2. 2 The Future of Communications  Context-aware  Session, not call-based  User-oriented  Multi-modal Today  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… PSTN  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

3. 3 The Future of Voice  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 Context Preferences Network Capabilities Device Capabilities Voice Video Text Data TDM IP Signaling Codec Enterprise Data Social Networks Web Search… AnonymityTime of Day Caller IDContext… Voice 2.0

4. 4  Where are we today  What’s possible  How do we get there Agenda What % of students subscribe to your campus telecom service?

5. 5 Telecom’s Historical Role University Telecom Service Students FacultyStaff

6. 6 Today University Telecom Service Wireless Wireline Email SMS VoIPIM Students Faculty Staff Students Faculty Staff  Multiple, disparate networks  Varied communication formats

7. 7 Today’s Environment  Broadband throughout campus  Ethernet  WiFi Network  Voice Services  Video  Data  5 digit calling  Caller ID  Voicemail Services  Call waiting  Call forwarding  … Your competition:

8. 8 Your Challenge  Provide reliable and high-value communications services to campus “customers”  Connect increasingly isolated communities  Knowledge exchange  Collaboration  Emergency services  Meet (and exceed) expectations of increasingly sophisticated users

9. 9  Where are we today  What’s possible  How do we get there Agenda Who offers: voice? data? video? Who offers services beyond “triple play” bundle?

10. 10 Mobility  SMS  Media exchange  Community collaboration/notification  Public safety  WiFi  VoWiFi  Campus PBX extension  Cellular  Dual mode – VoWiFi, FMC  University client  MVNO

12. 12 Collaboration & Knowledge Exchange  Conferencing  SMS/Mobile  VoIP/virtual meeting room  Video  Collaboration  Widgets– context & relevance  Data integration  Consolidated identity/ unified messaging & calling

13. 13  Where are we today  What’s possible  How do we get there Agenda Who operates telecom services in-house? (On-site PBX, etc.) Who outsources one or more components of their telecom service?

14. 14 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 Path to the Future

15. 15 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 Path to the Future

16. 16 Sample ENUM Query E.164 TN +16505259200 0.0.2.9.5.2.5.0.5.6.1.e164.arpa NAPTR Record NAPTR 10 100 "u" "E2U+sip" "!^.*$!sip:info@example.com!" InputOutput mailto: h323: Telephone number in, IP out

17. 17 Consolidating User Identity Wireless Wireline Email VoIP IM ENUM provides…  A universal addressing scheme for IP  Foundation for enhanced services ENUM

18. 18 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 Path to the Future

19. 19 Network Evolution  Vertically integrated  Monolithic  Discrete, specialized networks  Network defines the service Legacy Networks Transport Signaling/ Session Control Applications VoiceDataApp n Next-Gen Networks  Disaggregation & horizontal specialization  Abstracted network infrastructure  Commoditization of transport  Application developer defines the service Transition has already started Value
