Agenda Introduction to Peering Partner Network ◦ Wholesale Enhancement Network Example of a Business Case for Partners ◦ Fixed to Mobile Services - Furious Mobile Wholesale Technical Overview ◦ System Architecture ◦ System Details

Peering Partners - Network Overview Peering Partner's is owned and operated by IPX Voice Ltd a UK based company providing Managed IP Exchange Services Peering Partner's was founded in 2009 and focuses on the provision of hosted carrier to carrier services. The London Internet Exchange (LIX) is part of our IPX Cloud and we have point of presence installed in Harbour Exchange. We have IPX Clouds established in Europe and are planning further installations in South Africa, Hong Kong and Nigeria. Today, 5 out of the top 10 Global Wholesale Operators connected to our Network forming a Global LCR for our partners. Our NGN is based on Nex. Tone MSX/RSM Equipment which interops with more than 700 networks worldwide with an ability to carrying more than 500 million Vo. IP minutes per month Peering Partners can provide solutions for wholesale peering, hosted telephony, NGN networks and IMS (3 G IMS Mobile) including hosted Fraud Management Systems which we can provide to supplement your business analytics.

“Best of Breed” – Next Generation Networking (NGN) Why Peering Partners? ◦ …best practice Vo. IP Interconnect for wholesale telephony ◦ …optimized for a wholesale trading environment Why Peering Partners IPX? ◦ A hybrid Vo. IP system, incorporating multiple functions typically present in dispersed NGN/SBC and OSS/BSS components ◦ Greater Interoperability with all Carriers What does this “Best of Breed” technology incorporate / replace? ◦ Intelligent secure SBC (Session Border controller) ◦ Policy engine for Session Management ◦ Integrated OSS for systems, network and SLA management ◦ Class 4 routing engine ◦ Class 5 and VAS service brokerage (App Server OBP)

Peering Partners Interoperability Peering Partners use Nex. Tone systems which have been deployed to over 450+ carrier and service providers in 38 countries worldwide CONFIDENTIAL © 2010 Peering Partner's, All rights reserved.

Applications for our IPX Carrier to Carrier Peering ◦ Nex. Tone is the Market Leader ◦ Protocol IWF, Interoperability, Qo. S ◦ Topology Hiding, Call Admission Control ◦ MPLS VLANs, Nex. Tone Switch Partitioning Carrier to Enterprise Carrier to Consumer ◦ ◦ IP PBX interop – CCM, Avaya, Nortel Deployments w/Broad. Soft, Sylantro NAT Traversal, VLAN, Video Hoot-n-hollar (push-to-talk) ◦ Firewall/NAT, CALEA ◦ NAT Traversal, Outbound Proxy ◦ Call Center, IVR

Wholesale Business Trends Focus on larger ethnic routes for medium term growth ◦ India, China, SE Asia, large African countries, LATAM Serve smaller Ethnic markets for opportunistic trading opportunities ◦ Improve speed and reliability in working with local terminators directly ◦ Offer hosted/partitioned service to growing terminators Optimize Prepaid Calling card business ◦ Offer white-label version easily ◦ Introduce low-cost, high value VAS to enhance offering (Voicemail, Softphone, Presence) Become enablers of Vo. IP Peering for BB Residential and Business providers seeking native IP interconnection ◦ Peering exchanges are now appearing all over Europe ◦ Regulatory Action is taking place

Challenges / Opportunities for Peering Partners Gross margins can be greatly increased using Vo. IP suppliers Scaling Vo. IP peering is a very different from small scale point to point Vo. IP Networking ◦ Tech issues: protocol interworking, IP, NAT, security ◦ Operational visibility of Vo. IP performance Scaling Vo. IP while delivering quality that is at or better than TDM How to use 3 rd party networks to outsource non-strategic network functions (this is where the industry is going) How to future-proof Vo. IP for wireline / wireless convergence (3 G-IMS)

Peering Partners - Wholesale Peering Interconnect via Public and/or Private peering networks – Internet, Private peering, Private point to point connectivity Profile a customer/supplier in terms of Interconnect size, allowed routes, cost/profitability, performance and quality of service Apply business and engineering policies such as SLA, cost/revenue & minutes allowed to be exchange Variable route changes based on Most profitable route, historical performance and real time analysis of traffic patterns and network behaviour and network stabilisation to insure maximum traffic efficiency, reduced risk (Credit and revenue assurance) and flexibility to optimise customer and supplier routes and costs. Normalisation of rate sheets to reduce incorrect route/costs selection in LCR or routing plan Interworking of different protocols and equipment – SIP and H. 323 Signalling normalisation through Interoperating between difference manufactures equipment and software versions.

Tactical Business Drivers for Partners Immense flexibility in shifting large capacities of traffic: ◦ In real-time without waiting for TDM capacity ◦ Avoid network congestion and increase call completions ◦ Allows for more aggressive buying tactics than in TDM More complex LCR for deeper break-outs = higher GM% ◦ The IPX may break out up to 1 million dial patterns Capital efficiency and flexibility: ◦ Further “sweat” existing assets ◦ Flexibility to purchase other MG solutions easily (buying leverage and/or allowing the Carrier to chose the right MG for the right market/application) Complete solution for Vo. IP peering, and hence no need for: ◦ ◦ IP-to-IP GW solutions for topology hiding and NAT Vo. IP NAT/Firewall solutions for network security Vendor-specific kit to facilitate vendor interworking (GK’s, SIP Proxies, etc. ) CDR collection and LCR solutions

Partner Short Term Business Goals Identify how you may evolve your core network and operations in ways that achieve the following: Deliver immediate functional capabilities that help achieve your wholesale service and sales objectives While building an inherently valuable strategic architecture ◦ Flexibility to deliver new services with no network forklift ◦ ◦ Flexibility to easily provide service to a disparate universe of Vo. IP -based interconnect parties Network model and facilities which do not require additional headcount and gateway/POP investment While “sweating the assets” of present network
