Ten Years

Jonathan Christensen GM Audio Video A Brief History of VoIP

A long time ago…….. 1996-2001

The Pioneers
Vocaltec’s Internet Phone
Gateways: Clarent, NetSpeak, Nuera, Vocaltec, Sonus… Cisco
The Carriers: DeltaThree, ITXC, Level3
New breed of internet Codecs - wideband
The use cases gel:
End users: PC-PC “Ham radio” scenarios
Carriers: site to site “tandem” trunking
Some “mainstream” apps emerge
NetMeeting (last updated in 1999 and still in action)
2 Stage dialing: 1 800 CALL-ATT

Tandem Switch Tandem Switch TDM Class 5 Switch Class 5 Switch

VoIP Death of Distance Class 5 Switch TDM-IP Gateway Class 5 Switch TDM-IP Gateway

Tandem Trunking
Bandwidth efficiency (more compression, statistical multiplexing)
LEC - Avoid the expensive long haul lines
Incumbent LD providers could avoid termination fees at the local off-ramp because the trunk is IP..
Its an unregulated “information service”..
Arbitrage, arbitrage, arbitrage
Oh yeah.. And inferior service..
Sometimes offered under “alternative” brands..

Moving on.. 2001 Pulver, Vonage, and Consumer VoIP

Consumer VoIP
Pulver’s early inspiration
Min-X, the IP voice minute exchange
Free World Dialup (one port gateway)
Komodo and the first ATA
Turns any perfectly good phone into an inferior IP handset
Cisco acquires Komodo and validates the market
Vonage is born…
Voice over Broadband begins

VoBB Changes the Players / Power Structure….
Independent Vonage sets the pace early (with lots of cash)
Long distance players enter local service markets…
The MSOs respond -- with more Buzzwords and TLAs:
“ Triple Play” “NGN” “IMS” and the dreaded “Quadruple Play”

What Do Consumers Get?

Great Savings? Really? And New Features?

Another Foot in the Grave…
Beginning of the end?
Incumbents match prices and features on TDM
Land line telephony is cheap.. Still... Losing to mobile..
Commoditization is complete
VoIP “export” networks are the biggest innovation
Send your ATA to India..
Location independent (death of distance – again)
Smashing the geocentric numbering plan
Further deteriorating the old voice business

The Summer Revolution - 2003

IM (therefore IP) IM VoIP Video Visual Sharing Rich Communications

The Summer of Skype
The stage was set.. The solution was 99% complete
Robust IP audio stack
Multimedia PCs
Broadband penetration
P2P file sharing networks running at internet scale
NAT traversal techniques
IM networks..
Skype simply closed the loop..
One application with the right formula
Users loved it.. Industry was confounded..
By fall VoN there were 500K downloads

276 Million Users Can’t Be Wrong
Global appeal / reach
Reliable PSTN interconnect
Multitude of device options (PSP, N800, Cordless..)
Profitable ..
Enter the era of rich [PC based] Internet communications
Multi-modal communications (original SIP vision)
Real time video, Data, Presence, Text, Wideband Audio
Smart endpoints, open platform…
Application innovation..

What’s Next?

Sorting the Mobile Mess
Mobility is the last anchor to the old way
Fastest growth telecom service today
Spectrum scarcity makes it a perfect walled garden
The good old days again
Closed networks.. Device lock-in.. Phone numbers with geographic bias.. Contracts.. YUCK !!
Finally.. The Internet goes mobile
First successful auction - 22 MHz of “700 band” spectrum
“Open Platform” conditions apply
A new game begins..

The next 10 years
The Era of Rich Mobile Internet Communications
Multi-modal communications (original SIP vision)
Real time HD video, Data, Presence, Text, Wideband Audio
Smart endpoints, open platform… Application innovation..
Fixed / Mobile Convergence – for real…
Mash ups of web based communications
Freedom with mobility…
Natural segmentation of competencies
Network infrastructure (pipes)
Application innovation (developers)
