1 Who, what, where, how? (Actually what, how, who, where)

2  Following the ICT sector for over two decades  Writing for Boardwatch, The Inquirer, VON Magazine (Pulvermedia), TMC  Started HD voice coverage in May 2009  Launch of HD Voice News (HD Connect Now) in August 2009


4  France Telecom deployments ◦ Broadband: Over 500,000 G.722 VoIP endpoints ◦ Mobile: AMR-WB deployed in Moldova  Global Crossing ◦ Built HD conference bridge for customer ◦ Working on open HD conferencing bridge  Verizon Business ◦ Close to 5,000 phones at HQ ◦ Expects early adopters in 2010, general availability in 2011  Cablevision (Optimum Lightwave) ◦ Deployed hosted HD voice service in 2H09

5  Once again, the United States of America is being outclassed by the rest of the world in telecommunications technology….

6  U.S. carriers will wait until the smoke clears and then get a deal because someone else has done the hard R&D…

7  What you get on nearly every POTS (wired or wireless) call today around the world ◦ Ignoring ISDN and the mobile HD deployments…  PSTN grade call = captures3.4 kHz range ◦ 300 Hz to 3400 Hz  Top “range” of human hearing clipped by 2/3  PSTN (POTS) acoustic standards set in 1937 ◦ Since then: FM radio, TV, CD, DVD, HDTV, HD radio…  VoIP equivalent is G.711, 64 kbp/s bandwidth

8  User interface/hardware ◦ Rotary dial to push buttons ◦ Pulse to tone ◦ Corded to cordless ◦ Wired to 4 plug to RJ-11  Plug boards to direct dialing  Network ◦ Crossbar switch to SS7 to IP

9  Also known as “wideband” voice  Range of at least 7 kHz ; i.e. 2x of 3.4 kHz  G.722 codec is the baseline for HD voice: ◦ 30 Hz to 7000 Hz ◦ Still only need 64 kbit/s due to compression  Other HD voice codecs include AMR-WB, SILK, GIPS iSAC.  HD voice only operates on a digital/IP network; POTS can’t handle it!

10  Codec that samples at near full range of human speech ◦ 8 kHz sampling for narrowband ◦ 16 kHz for wideband ◦ 24 kHz for superwideband  Marketing speak for “We’re better than G.722” in many cases  Comes close to delivering “true voice”



13  First third: Narrowband (G.711)  Middle: G.722 HD voice  Finish: “superwideband” in G.722.1C  Biggest clarity jump is from G.711 to G.722  Improvement from G.722 to G.722.1C  Non-native English speaker provides clear example of the benefits of HD voice


15  Better compensation and clarity ◦ Similar-sounding words like "sail" and "fail" garble under narrowband ◦ Acronyms are “notorious” for garbling  End up having to repeat and/or spell out ◦ Narrowband big headache in multilingual setting  Reduction of fatigue - Why conference calls suck ◦ Narrowband clipping means brain plays “fill in the blanks” as a background task ◦ More audio data = less brain strain

16  Codec, software, hardware, network, IP/SIP interoperability  An all-IP (SIP) application  Requires capable speakers & microphones ◦ Analog PSTN can’t be backfitted  Need good QoS, low latency on network ◦ If you can’t do vanilla VoIP, you aren’t going to do HD  For scaling, need agreements to interconnect via SIP for seamless HD calling & transcoding

17  G.722 ◦ Based on G.711, patents expired, now anyone can use it  AMR-WB / G.722.2 ◦ Cellular industry wanted codec based on AMR ◦ Designed to conserve RF usage, 24 kbit/s for HD ◦ Need to pay VoiceAge (and Nokia, FT, Ericsson) for patent use ◦ Currently exclusively in cellular domain, but being pushed for wireline  iSAC ◦ Google BOUGHT GIPS in May for $68 million ◦ Licensed for use by AOL, Yahoo, QQ, Nimbuzz, WebEx, IBM Lotus, Citrix Online ◦ Will Google open source one or more GIPS HD voice & video codecs???  SILK ◦ Skype wanted “superwideband” codec with variable bit-rate adaptability based on CPU and network availability ◦ Royalty-free license, samples between 8 to 24 kHz, use 6 to 40 kbit/s

