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

• Adding Fonolo to your site

When a visitor clicksa call button, Fonolo will
connect her to the right spot in your phone system

Caller
Only one line of HTML to add. You can assign
different parts of your phone menu to shortcut
buttons.
Your phone system
Fonolo extracts the text in your prompts and
automatically stays synchronized with any changes
in your IVR.

Billingagents
Lack of Feedback Current approaches are
expensive or time consuming.
Poor experience Phone menus make callers
frustrated.
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

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!

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

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
  ATT users upgrading)
• Iphone users give ATT 94.5 ARPU compared to avg
  of 60
• Power to 3rd party developers

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 (Palms 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
