  • Reason we started w/VoIP due to phone number
  • 75% decrease in LD use in 5 years No change in local calling
  • Almost $1M on VoIP Usually a very fragmented university in terms of IT
  • All work well for basic service

    10. 10. Voice Infrastructure UM SL100 Local (soon?) and Long Distance Internet VoIP Cloud Legacy Line Legacy Set (35,000) Unified Messaging Campus Network VoIP Set (1,500) Analog Gateway Legacy Set Legacy Line Legacy VoIP Mobile
    11. 11. Complete Campus VoIP Options <ul><li>Pure VoIP (full speed ahead for a campus-wide deployment) - ”PUSH” approach </li></ul><ul><ul><li>Would require an investment of at least $8M over 5 years </li></ul></ul><ul><ul><li>Net effect=$370K in additional cost over 5 years </li></ul></ul><ul><ul><li>Does not include cost of separate network for VoIP, additional UPS’, network upgrades, or end user/admin cost shift </li></ul></ul><ul><li>Digital-Analog Gateway - “PUSH” approach </li></ul><ul><ul><li>An interim solution only. Would free up machine room space from main switch and switch itself, removing legacy maintenance expenses. Users could move equipment easily and feature changes are software. </li></ul></ul><ul><ul><li>Would require an investment of $6M over 5 years </li></ul></ul><ul><ul><li>Net= $920K in savings over 5 years (assumes “dedicated plant” model; most of savings is “dedicated plant”) </li></ul></ul>
    12. 12. Complete Campus Legacy TDM Option <ul><li>Move to “Dedicated Plant” and improvements in workflow </li></ul><ul><ul><li>Reducing the cost of MAC’s (especially Moves and Adds) </li></ul></ul><ul><ul><li>Re-engineering the order and billing process </li></ul></ul><ul><ul><li>Estimated reduction of 9 FTE for savings over 5 yrs=$3.5M </li></ul></ul><ul><li>… and implement “pull” VoIP </li></ul>
    13. 13. VoIP Plans for Next 1-2 Years <ul><li>Continue to replace Centrex with VoIP as needed </li></ul><ul><li>Consider VoIP for local service </li></ul><ul><li>Continue to use VoIP for temporary rental spaces </li></ul><ul><li>Continue to deploy VoIP when units choose it, but, with SIP-based systems (VoIP sets, Softphone, or Analog-Gateways) </li></ul><ul><ul><li>RFP for VoIP equipment will allow an upgrade to SIP-based systems instead of current proprietary systems. RFP for software solution (“softphone”) for any users who wish to use it (2,000 stations estimated) </li></ul></ul><ul><li>In new buildings, deploy VoIP or legacy depending on cost and department choice </li></ul><ul><li>Encourage departments to “harden” the campus infrastructure throughout campus as opportunity exists </li></ul><ul><li>Wait for the right ROI/functionality/reliability/security combination before complete legacy conversion </li></ul>
    14. 14. Complete VoIP Conversion - When? <ul><li>Not useful at U-M to simply replace legacy sets with desktop VoIP sets </li></ul><ul><li>Major shift is expected with: </li></ul><ul><ul><li>Leveraging personal cell phones for business use </li></ul></ul><ul><ul><ul><li>VoIP/wireless capable mobile phones </li></ul></ul></ul><ul><ul><ul><li>Sourcing to mobile carriers </li></ul></ul></ul><ul><ul><li>Legacy equipment is no longer supported by vendor </li></ul></ul>
    15. 15. Mobile - Future 1 Internet VoIP Cloud Campus Network Wireless Access Point Cellular & VoIP/WiFi Phone Wireless Access Point Broadband Residence Campus Cellular & VoIP/WiFi Phone The same mobile device will work in a residence to access personal service and on campus to access business service
    16. 16. Mobile - Future 2 <ul><li>Use current cell phone technology </li></ul><ul><li>Incoming call </li></ul><ul><ul><li>Use follow-me/find-me service </li></ul></ul><ul><ul><li>Redirect incoming calls to personal cell phone </li></ul></ul><ul><ul><li>Don’t impact personal calling plan, Carrier charges U-M </li></ul></ul><ul><li>Outgoing call </li></ul><ul><ul><li>Enter code so carrier knows it’s a business call </li></ul></ul><ul><ul><li>Deliver U-M caller ID info </li></ul></ul><ul><ul><li>Don’t impact personal calling plan, Carrier charges U-M </li></ul></ul><ul><li>Carrier cooperation </li></ul><ul><li>Unusual carrier negotiation </li></ul><ul><li>Coverage </li></ul>
