3 VoIP Seminar, April 3 Concept of seminar: o o o VoIP Workshop VoIP is an accepted technology Educational institutions see VoIP as an alternative to traditional telephony Understanding status of VoIP is essential One-day seminar on the state of the art in VoIP implementations in education Presentations, case studies, technical and policy issues, disruptive technologies, discussions

4 Speakers Walt Magnussen, Texas A&M VoIP Workshop Kenneth Green, Campus Computing Project Dennis Baron, MIT Brenda Helminen, MTU Dewitt Latimer, Notre Dame Pradip Patel, UM Jim Moran, Merit Mark Iannuzzi, TelNet Worldwide

5 VoIP is inevitable Walt Magnussen, TAMU VoIP Workshop Traditional TDM phone systems at end of life Most enterprises transitioning to IP-based telephony ACUTA Survey (2007) 76% or campuses had a positive outlook on VoIP Only 4% of the responding campuses have >75% of their campus converted Only 4% of the campuses have >75% of their LD minutes sent as IP calls 8% of the respondents felt that VoIP would less expensive

6 Walt Magnussen, TAMU With VoIP all applications VoIP become: Workshop Easier to develop, easier to integrate with other services, less expensive Discussion of development of NG911, with IP from end to end SIP, and Wireless to SIP Disaster communication IPTV VoIP is inevitable, but We have a long way to go Its not about saving dollars

7 Kenneth Green, C. C. Project Campus Computing Project Multi-year study of tech issues in higher education All types of organizations, issues Includes questions about telephony, VoIP

10 Dennis Baron, MIT SIP experimentation started in 2003 VoIP Workshop VoIP pilot in 2007 Phased deployment began in January ,000-15,000 phones to be transitioned Rollout to take ~ 2.5 years Deployment criteria: New construction (no telco wiring) VoIP Pilot groups (partially transitioned) Building renovation or group move Buildings with adequate infrastructure (wiring, data closets) Department readiness

11 Brenda Helminen, MTU VoIP Workshop Began work in spring 2000 Contract for Centrex service ending 2003 Converged network/telephone staff Robust data network & physical infrastructure MTU already doing video over IP; IP technology fit our strategic goals. MTU in a good position to leap frog classic PBX technology if IP telephony was mature enough to implement.

12 Brenda Helminen, MTU The primary goals of VoIP this project Workshop are to stabilize the cost of telephone service for campus and to enhance the business support functionality of our telephone service. Key decisions: User Power over Ethernet switches Deploy UPS broadly Service Quality Engineering Separate VLANs for voice; low oversubscription Management Tools Automated configuration; Web interfaces

13 Brenda Helminen, MTU Key benefits: VoIP Workshop All work orders are minor variations of the same basic process. One technician can do all network and telephone work orders. Troubleshooting has become more standardized. Services to remote sites cost effective with no reduced functionality. Easy ability to add new POE services (WAPs, IP security cameras, card readers)

14 Dewitt Latimer, Notre Dame Hosted VoIP Services VoIP at the University Workshop of Notre Dame: 4 Years of Trials and Tribulations If most campus telecomm/video/data operations were not a monopoly on campus How long do you think they would last in a free-market economy where the consumers have freedom of choice? Guiding principle: Notre Dame is convinced that advanced communication services with a heavy emphasis on mobility and integrated wireless will be required to run the modern university with an increasingly mobile constituent group and doing so was not within the core mission of the University

15 Dewitt Latimer, Notre Dame Historically a Centrex VoIP operation; Workshop approached 2005 end of contract Goals: Close to zero capital expense and ownership, minimal exit costs Short-term contract, no minimums Tight integration with wireless provider for mobility Transition not a flash cutover Chose hosted solution via SBC that would fit these and provide other benefits (with acknowledged downsides)

16 Dewitt Latimer, Notre Dame Initial trial rollout took VoIP 12 months Workshop to develop equivalent services All going fine until AT&T acquisition Key change in technology took transition back to day 1 Making progress until BellSouth merger came up lost 12 months of development Tried to make it work but delays, shortcomings: ND pulled plug on 3/1/08 Still looking for managed service

17 Pradip Patel, UM Described several experiments VoIP Workshop UM has conducted with vendors to try out ideas in VoIP and wireless convergence Goals: Find, resolve cellular coverage issues Integration with campus services Reduce cost Allow single device Leverage user assets (students, faculty & staff) Technology understanding Integration options with carriers

18 Pradip Patel, UM Experiment with hospital VoIP to give Workshop physicians BlueTooth headsets for easy communication Trial with VeriSign on dual-mode functions Cisco inbound call mobility (incoming call goes to two devices) T-Mobile, Nokia, SIP and Cisco dual-mode handset Examination of how campus network connects with carrier networks Several others

19 MeritVoice Reasons for service: Membership moving to VoIP VoIP Workshop Leverage the backbone; backbone & many Member attachments with extra capacity Economies of scale Just another network service VoIP Offerings PRI Replacement via IP-based SIP trunks Managed Service/Hosted PBX

20 MeritVoice Merit/TelNet interconnection VoIP Workshop TelNet has switches in all five Michigan LATAs Merit will peer with TelNets network in four locations Connections to individual Merit Members via fiber (ideally) PRI Replacement via IP-based SIP trunks Link PBX to Internet connection and reduce amount of traditional telephone connectivity via PRI

21 MeritVoice Managed Service/Hosted VoIP PBXWorkshop Hosted virtual PBX or Centrex service offers a comprehensive business feature set using IP or legacy phones Virtual Private Network Virtual Phone Numbers Voice, Video Conferencing, Whiteboard Unified Messaging, Presence Fixed-Mobile Queue/ACD 911 Multicast Multimedia Broadcasting

22 Themes Summary of the day Many parts of VoIP are stable Technology is still evolving VoIP Workshop Advanced services are still being invented and developed Integration with cellular infrastructures is important and unresolved