18  G.722.1 / Polycom “Siren” ◦ Royalty-free usage, not open source. ◦ Bit-rates from 16 to 32 kbit/s ◦ Billions of minutes of usage on Vivex.  Fraunhofer Audio Communication Engine (ACE) ◦ Include specifically designed MPEG codec “AAC Enhanced Low Delay”  “CD quality audio” at “very low coding delays and bitrates” ◦ Pitched for 4G/LTE usage, other parts of toolkit include echo control software, IP streaming stack and error concealment tools. ◦ Why yes, you do have to pay royalties  Speex ◦ Open source patent-free ◦ Sampling from narrowband (8 kHz) to wideband and ultrawideband ◦ Can use bitrates from 2 to 44 kbit/s  Broadcom BroadVoice ◦ Offered royalty-free and open source under GNU (C, floating & fixed, GNU LGPL 2.1) ◦ Wideband at 16 kHz sampling, 32 kbit/s, narrowband 8 kHz sampling, 16 kbit/s

19  Developers ◦ Programmers all think they can write something better.  Hardware designers ◦ Simpler is better, fewer codecs, less expense to test and support ◦ On device side, less processing = longer battery life  Wireless crowd ◦ Lean on the device CPU to compress (AMR-WB, SILK) ◦ Old guard: Every little RF bandwidth is sacred  This goes out the door with 3G/4G!! 64 kbp/s is zippy!  Said with a straight face as carriers intro streaming video, two-way conferencing…yah, WTF  Network core ◦ More codecs, more transcoding between formats ◦ Service providers want to avoid transcoding as it costs $$ & has lose some HD voice goodness in translation between HD codecs  Cable companies, FT love CAT-iq for end-to-end G.722

20  Soft clients ◦ Plenty floating around supporting G.722, iSAC. One big one supporting SILK  Hardware ◦ Desktop handsets  Vast majority supporting G.722, some SILK, AMR-WB creeping in  Need good acoustics – speakers and microphones ◦ Mobile handsets/devices  Need good acoustics  Dual mics in vogue for echo/noise cancellation

21  Simple case: Same codec type ◦ On same LAN/network – No sweat ◦ Beyond WAN/firewall - Interconnection via SIP  Different codec types – Transcoding ◦ HD voice to PSTN/G.711/G.729  PSTN not going away; carriers understand  But if you have to touch the PSTN, HD goodness goes away as you downshift to narrowband ◦ G.722 to AMR-WB, SILK, iSAC  Service providers annoyed, but accept eventual need to transcode between codecs (G.722/AMR-WB big one)

22  To scale, everyone has to interconnect via SIP for seamless end-to-end HD calls calls  Service providers don’t do SIP peering/interconnect/federations out of the box- ◦ Security considerations (SPIT, DDoS, you name it) ◦ ENUM is overhead ◦ Quality of Service ◦ Settlements & least-cost routing (i.e. who gets cash)  As a result, there are many HD voice islands: ◦ In enterprises ◦ At service providers

23  Can peer (direct relationship) ◦ Service provider to service provider  Interconnection (Federation) service ◦ Spoke and hub network with hub service managing ENUM, technical, business, and legal issues  Interconnect automagically via Cisco IME

24  Xconnect ( Global ◦ HD voice trial 2Q10 (i.e. NOW)… still going on. ◦ Needs to make a clear value proposition  Small universe, service providers don’t want to pay  Sprint PIN (Partner Interexchange Network) ◦ Currently vanilla VoIP, but capable of bigger things ◦ Handles price on per-minute cost for now ◦ Architecture can handle full range of rich media (voice, HD, video), but managers still wrestling with concept beyond simple VoIP.

25  BYPASSES hub/spoke & service provider mediation  Appliance handles virtualized peer-to-peer connections  Currently only works with Cisco products; hopes proposed IETF standards proliferate to others  Gen 1 box “manages” up to 10,000 or up to 40,000 phone numbers/devices – designed for large enterprises  Each IME publishes phone numbers to dynamic hash table capable of handling up to 10 billion entries.  After first “shared secret” PSTN call, IMEs conduct authentication process and exchange security particulars  Subsequent calls routed on “virtual SIP trunk” and can be vanilla VoIP, HD voice, video or anything else SIP.  One creator of ViPR & IME former Skype employee, so you can see where the peer-to-peer comes through.

