is established between them

• Signaling is not standardized, could be SIP, Jingle, proprietary. Uses HTTP or WebSockets for transport

What WebRTC Means to Service Providers


NetHead CustHead

Our Industry’s Multiple Identity Disorder

A Telcos Two Unique Assets

Impact of WebRTC?

• Voice becomes just like all your other communications: organized into your

preferred social or office tools.

• It will be important for the IMS/RCS world to inter-operate with the

WebRTC world, currently these browsers will be a closed book to IMS. For

RCS to become pervasive, it cannot remain trapped in phones that have

implemented the IMS/RCS client.

• For all the OTT (Over The Top) applications, they can now use their

"directory service" i.e. your list of contacts also using their service to enable

Viber / Skype / Whatsapp everywhere. On your PC, smartphone, tablet, TV;

and they can offer chargeable services without Apple taking 30%.

• As long as you're data connected, communications is in the cloud, people

need only break out to PSTN when the other person is not data connected,

or the call quality is too low due to their internet connection. PSTN

becomes the communications path of last resort!

Impact of WebRTC?

• The company's website now becomes its call center front end. A weblog

becomes your personal communications assistant.

o Lots of start-ups in this space

• Communication service aggregators save customers running multiple clients

on their phone, that would run in the cloud and be controlled from the

browser.

• Click to call doesn't require an operator's voice network, just access to the

internet.

• Communications becomes like using any application on a smartphone,

users can add features, capabilities, people throughout a call, e.g. N-way

calling finally becomes simple and obvious with a simple point and swipe.

• Directory services become critical sources of value in connecting all the

different IDs: telephone numbers, SIP IDs (IDentifier), web session IDs,

other OTT IDs, etc.

Impact of WebRTC?

• VAS (Value Added Services) leaves telco. Any web developer can create value and

solve problems for customers, it the customer who will decide, and those developers

who fail fastest win the innovation race.

• Advertising finally enters the communications space, opening up business model

innovation.

• New CRM (Customer Relationship Management) methods: click from email, from

webpage, from app, from TV. The ability to communicate becomes embedded in

most transactions.

• QoS (Quality of Service) remains an issue, but for the people using Vonage and Skype

over the years will attest, QoS is rarely an issue.

• Your phone number is no longer relevant anymore. It's a gateway to the past.

Customers will only know the PSTN is involved because of the poor audio quality

(G.711) – BUT it is the customers only unique ID that they own.

• Gaming becomes interesting as all the devices become controllers using gesture

controls as well as the more traditional methods for network-based games.

Other Telco Impacts

• Impact of WebRTC on IP Messaging

o No need to for a messaging client to be downloaded

o Unified communications across voice, video and data

o Integrated experience across the web and communications client

• Opportunities

o Integrated charging

o Bundle APIs: WebRTC, RCS API, payment API, Call Control APIs

o QoS for those willing to pay (those running their business on your network)

• QoS API? NO! keep that for YOUR SERVICES

o Extend network services over the web

o Enhance enterprise Unified Communication offers

o Enhance OTT? Why they’re competitors!

o Gateway for the WebRTC codec mess

o Web phone for existing customers

Key Points

• Voice traffic is going to be through the web

• Browsers are the new endpoints

• A website of a company can be the call center

• An individual’s website (Facebook Page) their communications

assistant

• Security, identity and privacy are very important

o Telephone number is not important unless operators pull their finger out!

• New business opportunities abound

DO Communications

better thaN the

competition

ELSE BE AN ISP


What WebRTC Means to Enterprises


WebRTC and the Enterprise

• Enterprise is both excited and confused

about WebRTC

o Lower communication costs

o Lower IT costs as fewer clients to maintain?

o Better home and mobile comms that are

integrated with corporate systems

o New customer communications options

• Confusion arises from

o How to integrate

o What needs to change

o How does it work with legacy devices like

desktop videophones, mobile clients, desktop

phones, Microsoft Lync, Cisco UC, etc.

o What about our corporate firewall, what about

our SBC?

What Enterprises are Saying in Interviews on WebRTC

“WebRTC can lower our communications costs by 30%”

“WebRTC will finally give us a workable video communication solution

across all employees”

“WebRTC can make our contact center integrated into all channels, e.g.

Web and Mobile, improving customer service.”

“WebRTC can improve collaboration both internally and with our

partners as it just works between browsers.”

“WebRTC appears to be not part of the Telco’s offer, it is OTT.”

“WebRTC is confusing, it doesn’t work in most browsers.”

“WebRTC looks like a lot of hype, will it go the same was as VoIP?”

“WebRTC’s security, private, and ability to get hacked remain unclear”

“WebRTC will be killed by Microsoft!”

IT’s Technical Concerns

• Open standards makes it easier to hack

• Clientless, plugin-less browser audio and video for real-

time communications means we’re not dependent on

browser software suppliers

• Open-source codec

• ICE/STUN NAT transversal does not work all the time

• SRTP (Secure Real-time Transport Protocol) –

configuration and SSL certification issues

• No rules on signaling protocol – security issues?

• Multiplex RTP and RTCP on single port – management

issues?

• Multiplex audio and video on a single port – management

issues?

Understanding Old-IT

• Hardware endpoints with hard to upgrade software

• Few soft clients tied to the PBX

• Limited codec support, generally H.26x for video

• No experience with ICE, STUN, and STRP

• RTCP shall be on the RTP port +1

• Audio and Video are managed separately

• Look how long BYOD is taking

• Skype blocked, Facebook blocked,

• WebRTC blocked!!!!!!

Typical Large Enterprise Deployment

SBC

Router

Desktop Network

Telepresence Network

IT Generation Gap

Multiplexed Media STUN / ICE VP8

RTP/RTCP Separated

NO STUN /

ICE!!!!

H.26x

The Solution: A Gateway

• Signaling Gateway

o SIP stack in JavaScript?

o Break to SIP at the Gateway

• De-ICE

o Validate SDP ICE candidates

• De-Multiplex Media

• STUN Binding Handling

o Response to STUN bindings on

RTP channels

o Validate

• Transcoding

Use Cases

• Social Media and CRM Integration

• Video Conferencing to any device

• Inbound Click to call a New channel

• Can be deploy by outsourcers

• Calls in internal directories

In Summary

• Enterprise is interested in WebRTC BUT…

• Some Enterprises change even slower than Telcos….

• If Telco’s don’t help them, they will go to other service providers

• Gateway as a Service

o Signaling Conversion

o Media Interworking

Keep Calm and

Do SOMETHING

(Just NOT THROUGH

THE GSMA or TMF)
