3. 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 NexTone MSX/RSM Equipment which interops with more than 700 networks worldwide with an ability to carrying more than 500 million VoIP minutes per month Peering Partners can provide solutions for wholesale peering, hosted telephony, NGN networks and IMS (3G IMS Mobile) including hosted Fraud Management Systems which we can provide to supplement your business analytics.

4. Why Peering Partners? …best practice VoIP Interconnect for wholesale telephony …optimized for a wholesale trading environment Why Peering Partners IPX? A hybrid VoIP 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)

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 VoIP Peering for BB Residential and Business providers seeking native IP interconnection Peering exchanges are now appearing all over Europe Regulatory Action is taking place

8. Gross margins can be greatly increased using VoIP suppliers Scaling VoIP peering is a very different from small scale point to point VoIP Networking Tech issues: protocol interworking, IP, NAT, security Operational visibility of VoIP performance Scaling VoIP 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 VoIP for wireline / wireless convergence (3G-IMS)

9. 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.

10. Endpoints (Gateways, User Agents IP-PBX, IP Phones) Firewalls Softswitch Call controllers Applications servers and Proxies

11. 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 VoIP peering, and hence no need for: IP-to-IP GW solutions for topology hiding and NAT VoIP NAT/Firewall solutions for network security Vendor-specific kit to facilitate vendor interworking (GKs, SIP Proxies, etc.) CDR collection and LCR solutions

12. Identify how you may evolve your core network and operations in ways that achieve the following: Deliver Deliver immediate functional capabilities that help achieve your wholesale service and sales objectives While building 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 VoIP-based interconnect parties Network model and facilities which do not require additional headcount and gateway/POP investment While sweating the assets of present network
