VoIP Today: VoIP is Maturing
• Consumer Penetration– 4.46B Skype minutes used, 58M downloads
– > 1.3M paying VoIP subscribers (Vonage, Skype, CableVision)
• Enterprise penetration (IP Centrex/PBX).– Incumbents upgrading their solutions to support IP (SIP)
• Cisco, Nortel, Avaya all moving towards IP PBX support
• 2004 IP PBX new lines surpassed PBX new lines
– Broadsoft, Sylantro, Vocal Data, Centile emerging for IP Centrex.
– Recent major announcements from large enterprises (e.g. Bank of America, Ford)
• Carrier Penetration
– Class 4 trunking solutions very mature
• Pros: – Cost (cheaper than cellular), coverage (leverage existing broadband
infrastructure so no new towers, BTS, BSC, etc. required), usage (~40% of calls made could be done using broadband)
• Cons:
– Internet (unaffiliated networks), WiFi QoS
CDG VoIP Summit, 8 Feb. 2005 9
VoIP Today: Trends
• Broadband is up to 27M in 2003
– 46% Year over Year
– Europe and APAC lead US in broadband reach
• VoIP is growing fast
– 1 million in 2004; up from 131K in 2003
– MobileVoIP is a sector event
– Interest across all major service provider groups
– Competitive threats exist
• It’s happening. Now

VoIP Today: Opportunities
• Broadband / Mobile penetration
– Broadband and Mobile penetration high
– Broadband passes the majority of residences and businesses
• Bundling
– Mobile voice is the lead application
– Subscribers shop for the best bundle
– Bundles want a VoIP offer
• Client/Device alternatives
– It’s about the identity, not the device
– It’s about anywhere, anyplace communication, not the device
– It’s about using best device at the moment

Mobile and VoIP Working Together: What
• Standardize basic functionality between networks– Interwork non-mobile devices
– Automatic network selection
– Seamless roaming
– Active call handover• Broadband VoIP <-> CDMA CS
• Broadband VoIP <-> CDMA VoIP
• Identify network impacts on applications– Broadband is faster, but QoS can vary
– Applications may need awareness of network switch-over• Example: Defer handover if it would disrupt an application?
• Work towards “voice is a data application” paradigm– Much better service interaction when voice is no different from
other data applications
CDG VoIP Summit, 8 Feb. 2005 18
• Intelligent Devices - Specify Standards– Service providers can specify devices
– Network selection, roaming, handover, authentication, etc.
• Intelligent Networks - Specify Standards– Authentication, billing, enforcement, provisioning, security
– Access independent services
– Seamless roaming and handover between access networks
– MMD/IMS services for today and tomorrow
• Intelligent Services – Interconnect Service Providers– Operator owned
– Enterprise owned
– ASP owned
• MobileIGNITE - Industry Collaboration– IOT and service definition/refinement
– Open standards, robust and varied service interconnection
– Develop approach for emergency calling – particularly robust location detection

• start small on existing networks
• grid architecture lowers cost to scale
• basic voice extended over IP access networks is the killer app
• mass adoption rapidly

• Multiple channels to end users
– Mobile carriers, cable MSOs, DSL providers, ISPs, WISPs, independent VoIP carriers, Verisign
• Architecture applies to GSM as well as CDMA
• Dual device scenarios – volume market sooner than dual mode phones
• MMD/IMS alignment enables migration from legacy MSC
– IP to IP calls, and IP to PSTN calls do not require MSC
– Backhaul efficiency using IP not A-interface
– Results in cost advantage enabling price competition head to head with PSTN
• SIP based
– Enterprise IP PBX interworking
– IP Centrex compatible
– Wireline IP telephony compatible
• Centrally host-able for roaming & clearing (e.g. Verisign)
• Nomadicity: leveraging better QoS for applications
• Leverage existing media gateway/softswitch investments
MobileVoIP = Service Provider Options
