  1. Voice SMS Merging VoIP & Mobile to Create A Compelling Service Brough Turner, SVP & CTO, NMS Communications

  2. Why should I care? • Voice short message service (SMS) is a highly successful new service • Leading solutions built on NMS technology • Broad lessons for any new mobile service

  3. *0* ERIC LEE 28/08/05 23:30 Hi, I Have sent U a BUBBLE dial *0* to hear it (FREE) *0* What is Voice SMS? • Similar to SMS text messages, except with voice • Sender records a short voice message • Recipient gets a text alert: “You have a Voice SMS from … ” • Recipient clicks and hears the voice message Source: Bubble Motion Pte Ltd

  4. Not “Multi-Media Messaging” • MMS a fully specified 3G service • Includes voice messaging • Ovum forecasts US$3.8B in 2005; $13.8B in 2010 • $2.9B to $9.5B picture mail (all kinds – MMS & otherwise) • $0.8B to $3.8B video messages • $94M to $496M audio messages • But MMS slow to take off • Awaiting ubiquitous handset support and interoperability • MMS-based “Voice SMS” also starting slowly • Example: Sprint’s “Voice SMS” in US – only MMS handsets can send messages, few deployed, few messages sent

  5. Voice SMS Unique Advantages • Over text messages • Easier to use • Voice conveys more emotion • Don’t have to be literate • Versus Push-to-Talk • Works when recipient is unavailable • Good when you just want a message, not live conversation • Compared with voice mail • Easier, more immediate; not a live conversation • Compared with MMS • Works with any handset, any network (2G, 2.5G, 3G)

  6. Subscriber Benefits • New, highly personal way to communicate • Costs less than a voice call • Easy to use • Overcomes text usability issues • Available in all languages • Does not require literacy • Works with current handset • Send messages to any handset

  7. Operator Benefits • No handset software — target entire subscriber base • Application overlay — no changes to existing infrastructure, works on 2G, 2.5G, and 3G • No capital investment; extremely rapid deployment • Little customer education • Popular — rapidly adopted • Commands 50 to 100 percent premium over SMS • Proven money maker

  8. Advertising Jokes Premium content: Celebrity messages Audio clips Ask an expert Voice alerts: Sports News Weather Voice Reply to Text Voice Blogs Dating Voice information services Ringtones Ringback tones Contests International Voice SMS New Voice SMS Revenues

  9. Voice SMS History • Ideas date back at least a decade • Jan. 2005: Digi (Malaysia) launches “BubbleTalk” by Bubble Motion • Sept. 2005: GrameenPhone (Bangladesh) launches “Voice SMS” by Kirusa • Widely adopted today: • Over a dozen vendors with announced platforms • 15+ networks offer Voice SMS service • >300 million mobile subs have access

  10. Digi (Malaysia) Case Study • GSM network with 5.6 M subscribers (9/2006) • Bubble Talk launched late January 2005 • Two month promotion: subscribers offered 10 free messages per day • 50 percent premium over text messages • Greater than 35% penetration in six months • Over 200,000 messages per day by 8/2005 • All other operators in Malaysia forced to react within first year

  11. #1 mobile operator in Bangladesh • 5 M subscribers (9/05) to 10 M subs (11/06) • Voice SMS launched September 2005 • Based on Kirusa platform • Supported with newspaper & TV advertising • Priced 25%-66% over text messages • Rapid adoption • 6% first week; 16% first month • Over 40% (3.6 million users) by August 2006

  12. How does it work? • Dial short code & then normal mobile number • Typical handsets support prefixing numbers in your contacts directory • Prefix causes call to be routed to IVR system • IVR receives call with caller & called numbers • Beep, record message (& optionally other options) • Bill caller • Send SMS to called party saying“You have a Voice SMS from <calling party>. Press green “send” key to hear your message. <IVR system phone number embedded here> ”

  13. Receiving a Voice SMS • Called party receives text message • Presses green or “send” key • Phone dials IVR system • IVR system sees caller ID, looks up messages for that party • IVR plays message(s) immediately • No prompts or dialog required • At end, offer options • “To listen again press one, to reply press two, otherwise just hang up”

  14. Billing System Issues • One Voice SMS needs two voice calls! • Price point needs to be more than text SMS but less than a voice call • “Cost” not an issue except during busy hour • Focus is maximizing revenue! • All billing systems support special billing numbers (premium rate and free numbers) • IVR assigned short code or other special number

  15. Not Restricted to Operators • Mobile network integration • Facilitates recruiting and enrolling subscribers • Dial codes facilitate sending messages • Not essential • Only need PSTN voice and SMS connectivity • US example: Pinger • PSTN & SMS connectivity purchased wholesale • Speech technology overcomes lack of dial codes • Import friends names/numbers to Pinger • Dial Pinger • Speak name of person to receive Voice SMS

  18. Any Handset, Any Network • A prime application success model • Worth consideration by any application developer • Don’t need critical mass for service to take off • No wait for “network effects” • Other services with comparable characteristics: • Voice mail — takes messages from any caller • Ringback — ringback tones heard by all callers

  19. Conclusions • Winning Applications • Ideal: work with any handset, any network • If not: provide bridge – partial functionality with any handset • NMS Vision VoiceXML Server • Complete deployment platform for Voice and Video applications (VoIP or PSTN) • Carrier grade Signaling Services (SIP, SS7, ISUP, ISDN) • VoiceXML extension APIs for outbound dialing, authorization, and SMS voice messaging
