VoIP Technology To Business Models 2

Yossi Cohen DSP-IP

Voice Quality , Automatic NAT/FW traversal AEC, AGC, VAD, CODEC, GSM AMR, SIP, Jabber…. Making it all work on mobile

Most innovative VoIP services today are
a mix of the technologies described below
Secret ingredient?
Communication method bridging
Community/Sharing/Socializing
Quality
Wireless Technologies Voice Processing Transport NAT/FW P2P Jabber /XMPP SIP/Simple Secret Ingredient

In mobile it just get more complicated
Device & OS fragmentation :Symbian, Windows Mobile, Brew, J2ME, iPhone, Blackberry….
Symbian:
UIQ or S60 or S80 or ...
Battery / Power issues
Processing power of a toaster in some devices
VoIP over WLAN has larger Jitter and Packet loss

Instead of going to the garage for three years to re-invent the wheel: buy, outsource and integrate
Component level
voice processing
SIP / Jabber + NAT/FW traversal
Complete solution
Complete soft-phone over whatever platform
Concentrate on
building user base
Making buzz
Product features

Old Business Models & Their problems

Equipment vendors – Sell VoIP Equipment
VoIP Service Provider – Sell VoIP Service
VoIP Termination & Billing
VoIP Reseller Platforms
… .

Equipment Vendors Examples
VocalTec, VCON
Problems
Diminishing margins on equipment
Copied easily
Mind Set
How to Improve our EQUIPMENT
Goals: Add the new codec, lower BOM costs
The right Mindset
How to make it a better SERVICE – take it to the internet (WebEX)

Example - Vonage
Revenues - VoIP subscription fees are:
None or Very low per minute rates/ low flat rate
Client Acquisition Costs - high
Vonage–150-200$ according to CEO interview
Offerings of “subscriber for sale” 200$ per head
Churn - high
No Differentiation: client on a 19.99 flat package will turn to a different vendor for 18.99

Examples
DeltaThree – VoIP Platform For MSN
Net2Phone – VoIP Platform for Yahoo!
Problems
No Real technology / Differentiation
Competition
Q: Who's Doing “VoIP Platform” for Yahoo! today?

PC Based VoIP Mobile / Roaming Solutions

A Leading VC is looking for the next VoIP Monster.

Portals & IM Companies Social Networks Device Vendors

Compare to Middleware Market

Microsoft
Google
AOL

Wideband codecs (8KHz VoIP)
GSM AMR WB – G722.1
iSAC 10-30KB
iPCM-WB – 80KB
Siren 7 – Polycom
UltraWideband Codecs (14KHz Voice)
Siren 14 – Polycom
Other open source codecs
Speex – Part of XIPH Project

SIP – Session Initiation Protocol
Used to initiate and control VoIP calls
Check security and P2P extensions
Open source implementations
SIPFoundry

Approved standard by the IETF with a
vibrant community extending the standard
XML-based protocol

<body>XMPP is easy!</body>
</message>
Numerous interoperable clients
Active Open Source and commercial ecosystem
Used by Google

Jingle
– Defines way for XMPP clients to exchange rich media.
– Audio is furthest along, but also work in progress for Video.
app sharing, etc.
Audio already in use by Google Talk .
– Makes it easy to work with SIP.
HTTP Binding
– XMPP over HTTP
– embed messaging and presence into any web page
with Javascript and Ajax.
– Possible Jingle integration for rich media in web pages? Perhaps using Flash ?
Personal Event PubSub (PEP)
– Share rich presence data like geo-location.
– Model to decide who to send what presence data to
- Connection to “Twitter”-like services

RTP – a simple real-time transport protocol
SRTP – Secure variant (exists in open source)
cRTP – Compressed headers version of RTP
NAT and Firewall traversal are key components in most VoIP applications
Several NAT traversal protocols exists:
STUN – scalable partial solution
TURN – less scalable complete solution
ICE – uses STUN or Turn
Several techniques for Firewall traversal
Usage of TCP/IP lowers voice quality

VoIP Quality – Skype example
Today “Skype better quality” is not an advantage but
a standard for VoIP applications
VoIP over WLAN
First Applications of VoIP over cellular, FMC
Video - PC
Skype as a pioneer again : VP7 video codec, not that important
NGN video IM - ooVoo
Avatars
Connection to CyWorld , SecondLife , social communities
Look at COMBots !!
