  1. A Brief History of VoIP Jonathan Christensen GM Audio Video

  2. A long time ago…….. 1996-2001

  3. 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

  4. Class 5 Switch Class 5 Switch Tandem Switch TDM Tandem Switch

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

  6. 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..

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

  8. 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

  9. 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”

  10. What Do Consumers Get?

  11. Great Savings? Really? And New Features?

  12. 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

  13. The Summer Revolution - 2003

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

  15. 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

  16. 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..

  17. What’s Next?

  18. 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..

  19. 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)