26  Layer 8 – Money ◦ Voice providers used to termination, per-minute LD ◦ Flat rate makes old telcos tilt a little ◦ Service providers reluctant to pay $$$ for currently small universe of HD calls ◦ Verizon Business providing free SIP calls in VIPER VoIP service to its customers  Layer 9 – Politics ◦ Lot of jockeying by smaller players for peering ◦ Larger players moving slowly to IP interconnect  Cable companies will likely do this next year

27  Conferencing the “Killer App” ◦ Clarity, less stress, identify voices, accents less of a barrier  Multi-national conversations for bonus dollars ◦ Non-native speakers of language can  Be understood better  Better understanding of what is being said  Transcription (i.e. voice to email) ◦ Computer-based fewer errors ◦ Human, same thing, easier, less replaying

28  Better IVR/anything processing voice  Young and old ◦ Young (under 3) have squeaky voice, don’t understand on a phone call ◦ Old, don’t hear so well; HD adds back some clue  Public safety/national defense ◦ Better 911 calling ◦ Better translation/understanding of intercept  Yes, we want the enemy to have the latest tech…

29  Major Telecom Carriers  Mobile Carriers  Cable/MSO  Hosted VoIP/Business VoIP  Consumer bypass play  By region: ◦ Europe now ◦ Asia beginning ◦ North America “under the radar.”

30  France Telecom ◦ At least 500,000 users/end-points on broadband  Verizon ◦ Internally - nearly 5,000 endpoints installed at NJ HQ ◦ Verizon Business - “Early adopters 2010, general availability 2011”  VIPER (VoIP enterprise service) will support G.722 by end of 2010  BT ◦ BT Hub, around 2 million G.722 capable end points deployed  Telstra ◦ Hosted HD service for businesses; up to 11,000 end-points internally  Global Crossing ◦ Running HD conferencing bridge for top-tier customer ◦ Public HD conferencing bridge coming  Others rumored: Telecom Italia, Nordic telcos, AT&T ◦ Often repeated, but never verified

31  France Telecom / Orange ◦ Moldova, Armenia (!) running today ◦ France “by end of July” NOW ◦ UK trials done, rollout “later this summer”/3Q ◦ Belgium, Luxembourg, Spain in 2010; bet on Tunisia  SFR ◦ Testing in France now, service up by fall  3 UK ◦ Demo, teased media in 2010  Deutsche Telekom (DT) ◦ Has trialed HD on LTE  “3G+”, VoLGA and 4G expected to be drivers

32  CableLabs has issued multiple standards relating to HD Voice ◦ DECT CAT-iq in 2009, 2.0 standard in June  End-to-end G.722 call, with DECT 6.0 wireless at end-user  CPE with embedded CAT-iq starting to come in pipeline ◦ IP Interconnection standard released in June has ENUM defined  Cablevision/Optimum Lightpath hosted HD service now  Cox -“2011” is latest word.  Comcast ◦ The Cable Show 2010, CTO said “As we move to HD voice…”  Time-Warner Cable - Has tested HD voice, coy on deployment plans ◦ Expects CPE to be capable “within 5 years…”  For all cable, enterprise drive HD ◦ SIP trunking, Hosted

33  Many independent hosted providers ◦ Differentiator against bigger players  8x8 biggest in North America ◦ Aastra Hi-Q upgrade ◦ 70,000+ end-points (Jan 2010)  Numerous players w/2,500 to 7,500 end-points.  Lot of talk among smaller guys for direct peering ◦ IP Peering Alliance  Independent hosting business VoIP service providers ◦ Cloud Communications Alliance  Smaller group 8 in IP Peering Alliance talk more formal

34  Ooma -Hardware/service bundle ◦ Second-generation Telo hardware can support G.722 & CAT-iq ◦ 4Q 2009 shipped 25,000 units ◦ Do the math, conservatively ship around 100K+ units in 2010 ◦ BUT, ooma took a left turn; now about narrowband VoIP quality  WorldGate ◦ Guys who did the OjO phone ◦ Two year, 300,000 unit deal to ship videophones to ACN; the phone supports G.722 as well as video.  Vivox ◦ Provides voice via Siren 14 (G.722.1C) to MMORPGs & Second Life ◦ 16 million users, Over 2 billion minutes per month ◦ Customers include CCP Games, Electronic Arts, Gaia Online, Icarus Studios, Linden Lab, NCsoft, Realtime Worlds, Sony Online Entertainment and Wizards of the Coast.

