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

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

Mis-navigation: Callers get confused by
prompts or “zero-out”. Leads to wasted agent time.

Working toensure a quality VoIP system
•choosing the correct speech codec, •the impact of latency, •jitter buffer design
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!Yes – finally!

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
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
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
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 3rd party developers
OS SDKs compared
“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
