It IS the Internet – just extended: + Delivery to the users, on LANs and to smart phones + Prioritization for real-time traffic - Just enable diffserv + Metering and charging of “beyond Internet usage” Good for everyone: also for the Telcos: The SDN is not needed, Provide something better, - IP connects end-to-end - and users will pay for it. . - SIP is a self-routing Bill the better! © 2012 Intertex Data AB 4

Sorry, it’s POTSo. IP Ø SIP has been Used to Replace Pieces of the PSTN Maintaining Old Structures POTSo. IP § We had a cloud that could transport all communication, including voice and UC. § Today, we use the Internet for all smart communication, but lack global real-time communication, multimedia or UC. § We get the 100 years Plain Old Telephony Service (POTS) maybe cheaper and more flexible. But is the way forward? Session Delivery Network (SDN) and IMS © 2012 Intertex Data AB 6

Internet has Shown the Success of a Cloud! We need this for global UC: SIP Connect 1. 1 Internet+ With: 1. All you can do with SIP - UC 2. Full mobility 3. Numbers and SIP addresses 4. Quality up to Telepresence 5. Interoperability – Don’t GW, unless required 6. Delivery to the users But got this (SDN/IMS): (Wires on top of the cloud!? Wasn’t creating the cloud the success? ) Internet MPLS Session Delivery Network (SDN) = POTSo. IP

We Are (sometimes) Doing Better! SIP Trunking SIP System Provider GW PSTN UC Voice Mail Remote Users SIParator® IP-PBX Ingate/Intertex E-SBCs enable SIP based Live UC Across the Borders! (SIP does not traverse ordinary NAT/Firewalls. ) Data & Vo. IP LAN Users and Services can be Everywhere: SIP must connect there! © 2012 Intertex Data AB 8

It Should be of Utmost Interest for the Telcos Internet and Telephony Economy Internet + Economy Bandwidth Usage Data Low Charged Internet Bandwidth Data RTC Skype etc. RTC Telephony+ Telephony Income (highly charged) Quality Bandwidth New Income Ø For real-time usage, we need an Internet pipe with prioritization enabled not just for telepresence quality, but also for 2 G, 3 G and 4 G wireless real-time usage with smart phones § Has to be charged separately. If not, it would be used for everything and we are back at all usage being at the same quality level. Ø And we don’t want our smart phone batteries drained Ø And we want to use both phone number and addresses – not the many island. © 2012 Intertex Data AB 10

Internet+ Model The Internet with Quality Enabled Global IP Transport Network SIP Connect 1. 1 PKI DNS EMS ENUM TR 069 All SIP Routed Everywhere (Not Gatewayed! Via SIP Proxies – Not B 2 BUAs) The TOQrouter – Trust, Openness, Quality – is a routing SIP proxy, a billing meter, and with built in SBC.

Most Important: SIP Everywhere – Just like HTTP! We would not have the Web, if HTTP did not go between the Browser and the Web server. Today SIP is stopped and limited by Firewall/NATs, Soft. Switches and bad SBCs. The TOQrouter is a standard compliant SIP proxy (and SBC) that routes all SIP between the Users and Servers according to RCF 3261. The TOQrouter is not interfering with the usage of the SIP communication (like today’s plumbing), but can measure the usage for billing. Proper SIP transport (by routing SIP proxies) is required: • For all beyond POTS usage, UC • For eliminating network incompatibilities – Interop issues are then reduced to being only between clients and services • For mobility: User and services can be anywhere! • For global UC: Clients, PBXs, Cloud services etc. only have to use a standard SIP interface. There is no other way to go!