35  Europe ◦ FT leading, others joining.  Asia ◦ Australia/Telstra offering hosted service ◦ Korea, Japan offering services; hard to tell what  North America ◦ “Under the radar” with earlier adopters in enterprise, consumer, cable, and hosted VoIP.  Africa, South America ◦ Good potential in greenfield 3G/3G+ projects

36  Service provider attraction/retention  Conferencing  Multi-national  As a part of a UC play  Higher education

37  Attraction ◦ Better quality voice than narrowband, other carriers  Retention ◦ Better quality product keeps people from switching (i.e. keep churn down) ◦ France Telecom not charging extra for bband HD  Differentiation ◦ Set apart from everyone else… until everyone else gets it  Monetization ◦ Pay for better quality (?) Nobody knows  Pre-pay vs post-pay interesting to watch

38  Clearer communication ◦ Don’t have to repeat acronyms  Less stressful ◦ People focus on content, not figuring out what is being said  Can identify individual voices easier

39  BIG winner for Fortune 500/international businesses  Non-native speakers can understand what is being said better/easier ◦ Clearer speech, no clipping of similar sounds, don’t have to guess/interpret  Can understand non-native speakers better ◦ Accents much less of a factor because there’s no clipping.

40  Rolled in as “yet another feature” in a UC play  Better voice quality provides ◦ Clearer voice mail messaging ◦ More effective transcriptions  Voice to email  Less human work/intervention in voice-based work products (Health care, legal, financial) ◦ Cablevision/Optimum Lightpath’s play in NY

41  Desire to work with “leading edge”  Large campus deployments  Deployments of 5,000 (and more) end-points ◦ Penn State ◦ Texas Tech

42  Service Providers ◦ BT, Cablevision, France Telecom, Verizon Business, 8x8  IP desktop handset manufacturers – ALL of them ◦ Aastra, AudioCodes, Avaya, Cisco, Polycom  Mobile handset manufacturers ◦ Nokia, Sony Ericsson declared, others in pipeline  Network core Aculab, Cisco, Dialogic,Ericsson  Applications ◦ BroadSoft, CommuniGate, Unisys, WYDEVoice

43  Macro picture of HD voice  Mobile HD voice progression  Broadband

44  Today ◦ Technology available in abundance ◦ Lots of HD islands  Near-term ◦ IP interconnection is coming  Hurdle is getting past Layers 8 & 9 (money * politics)  Longer-term ◦ Superwideband become a codec/CPE upgrade  If people want it…

45  Mobile HD voice to happen faster ◦ Typical handset lifecycle of 3 years ◦ Arms race (more features) and Moore’s Law (faster/cheaper silicon) aid process  France Telecom taking lead role in Europe ◦ Bringing handset manufacturers in  Expects full portfolio to be AMR-WB capable by end of 2011  Competitors (SFR) starting to match in Europe  Asia – likely Japan, Korea ◦ Info hard to come by; anyone have a source?  North America – Roll some dice… ◦ Qualcomm pushing CDMA-based solution with its non- standard codec

46  Europe ◦ Orange and BT biggest deployments ◦ Virgin likely, Norway and Holland also cited as working on it ◦ Look for “superwideband” to happen first in Europe  U.S. – Verizon/AT&T vs. Cable Companies ◦ Cable appears to be on a path for GA in 2011-2012  Approved DECT CAT-iq 2.0, ENUM in June 2010  CPE gear starting to come out in 2010 ◦ Once one side comes in, others expected in “avalanche.”  Asia ◦ Korea, Japan

47   TMC ( has a HD voice “Channel” with  – Graves on SOHO ◦ The guy who provided the YouTube demo clips  also has some HD voice info, demos
