4. Components Developing a mobile VoIP application that rivals PSTN and mobile phone quality.

5. 5 Mapping Phone Space  Just like Google spiders web space, we spider phone space  Currently maintaining a live map of phone menus for over 500 companies in North America.  No cooperation from those companies required

6. 6 When a visitor clicks a call button, Fonolo will connect her to the right spot in your phone system Fonolo maps out your phone menu Adding Fonolo to your site Agent Embed the widget on your site http://www.yoursite.com Caller Your phone system Fonolo extracts the text in your prompts and automatically stays synchronized with any changes in your IVR. Only one line of HTML to add. You can assign different parts of your phone menu to shortcut buttons. 1 Ring 23

7. 7 Lack of Feedback: Current approaches are expensive or time consuming. Company IVR System Poor experience: Phone menus make callers frustrated. Problems addressed by Fonolo Tech support agents Billing agents Company Management Mis-navigation: Callers get confused by prompts or “zero-out”. Leads to wasted agent time. ?

8. Working to ensure a quality VoIP system choosing the correct speech codec, the impact of latency, jitter buffer design choosing the correct speech codec, the impact of latency, jitter buffer design

9. Better than PSTN VoIP allows for better than PSTN/mobile experience – HD voice can lead to greater intelligibility, comfort and improved end-user experience Yes – finally!

11. Impact of IP Networks While HD voice important, need to account for network impairments as important – Wireless networks particularly challenging – Need for rapidly adapting jitter buffer and smooth packet loss concealment

12. Mobile platforms inherently challenging Low complexity solution to maximize limited processing power and battery Noise suppression to handle excessive background noise Hands Free operation requires acoustic echo cancellation Small display and camera placement issues for video

13. The Game Changers The iphone OS and Android OS have changed the communications landscape, their inherent challenges and what it means for application developers building solutions for mobile unified communications

14. The biggest game changer Why ? It proved: – UI matters – OEMs can demand operator revenue pie – Customers care about the phone, not just service In Q408, ATT added 2.1m new subscribers, out of which 36% were NEW iphone subscribers (not old AT&T users upgrading) Iphone users give AT&T $94.5 ARPU compared to avg of $60 – Power to 3 rd party developers

15. OS SDKs compared

16. “Web” programming mobile tools Concept: – Building apps for mobile phones is complex. Different languages, UI, etc. Solution: – Build using HTML, CSS, Javascript. Key Players: – PhoneGap, RhoMobile, Mojo SDK (Palm’s Web OS) How: – App developer writes code in HTML/CSS/JS/Ruby etc. – Headless browser is instantiated – Browser renders UI – Browser executes JS – JS hooks & URI hooks for plugins Advantages – Consistent, predictable, scalable UI (limited by browser capabilities) – Fast development Disadvantages – Generally slower, does not work with all browsers/phone platforms, still nascent technology wrt stability – Not good for realtime graphics/heavy apps
