The Problem The Solution - Voice Activated In-Call Assistant
Taking notes while driving is dangerous. What if Through the power of your voice: record calls, take notes that upload to Evernote, listen
you could activate an in-call assistant to take and send email / SMS / IM / Tweet / to do list / blog posts, receive whisper meeting alerts
notes, transcribe the call to text and send you an during calls that only you hear, add people to calls, divert calls to other devices, check your
email or MMS message when you hang up? calendar to add or change appointments, and lots more…

- 4. WebRTC is a new API for embedding real-time communications into web sites and browser-based applications Voice, Video and even Screen Sharing become standard capabilities of the modern web browser

- 7. API or VoIP 2.0? WebRTC is more than an API... It’s a simplified profile for real-time communications on the Web Expect a wave of ‘WebRTC-compatible’ devices and non-browser platforms Mobile, desktop embedded systems will soon begin shipping with compatible stacks, thereby increasing the already staggering number of RTC-ready platforms and devices.
- 8. Impact of WebRTC ✓ ‘Calling’ becomes a common feature within social networks and business applications like Facebook, LinkedIn, and SalesForce.com ✓ Company websites become the contact center (i.e. real click to call) ✓ Tons of new collaboration and ‘virtual meeting’ sites will give products like GoToMeeting and WebEx a run for their money. ✓ Mobile games makers will further incorporate live video and real-time image processing to provide immersive augmented-reality experiences ✓ Home surveillance and remote monitoring are more convenient and affordable as sensors, video codecs and network stacks become commoditized ✓ Expect terms like ‘life streaming’ and ‘crowd vision’ to enter the our lives

- 12. ROAP vs JSEP ROAP was the initial attempt at providing an offer/answer model for WebRTC. After some experimentation the working group concluded that ROAP put too much state in the browser making it difficult, and in some cases impossible, to implement a variety of advanced use cases and failover models. JSEP was introduced in Feb‘2012 to address these shortcomings and is now the standard model for setting up PeerConnections A great retrospective can be found in the JSEP proposal: http://tools.ietf.org/html/draft-uberti-rtcweb-jsep-02

- 15. MediaConstraint getUserMedia() getUserMedia()
- 16. PeerConnection MediaConstraint getUserMedia() getUserMedia()
- 17. Putting it all together... Caller creates new PeerConnection • Invokes getUserMedia() • Adds Stream to PeerConnection • Sends stream ‘description’ to remote party Callee received description and invokes createAnswer() • Sends his own description to caller Caller uses remote description to complete the connection
- 19. WebRTC Signaling
- 20. Signaling?!? I thought WebRTC was P2P! This is a common misunderstanding WebRTC enables peer-to-peer media but the connection must still be setup via some form of signaling. Typical signaling involves the help of a web server with enough context to route session descriptions to each participating browser or network.
- 21. WebRTC Signaling Triangle Web Thingy 1 2 4 3 5 Bob Alice
- 22. So what’s the protocol? It’s whatever you want :-) WebRTC does not specify a signaling protocol The reasons are simple: • WebRTC is a media technology (i.e. not just for calls) • SIP is flexible but way too complicated • Many sites like Facebook already do signaling
- 23. Facebook Signaling Bob likes your status “Finally!” Bob Alice
- 24. Facebook Signaling Call Alice Bob is Calling... Bob Alice
- 25. Picking a Web-signaling protocol Web signaling introduces new challenges not generally addressed by traditional signaling protocols Some dimensions to consider when shopping for a WebRTC stack: ✓ Single Sign-on ✓ Connection Resume ✓ Multi-endpoint Registration ✓ Mobile Notifications / App ‘Background’ Support ✓ Chattiness / Battery Life

- 38. WebRTC Frameworks The lack of signaling coupled with incompatibilities between WebRTC implementations has created a need for libraries and frameworks to accelerate development and lower the barrier of entry for new applications. Just as jQuery normalized HTML rendering and event models between browsers, this new wave of WebRTC frameworks will provide longevity and backwards compatibility for developers; allowing them to focus on features and creating value for their users.

