2 Voice Over IP Are We Ready for Prime Time ? Melissa Martyr-Wagner Manager Of Customer Service - NTS Louis Hammond Assistant Director NTS

3 Goals of This Presentation Provide commentary on the voice & convergent communications market and suggest implications for higher education Discuss VoIP solutions, based on research findings as well as vendor proposals & presentations Highlight the pros & cons of an open source PBX solution Discuss a model for rollout of services

4 What have we been doing? 1998 Evaluated VOIP - It wasnt ready 2001 Completed a 35,000 port PBX upgrade 2004 Deployed a new E911 system 2004 Started evaluating a few VOIP platforms 2004 Started Beta testing with current vendor 2005 Completed a 60,000 port network upgrade for over 228 buildings

5 What have we been doing? 2005 Upgrading Voice Mail to Unified Messaging - 18,000 users 2005 Installed VOIP fed legacy PBX partition users 2004 Need to deploy VOIP services!

6 VOIP Gaining momentum After 10 years of relatively slow growth, VoIP is generating a renewed interest among consumers. –increase in broadband –improvements in quality of service –hookups that allow VoIP calls over ordinary telephone handsets

7 The Problem VOIP vendors and providers gaining momentum Vendor enterprise systems are marketing very nice systems Many Universities have on site PBXs Many have Local Centrex Services We dont want to get left behind

8 The Problem The Commercial Market is still flux –Vonage now for sale, AOL and Earthlink selling to residential, Packet8, Nikotel, NetCentrex, Broadsoft, etc –Microsoft ? –EBay to Acquire Skype –There are over 450 providers for US –

9 Decisions Many Universities have newer networks Closet infrastructure issues Many have Current PBXs that can integrate to VOIP Some have already implemented VOIP Lots of claims of cost savings Hidden costs

10 Our issues Current PBX depreciates in 2008 So far any VOIP platform is separate from current PBX and expensive Vendor support for SIP is limited Power issues for end stations Closets not ready-Few Generators and no UPSs

11 More issues to think about Network QOS - application or port based E911, CALEA, and Security Fire, life, and safety support issues Allowing phones to move about On and off campus

12 More issues to think about Soft Phones - XTEN, SJPhone, others Licensing Who owns the phone numbers Do you need phone numbers Call Centers and applications Proprietary or SIP based systems

13 More issues to think about VOIP over Wi-Fi Cell and Roaming Integrations Peer to Peer solutions Open Source ?

14 OpenSource SIPFoundry PingTel YATE Asterisk

15 Supports SIP Supports many vendor instruments Supports several softphones Supports video and presence Developed IAX and IAX2 protocols Has Unified Messaging/ can integrate

16 Asterisk Jabber and push to talk features Runs on many OSs Windows, MAC, Unix, Linux Can be built in high availability clusters Can peer with other Asterisk servers and PBXs








24 Asterisk Pros Truly free all you need is hardware Seems to be reliable - they do offer an enterprise version Application development Partnerships with many vendors Large co-operative support It works- turn key systems available

25 Asterisk Cons You cant blame the vendor You need to commit staff for this You need commit other resources to this Some integration interfaces need to be built

26 Our Plans Finish a few priority projects - UM, WIFI upgrade Finish a design effort, service plans, and bundles - We know it works lets get on with it Figure out 911 Use IAX2 devices as well as SIP Build up support

27 Our Plans Advertise supported solutions VOIP will be use to augment our current PBX Cost savings in new facilities and off site locations Figure out how to roam off campus We will be open to specialized Call Center solutions

28 Our Plans Continue to grow the VOIP offerings as a replacement strategy for the current PBX Make sure it is bullet proof Make sure its the right solution for the customer Be open to multiple solutions Begin peering with other institutions

29 Last Thoughts You should expect to be flexible and ready to try evolving elements as they become available it may be that the PBX as we know it will no longer be needed as more peer to peer and Opensource applications emerge
