  1. University of California, IrvineIP Telephony Strategy and Deployment Brian Buckler, Assistant Director Network & Telecom Operations Network & Academic Computing Services

  2. Presentation Outline • Existing telephone & network infrastructure • General migration strategy • VoIP pilot project • First production implementation • VoIP challenges • Conclusions • Q & A

  3. Existing Voice Infrastructure • Ericsson MD110 PBX • www.ericsson.com/enterprise/products/md110.shtml • Installed in early ‘80s • On-going upgrades • BC11 (supports Ericsson IP phones) • Meets our needs: • Distributed • Flexible • Reliable • Scaleable • Roadmap to IP Telephony

  4. Existing Network Infrastructure • Cisco network with 20,000 hosts • Core: GE, No multicast, No QOS • Distribution: 100MB & GE • Edge: • Primarily 10MB switched • Some switched 100MB and GE • Cat3, Cat5, or 5E, future Cat6 • No power-over-Ethernet (POE) • Limited power backup systems

  5. General Migration Strategy • Leverage MD110 • Learn and gain experience • Train staff • Compare/evaluate vendor solutions • Watch industry trends and standards • Learn from experiences of others • Select a vendor solution • Migrate to VoIP - No “forklift upgrade”

  6. VoIP Pilot Projects • Evaluating Cisco and Ericsson solutions • Ericsson IP phones • Easy to integrate, but status quo • Weak market share • Cisco Pilot • Cool looking user-friendly phones • Interoperability issues • Strong marketshare

  7. 1st Production Implementation • Cal(IT)2 - Telecom Research Building • October 2004 • 100% Cisco IP phones • 50-100 phones • High-end Cisco network • Backup power system • An extension of our pilot project

  8. VoIP Challenges • Making a business case • Identifying value-adding applications • Selecting a vendor • Cost of properly designed network • Cost of hardening power

  9. More VoIP Challenges • Interoperability issues • Network security • All voice & data ‘Eggs’ in one basket • The ‘bleeding edge’ ?

  10. Conclusions • IP Telephony the way of the future • Cisco vs Ericsson vs others • Forklift vs migration • IP phones in new buildings • Network upgrade and power backup costs are high • Must have a good business plan

  11. Any Questions?
