The Future of Communications We just received a bg order. I know, I’ll get started on it right away. I saw your IM for next week’s meeting. My calendar has blocked out a time to discuss that later. Future IP Today PSTN Hi, are you busy? No. I called your mobile, is this the best way to reach you? Ring my office next time. I wanted to talk about our meeting next week. Can we chat later? That will be a long conversation. Bye. Wait, we just received a big order… Context-aware Session, not call-based User-oriented Multi-modal

The Future of Voice Context Device Capabilities Network Capabilities Enterprise Data Social Networks Web Search … Context Voice 2.0 Voice TDM Device Capabilities Network Capabilities Video Signaling Text IP Codec Data Preferences Anonymity Time of Day Caller ID Context … Standards-based, any-to-any connectivity Seamless communications anywhere, any time, over any device Communications sessions defined by user preferences, not arbitrary network boundaries Context and relevance embedded in communications

Agenda Where are we today What’s possible How do we get there What % of students subscribe to your campus telecom service?

Your competition: Today’s Environment Services Services Network 5 digit calling Caller ID Voicemail Call waiting Call forwarding … Services Voice Video Data Network Broadband throughout campus Ethernet WiFi Your competition:

Meet (and exceed) expectations of increasingly sophisticated users Your Challenge Provide reliable and high-value communications services to campus “customers” Meet (and exceed) expectations of increasingly sophisticated users Connect increasingly isolated communities Knowledge exchange Collaboration Emergency services

Agenda Where are we today What’s possible How do we get there Who offers: voice? data? video? Who offers services beyond “triple play” bundle?

Agenda Where are we today What’s possible How do we get there Who operates telecom services in-house? (On-site PBX, etc.) Who outsources one or more components of their telecom service?

Path to the Future 1. Determine your focus Consider your mission and core competencies Do you want to be a network operator, an IT shop, or an application developer? Offload non-critical operations for greater efficiency

2. Connect user “islands” Path to the Future 2. Connect user “islands” IP is the common denominator, but… Interoperability is not guaranteed Media encoding Session creation/management Consolidated user identity is critical Comprehensive mapping of communication devices and networks (data store of record) User preferences and availability ENUM is the solution

Consolidating User Identity ENUM provides… A universal addressing scheme for IP Foundation for enhanced services VoIP Wireless Wireline ENUM Email IM

3. Build communications development environment Path to the Future 3. Build communications development environment No “killer” application, only the “killer” environment Flexibility and rapid innovation are critical Search out partners and vendors that accelerate your innovation Complete solution offer (application/connectivity/transport) Hosted environment to reduce risk Community leverage Commercial experience and feature set

Transition has already started Signaling/ Session Control Network Evolution Legacy Networks Next-Gen Networks Applications Voice Data App n Value Transition has already started Signaling/ Session Control Transport Advantages in consolidated stack: -single-source offer to non-voice customers -CDR collection helps apps Vertically integrated Monolithic Discrete, specialized networks Network defines the service Disaggregation & horizontal specialization Abstracted network infrastructure Commoditization of transport Application developer defines the service

VoIP Applications Environment Consolidated environment for the creation of enhanced communications applications Applications – “Plug and play” applications easily extend basic VoIP feature set Core Application Services – Reusable service building blocks provide abstracted access to core services required for application setup and call completion Registry & Transport– Eliminates PSTN transport and maps legacy to IP end point domains (DIDs, cross connect, media conversion, etc.) Community Application Screen Pop/ Web Integration Positional Voice/ Conferencing Enhanced 411/ Virtual Assistant Community Application Click to Call Applications Mobile Client Desktop Client Call Control API SMS/MMS API Web/Data API Location/ Presence API Core Application Services ENUM/LNP Registry Signaling Interworking TDM/IP Transport CODEC Translation Transport