- 40. WebRTC Gateways WebRTC Gateways are server-side nodes that bridge Web clients into an existing network (e.g. Telco or Enterprise) WebRTC Gateways will often perform basic protocol conversion and media adaptation to ensure that both side can communicate without modification (e.g. converting from SRTP to RTP) However, not all gateways are created equal. Simply delivering SIP to the browser and performing basic media conversion does not make for a quality user or developer experience (especially on mobile). Be sure to find a vendor with equal Web and Telco experience.
- 41. Gateway Evaluation Criteria What is the signaling protocol? How well does it work on mobile connections and what is the impact on battery life? Does it was with both IMS and legacy MSC/CS network? What identity models are supported? Telco only? Is that OK? What codecs are supported? Opus to the endpoints is key for a quality experience. What happens when users close their browser tab? How long does it take the network to realize it’s gone? How are users authenticated? Do they have to log in twice? How are credentials treated in the browser? Are DTLS certificates used to verify identity? What about mobile? How are incoming calls signaled when the app or browser is in the background? And most importantly: how quick can my vendor apply fixes and updates? WebRTC is still evolving but the telco industry can’t afford to sit and wait. Gateway vendors must be able to adapt quickly to web browser changes, regressions and incompatibilities.

- 50. Strategy #1 - Network Exposure This is the most common API approach being taken by carriers The idea is simple: open the network and charge for transactions and usage. The main targets for this model are: • 3rd Party Developers - Long Tail and Enterprise Customers • 2nd Party Developers - Cloud Partners and System Integrators • 1st Party Developer - Internal Teams use APIs to launch services The challenge with this approach is that the focus is on the network instead of users Networks are becoming commoditized. Aligning a strategy around the network does not create incremental value for end users.
- 51. Strategy #2 - User Centric
- 52. Strategy #2 - User Centric Rather that build a platform around the network, start with amazing services and then build a platform / developer ecosystem around your users Model repeatedly proven by Internet companies • Facebook was a website before it was a platform • LinkedIn was a website before it was a platform • Apple set out to build the world’s coolest phone before even considering an App Store Happy users attract developers. Developers and apps attract more users.
- 53. User-Centric Network Effect Users are the operator’s most valuable asset Users represent data and potential customers for developers In other words... users attract developers Ameche enables developers to enhance the mobile experience thereby creating value Value comes in the form of user satisfaction, new users and new revenue Happy users produce more users; which attracts more developers The cycle creates a positive network effect Developer Developer Portal Operator CMO Network Apps Catalog Subscriber Users Attract Developers * AT&T logo used as a placeholder for demonstration purposes
- 54. CRM Integration The Problem The Solution - Integrated Call Logging Sales people forget to log their calls in their CRM When a sales person receives a call, this triggers a look-up using the called number and (e.g. SalesForce.com) resulting in incomplete preferred CRM package. If the number matches one of the clients’ phone numbers, this analytics and missed business opportunities. creates a further trigger to display the calling client’s information. In addition, all communications with clients are recorded and uploaded in real-time to Salesforce.com or the preferred CRM package. Retail Price - $5-7 per user/month © Voxeo Corporation 8

- 56. Social Weaving The Opportunity The Solution - Social Call Activity. Social Caller ID. Social Networking sites like Facebook and With Ameche, operators can weave real-time voice and text conversations into social LinkedIn have changed the way people streams. For example, a service can be created that logs call activity and SMS messages to communicate. the user’s Rather than fight this movement, operators have public or private activity feed on Facebook, allowing then to see all their conversations in an opportunity to integrate the mobile one place. Called you mom on her birthday? You get a ‘good daughter’ badge :-) experience with these services to create brand continuity and stickiness with consumers. Another service could trigger a real-time call Social Caller ID window on LinkedIn with the caller’s profiles and latest activity steam. Ameche makes these types of real-time interaction very simple for operators to deploy using public APIs. © Voxeo Corporation 8
