  1. Developing IP Phones Karen Hong Director, Product Marketing 8x8 Inc.

  2. Residential Broadband VoIP Market 42% North American Market Voice over Broadband Penetration 34% 25% 16% 7% 1% Source: Gartner

  3. POTS POTS Target Applications: Residential ATA AND AP Can be integrated today with WLAN WiFi card Softphone ATA Videophone Packet Phone Adapter VoWi-Fi 10/100BaseT Broadband IAD IP Phone DSL or Cable Modem 10/100BaseT WAN Internet 10/100BaseT 10/100BaseT AP / Router / Gateway ATA+5.8Ghz cordless

  4. Residential VoIP Product Segmentation • Current Market Segmentation for Residential VoIP End Points • IP Phones/Phone Adapters (Terminal Adapters): • Basic interface device converting analog phone traffic to IP based traffic; a voice only device with no data capability • Residential Voice Gateway (RVG): • Standalone voice appliance converting analog phone traffic to IP based traffic AND data routing for home PC connectivity in a single device • Integrated Access Device (IAD): • Integrated voice/data/broadband modem solution collapsed into a single standalone unit • VoWLAN (Wifi-phone) • Integrated voice/data/broadband modem solution collapsed into a single standalone unit

  5. IP Phones/TAs Key Features • IP Phones/Phone Adapters (Terminal Adapters): • 1 to 2 RJ11 ports for phone termination • 1 Ethernet port for interfacing to Broadband Modem or router • Supplementary Service Support • SIP • Telephony only features • Low-End Solution • Optimized for low cost • Complete voice feature requirements but no data features • Key Features • Voice Processing: G711, G729ab, G723.1, Echo Cancellation, Tone processing, T.38 fax, etc • SIP protocol, provisioning • Typical Positioning • Lowest cost device for IP residential telephony (ignoring the PC only, peer to peer services) • 1st phase of service provider subscriber offering • Relatively mature market

  6. Residential Voice Gateway Key Features • Residential Voice Gateway (RVG): • 2 RJ11 ports for phone termination • 2 Ethernet ports: 1 for interfacing to Broadband Modem, 1 for PC or router • Supplementary Service Support • SIP • Telephony • Data (Routing/Firewall/NAT) • WLAN option • Multiple Ethernet ports • WAN connection to an external cable or DSL modem • Single or multiple LAN connections direct to PCs or to home router • WLAN AP Option • Key Features • Voice Processing: G711, G729ab, G723.1, Echo Cancellation, Tone processing, T.38 fax, etc • SIP protocol • Service Provider provisioning • Data/Voice routing, firewall, NAT, DHCP, etc. • Typical Positioning • Low cost device for IP residential telephony • Largest segment of current RGW market deployment with rapid growth • Routing/Data features require networking and voice expertise • Service providers quickly moving to WLAN solutions

  7. Integrated Access Devices Key Features • Integrated Access Devices (IAD): • 2 FXS ports for phone termination • 1 Ethernet port for PC or router • DSL or Cable modem interface for WAN • Supplementary Service Support • SIP • Telephony • Data (Routing/Firewall/NAT) • Broadband Modem functionality • WLAN option • WAN/Broadband Access • Integrated cable or DSL modem • LAN Ethernet Interface • Single or multiple wired ports • Optional wireless access point • Key Features • Voice Processing: G711, G729ab, G723.1, G729e and G728 for PacketCable, Echo Cancellation, Tone processing, T.38 fax, etc • SIP or MGCP protocol • MSO/Service Provider provisioning • Optional voice/data routing • Typical Positioning • New Broadband subscriber deployment • Driven by cable companies and DSL service providers • Routing/Data features require networking and voice expertise • Service providers quickly moving to WLAN solutions

  8. VoWLAN Phone Key Features • VoWLAN (Wifi-phone): • Low-cost phone which utilizes the WLAN and VoIP infrastructure –not a GSM/CDMA handset or cellular-WLAN combo phone • Significant market interest in potential applications • mobility for traditional vertical markets • mobility for enterprise desktop and residential / DECT or cordless phone replacement • Solutions in the market today are limited (Spectralink, Symbol), proprietary and expensive – limited to niche vertical markets • Significant barriers to adoption exist: • cost must be comparable to DECT / cordless phones • low power consumption – minimum 4 hour talk time, 80 hour stand-by time • Standards – 802.11e (EDCF), 802.11i (WEP, TKIP, AES) • Targeted integrated silicon solutions are needed – Broadcom, Agere, TI, etc… SpectraLink

  9. Residential VoIP Product Evolution • IP Phone/Phone Adapter (Terminal Adapters) • Full Voice Features (Supplementary Services, Provisioning, FAX, full vocoder support, etc…) • Video • Residential Voice Gateway (RVG) = Phone Adapter + • DECT or 5.8Ghz cordless phones • Routing/Firewall/NAT • PC interface • WLAN option • Video • Integrated Access Device (IAD) = Residential Voice Gateway + • Broadband Modem (DSL/Cable) Functionality • VoWLAN (Wifi-phone) • GSM/CDMA wireless • Smartphone concept • Video

  10. Quality of Service • Network Performance Management • Audio and Video Codec • Audio: G.729, G.711, G.722, iLBC, G.723.1 • Video: H.263, H.264, MPEG4 • Acoustic Echo Cancellation • Jitter Buffer Control Management • Packet Prioritization

  11. Expansion Bus Expansion Bus Apps Processor Apps Processor Core Packet I/F Packet I/F TDM I/F DSP Core DSP Packet I/F TDM I/F Tandem Silicon Approaches • DSP/AP SoC solution • Moderate Power • Moderate Footprint • Complex PCB Design • Dual track tool chains • Increased/specialized training App App VoIP VoIP • Dual chip solution • High Power • Large Footprint • Complex PCB Design • Dual track tool chains • Increased/specialized training Dual Core Dual Chip Source: Trinity Convergence
