1. Voice and Integrated Communications (VICI) TDD All-Hands Meeting December 14, 2005 Ben Teitelbaum

2. 2 Need for New Campus Communications Services  Voice was once revenue-generating for many schools; no longer  Users have adopted consumer services to meet personal / profession needs Cellular Consumer IM&P (e.g. AIM, YIM, MSN) Consumer VoIP (e.g. Skype, FWD)  How can universities develop services to: Recapture these customers? Enhance the campus life experience? Facilitate collaborative research? Improve productivity?

3. 3 Connectivity for Real-Time Communications Bob Alice User Campus / Enterprise UserAbilene + Regionals Campus / Enterprise Host Network-Layer Connectivity high-performance, end-to-end IP transit High-performance, end-to-end IP connectivity is necessary, but not sufficient to connect Alice with Bob ?!!?

4. 4 Bob Alice Bob Today: 3 rd Party ASPs Provide the Missing Middleware User Campus / Enterprise UserAbilene + Regionals Campus / Enterprise Host Network-Layer Connectivity Applications 3 rd Party ASPs Skype high-performance, end-to-end IP transit FWDYahoo!… ? Communications is Balkanized by competing 3 rd parties, who are unable to provide strong authentication, identity management, or rich presence for their users ?

11. 11 PSTN Big Problem How to SIP from a 12-key phone? IP Desk Phones Cell Phones Legacy Desk Phones

12. 12 Internet Subscriber Numbers  4257*260  Like ENUM, but nearly flat hierarchy  TRIP [RFC3219] ITADs Globally unique IANA is already set up to allocate them locally assigned ITAD (Internet Telephony Administrative Domain)

13. 13  Take an E.164 number  Convert it to FQDN  Query DNS for NAPTRs  Apply resulting regexs to get list of URIs: ENUM in a Nutshell +1-734-913-4257 7.5.2.4.3.1.9.4.3.7.1.e164.arpa. sip:bdr@internet2.edu mailto:bdr@internet2.edu sip:bobr_621@att.sbc.com e164.arpa. 1.e164.arpa. 4.3.7.1e164.arpa.x.x.x.1.e164.arpa.

14. 14  Take an ISN  Convert it to FQDN  Query DNS for NAPTRs  Apply resulting regexs to get list of URIs: ISN in a Nutshell 4257*260 4257.260.freenum.org. sip:bdr@internet2.edu mailto:bdr@internet2.edu xmpp:bdr@internet2.edu freenum.org. 260.freenum.org.
