MSN Messenger
Very large subscriber base (2 x Skype) Protocols use SIP + Proprietary protocols Open Source
MSNDot - Implementation by reverse engineering of protocols
Not complete
Why Portal VoIP threaten Telcos?
Low physical/fiscal barrier for entry Low infrastructure cost Global reach Viral distribution
Huge subscriber base 100M (Skype)-300M (MSN)
Skype subscribers equal the numbers of subscribers in half of Europe
Diversified ways to generate revenue Not limited to VoIP like telcos:
Avatars SMS

Secret Ingredient
Most innovative VoIP services today are a mix of the technologies described below
Secret ingredient? Communication method bridging Community/Sharing/Socializing Quality
Voice Processing
The required voice processing modules for a VoIP applications includes: AEC (AES) – Acoustic Echo Concealment Dynamic Jitter Buffer – has major effect on
quality Connection to sound card / microphone DTMF VAD, Mixer, AGC, NC (NS) Voice quality monitoring CODECs – G711, G729, G723.1, iLBC, GSM
AMR (in mobile related applications)
Voice codecs
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
Signaling - SIP
SIP – Session Initiation Protocol Used to initiate and control VoIP calls
Check security and P2P extensions
Open source implementations SIPFoundry
Signaling - XMPP
Approved standard by the IETF with a vibrant community extending the standard
XML-based protocol <message from=‘yossi@dsp-ip.com’ to=‘a@x.com’> <body>XMPP is easy!</body> </message> Numerous interoperable clients Active Open Source and commercial ecosystem Used by Google
XMPP+ 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
Transport
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
“Secret Ingredient”
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 !!
Skype
Two basic API parts: Skype phone API – connection of devices
such as USB Phones Skype access API – Provide external
applications with an API to control Skype: Create call Terminate call
API C++ Skype4COM - COM API
VB Delphi
Google - LibJingle Signaling
Call Initiation Call Termination Instant Message
Presence On-line Away
Basic Audio coding (PCM) Advantages
Large user base / community No need for “registration” Connection to other application Open Interfaces (JABBER)

“Social VoIP”
Why Social VoIP? High clients acquisition costs
Vonage – 150-200$ according to CEO interview ( link ) Offerings of “VoIP subscriber for sale” 200$ per head (link ) Maybe create a startup for lowering acquisition costs? – exists !
Personalization and Socializing are two key components in creating attraction and stickiness for applications – both exists in social sites (LinkedIn for example)
Some VoIP companies tried to develop their own social networks:
Social Networks and VoIP VoIP Services are appraised by the numbers of
subscribers Social networks has:
Millions of subscribers Data about the connection between Data about the strength of the connection between subscribers
Social networks are a natural partner to VoIP services VoIP-Social network partnership is natural, it provides:
