  1. Benefits of VoIP Peering in a Challenging Economy(SP-10)Tuesday - 02/03/09 4:00-4:45pm Mark Benisz, VP Americas, XConnect Global Networks

  2. Agenda • VoIP Peering in a challenging Economy • Best practices for NGN interconnects: bilateral, multilateral and federated • Registry vs. Signaling approaches to peering • Number portability and ENUM • Regional and Global Peering trends • How peering enables new high margin services: video, high quality audio • Commercial benefits and case studies

  3. IP Communications & NGN Adoption Voice over Broadband Adoption – Residential Lines

  4. Cable VoIP Services Global Enterprises VoIP /NGN Service Providers PSTN 3G Mobile / IMS Web based VoIP services Intermediate Result: VoIP/NGN Islands

  5. Today’s Telephony Challenge How to get all the disparate pieces of the global network puzzle working together?

  6. Peering brings all the parts together Enable groups of service providers to multi-laterally exchange calls with each other via IP, based on a set of administrative terms for settlement, policy and interconnection

  7. Best Practices for NGN Interconnects • Bilateral • Resource intensive • Not scalable • Multilateral • One interconnect • Possibility of one commercial contract • Minimal use of internal resources • Network upgrades • Federated • Members control policy • Trust • Commercials

  8. Registry identifies service provider or entity identify actual egress point Optimize routing Enables most efficient routing mechanism voice video push-to-talk SMS new IP features Signaling Enables scalable interconnection Signaling Hub Enables signaling management multi-protocol, Registry vs. Signaling Functions

  9. Physical Transport Discovery / Location(ENUM Registry) Signalling Interoperability Standard IP Peering / Connectivity - Public, Private, Ethernet Which calls terminate to another VSP, and where should they be routed? How can signalling interoperability be ensured with different protocols, variants & implementations? Policy, Trust & Security Media Handling Commercial Who should calls be received from & on what basis? How to protect subscribers from abuse (SPIT, vishing)? NAT traversal and codec incompatibility Based on policy and traffic profiles, should calls be settlement-based or settlement-free (Bill & Keep)? Challenges

  10. LNP and ENUM • Number portability (local, mobile or full) is now available in US, Canada, Mexico and Brazil • All Call Query (ACQ) • Central Registry Approach • Call Forwarding Approach • Typically delivered via SS7/ C7 • ENUM Registries • Private routing, public registry, carrier ENUM via ACQ • Can be LNP corrected • Enables expansion of ACQ to other Registry information beyond NP • Features supported (video, wideband codecs, Presence) • Call forwarding, call forking, non-traditional number plans

  11. Regional and Global Peering trends • Regional • Netherlands - JCC MSO peering • Brazil - VoIP peering federation • UK - BT IP Exchange • USA - Cablelabs • Global • GSMA • i3 Forum • Peering Service Providers

  12. New High Margin Services High fidelity audio Video telephony IM integration Vanity Numbers/ DIDs Not just low cost voice

  13. Peering to IM Service Providers • Differentiate service from PSTN • Peer VoIP Networks with voice-enabled IM communities. • Call IM communities – by dialing a numeric phone • IM user can call back whenever they want. • Discover/Provision IM buddy numbers • using a web page. • Number assigned to the IM client can be: • private number • conventional e.164 number
