15 Migrating Voice to IP Interconnections Problems & Opportunities Presented by Ian Campbell Director Product Development & Product Management

16 Agenda Introduction Why VoIP Interconnects? i3 Forum & GSM IPX Architectures Opportunities/Challenges Future interconnection architecture

17 Introduction Current Landscape TDM carries majority of international voice traffic: Milk investments in TDM switches Retail traffic is quality sensitive Service features deployed require use of SS7 to work correctly e.g. voic OCN/RDN; release/cause code mapping is not consistent But: VoIP used extensively in domestic and international wholesale: Access to emerging markets using public Internet as transport Interconnection to resellers and wholesalers ITSPs using VoIP to avoid conversion costs for interconnection

18 Cost Savings Transport cost reduction Carrier Ethernet/MPLS Better capital utilization Stop dual running of VoIP & TDM Opex cost reduction Business/Product New services on converged infrastructure Enhanced service features e.g. HD voice Competitive pressures Engineering/Operations Introduction VoIP Drivers Equipment obsolete replacement difficult Stop dual running VoIP & TDM reduce interworking complexities

19 i3 Forum & GSM IPX Architecture i3 Forum 35 Carriers committed to solving the remaining issues in VoIP interconnection ( Has provided recommendations and documentation for: Improving quality: Improved metrics MOS, NER, IP metrics IP QoS SLA end to end through multiple carriers Avoiding or eliminating transcoding

org) General structure for IP interconnection for not just mobile operators but all SPs.

20 i3 Forum & GSM IPX Architecture Feature interworking: Release code mapping SIP I SIGTRAN Fax over IP Security IPX Architecture ( General structure for IP interconnection for not just mobile operators but all SPs. i3 and GSMA collaborating on voice over IPX (VoIPX), unified approach toensure qualityandfeatureinterworking and interworking Further interworking provided for Data Roaming, SMS/MMS and new services

21 Opportunities/Challenges Opportunities: HD Voice quality well in excess of TDM using broadband codecs HD H Video Conferencing New services presence Cost savings and quality improvements on current voice Challenges: Routing & Addressing to support Peering Direct routing requires incremental knowledge: Number Portability in distant operator/country Service capabilities of end users HD voice capable? Integration of Peering and LCR approaches Economics of many direct peers versus using trusted partner Security and Fraud Prevention Transport Network Issues & IPv6

22 Need to balance: Direct peering routes Peering via Intermediaries Termination offered by partners Termination via PSTN carriers Select routing based on Price, Quality and Policy choices

29 Standards in the Space IPX and I3F: GSM Association (GSMA) Guidelines defined by GSMA to primarily connect mobile carriers and other mobiles Mainly represented by European mobile network operators initially. Now includes fixed operators together with operators from Asia and USA. I3F created independently, with emphasis on wholesale carriers IPIA and I3F joint forces to drive IPX specifications and establish VoIPX WG. Does not cover TDM IP interconnect SPEERMINT IETF New working group created for defining Session PEERing for Multimedia INTerconnect (SPEERMINT) reference architecture at technical level only and for layer 5 SIP peering only. Defines SBC behaviour for enterprise-enterprise peering & Carrier-Enterprise & Carrier-Carrier peering. Driven mainly by US operators (Verizon, Global Crossing, etc, Cable Labs and BC vendors (ACME, Juniper) Enterprise-enterprise, SIP Service Provider (SSP)-SSP, Enterprise SSP, across public or private internet. IMS; ITU-T NGN: ETSI TISPAN None go into details to enable open interoperability. IMS vaguely defined interconnect between IMS networks from the CSCF via a BCF & TrGW. ITU-NGN simply indicated the use of BCF but also state that PSTN Emulation Subsystem should use SIP-I TISPAN NGN indicate use I-BCF and BGF. 29

30 Global Operator Interconnect SWOT Analysis STRENGTHS Capitalize on current business and brand equity Incumbent s % ownership of Interconnect Traffic Global reach & business relationships OPPORTUNITIES Exploit network footprint (nationally & internationally) Capture new markets through initiatives such as GSMA IPX Create powerful interconnect capabilities with other providers and partners Reduction in OpEx (through technology consolidation) + _ WEAKNESSES Complexity of network transformation programs Perceived cannibalization of existing TDM interconnect revenue streams Slower velocity on adoption of VoIP at the interconnect THREATS Over the Top Voice Suppliers and nimble smaller operators Other Global Operators grabbing market share early Gradual erosion of TDM Voice Interconnection revenues Operators know they must act to secure future revenue streams 30

31 The Operator Challenge How to act? How does the business economic model need to change? What new market opportunities can be exploited? What technology choices should be made? Mitigate impact of TDM interconnect cannibalization Loss of traffic (mobile substitution, Over the top Voice providers, other new market entrants etc) Does price erosion and highly competitive market economically sustain existing TDM interconnect model? Does VoIP provide the means to reduce comparative OpEx & CapEx costs (incl. retirement of legacy Gateway switches)? When is the right time to react (inflection point)? What is the strategy for staking a major role in the evolving VoIP interconnect market? How can the needs of interconnectivity between Fixed and Mobile Operators be met today (without the requirement for significant capital investment)? How can existing investments (such as wide area IP/IMPLS networks) be exploited? Should I wait for interconnect standards efforts to gain momentum (example GSMA IPX/IPI)? Where can VoIP be exploited? (how to align with strategy of interconnection partners)? How do align the solution to my own network transformation programs (do I collect traffic via TDM or VoIP from my own network)? How can a I build a common solution to handle multiple scenarios (IP TDM, TDM IP, IP IP etc)? How can I align with standards and ensure investment protection against technology choices made? 31
