Real-time stuff for yourbrowser with no plug-ins
30“Given the ability to deliver a royalty-freeplatform with no compromises on quality, wesee no reason to include mandatory royalty-bearing codecs.”“H.264 support is a requirement in some regulatoryframeworks, such as emergency services. AMR narrow-bandis playing a key role in mobile telephony and has a hugefootprint.”“G.711 is universal, unencumbered, and widely implemented.A mandate for Opus will limit initial RTCWeb clients to usesoftware-based codecs”“We would like to recommend AMR-WB andEVS, since we expect them to be available inmobile chipsets.”
Codec Wars• G711a/u (RFC 3551): supported by all the devices. Needs to use a lot ofbandwidth.• DTMF tones (RFC 4733, updates RFC 2833): needed for interactions withseveral systems (for instance IVRs).• Opus (RFC 6716): bitrate variable, low latency and high quality for human voiceand music. Specially designed for real time communications.• In order to interact with VoIP systems, in several scenarios, it will needtranscoding 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

What WebRTC Means to ServiceProviders(c) 2012 Alan Quayle Business and Service Development
Impact of WebRTC?• Voice becomes just like all your other communications: organized into yourpreferred social or office tools.• It will be important for the IMS/RCS world to inter-operate with theWebRTC world, currently these browsers will be a closed book to IMS. ForRCS to become pervasive, it cannot remain trapped in phones that haveimplemented 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 enableViber / Skype / Whatsapp everywhere. On your PC, smartphone, tablet, TV;and they can offer chargeable services without Apple taking 30%.• As long as youre data connected, communications is in the cloud, peopleneed 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. PSTNbecomes the communications path of last resort!
Impact of WebRTC?• The companys website now becomes its call center front end. A weblogbecomes your personal communications assistant.o Lots of start-ups in this space• Communication service aggregators save customers running multiple clientson their phone, that would run in the cloud and be controlled from thebrowser.• Click to call doesnt require an operators voice network, just access to theinternet.• Communications becomes like using any application on a smartphone,users can add features, capabilities, people throughout a call, e.g. N-waycalling finally becomes simple and obvious with a simple point and swipe.• Directory services become critical sources of value in connecting all thedifferent 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 andsolve problems for customers, it the customer who will decide, and those developerswho fail fastest win the innovation race.• Advertising finally enters the communications space, opening up business modelinnovation.• New CRM (Customer Relationship Management) methods: click from email, fromwebpage, from app, from TV. The ability to communicate becomes embedded inmost transactions.• QoS (Quality of Service) remains an issue, but for the people using Vonage and Skypeover the years will attest, QoS is rarely an issue.• Your phone number is no longer relevant anymore. Its 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 gesturecontrols as well as the more traditional methods for network-based games.
Other Telco Impacts• Impact of WebRTC on IP Messagingo No need to for a messaging client to be downloadedo Unified communications across voice, video and datao Integrated experience across the web and communications client• Opportunitieso Integrated chargingo Bundle APIs: WebRTC, RCS API, payment API, Call Control APIso QoS for those willing to pay (those running their business on your network)• QoS API? NO! keep that for YOUR SERVICESo Extend network services over the webo Enhance enterprise Unified Communication offerso Enhance OTT? Why they’re competitors!o Gateway for the WebRTC codec messo 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 communicationsassistant• Security, identity and privacy are very importanto Telephone number is not important unless operators pull their finger out!• New business opportunities abound

What WebRTC Means to Enterprises(c) 2012 Alan Quayle Business and Service Development
WebRTC and the Enterprise• Enterprise is both excited and confusedabout WebRTCo Lower communication costso Lower IT costs as fewer clients to maintain?o Better home and mobile comms that areintegrated with corporate systemso New customer communications options• Confusion arises fromo How to integrateo What needs to changeo How does it work with legacy devices likedesktop videophones, mobile clients, desktopphones, Microsoft Lync, Cisco UC, etc.o What about our corporate firewall, what aboutour 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 solutionacross 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 ourpartners 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 onbrowser 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 – managementissues?• Multiplex audio and video on a single port – managementissues?
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!!!!!!

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 Serviceo Signaling Conversiono Media Interworking
