1. Voice over IP (VoIP) and Unified Messaging (UM) -- NETS testing update NCAB Presentation 19-Dec-2001 Jeff Custard Teresa Shibao Jim VanDyke

2. Outline for today’s presentation Current System Phone Voice Mail VoIP Review Compare current system to VoIP Messaging Review voice messaging and unified messaging Compare current VM to new VM/UM options Futures Deployment Remaining tests, etc.

3. Review of current phone and voice mail system

4. Current system review 5 systems with over 2500 active ports (phones, trunks)

5. Current telephone system Siemens 9751 v6.4 –Components and software are proprietary Redundant telephony processors at ML and FL only Using “Classic” ROLM phones from previous systems, some purchased w/original system in 1984

6. Current system life Current PBXs scheduled replacement for FY‘04, ‘05, ‘06, and ‘07 –Next generation traditional? –VoIP solution? Telephony vendor’s platforms are hybrid VoIP /traditional systems Port cost comparisons

7. Current voice messaging ROLM PhoneMail v6.3 –PC-based systems –386/33mhz processors 1200 subscribers Backups only save database tables, no messages/greetings ML and FL purchased 1991, due for replacement this year

8. Voice over IP (VoIP)

9. VoIP review

10. Phone basics

11. Data port on phone Data port included on phone, keeps port count down Cost model implications (changed physical infrastructure requirements) Two VLANs—1 for data; 1 for voice 10/100 port; auto-negotiate or hard- set

12. VoIP – a typical migration

13. Our deployed VoIP NETS test bed –Cisco Call Manager –Cisco Unity –IP Phones –PBX connectivity Marshall Field Site (MFS) production network

14. Marshall Field Site (MFS) 4 analog lines on FXS ports on a Cisco 3640 2 Cisco 7960 IP phones –1 in data closet –1 over MFS WLAN Current diagram:

16. Lessons learned so far FXS ports only “drive” (i.e., ring) one analog phone (with mechanical ringer) Echo cancellation settings require some tweaking We’ve learned a lot about dial-peers and call-legs (VoIP call troubleshooting) For better perceived voice quality, turned “Voice Activity Detection” (VAD) off QoS testing –Early Field Test code is risky business!

17. IP phones tested 7910 (2x24 LCD display) “lobby phone” – can get with or without switch 7935 (conference phone) – initial test results unsatisfactory –Will try again on ISDN PRI PBX connection to see if perceived voice quality improves Cisco “Soft Phone” 7960 (6 line phone with larger LCD screen) –will soon be testing a 7914—14 line expansion module

18. Call Manager Compaq Proliant DL380 server Windows 2000 Server Internet Information Server 5 Cisco Call Manager software

19. VoIP vs. traditional PBX What’s the difference?

20. System administration

22. System redundancy

23. CM administration Done via web interface

24. 7960 user interface Basic interaction with phone menus User configuration option on CM web page –Speed dial button updates –Password changes –Service subscription –Personal directory (links to this in next release of CM)

25. Phone feature comparisons

29. Voice Mail (VM) and Unified Messaging (UM)

30. VM replacement issues Voice messaging scheduled for this year –Voice messaging only? –Unified messaging solution? Most products currently on the market are Microsoft server based Currently evaluating options –Cisco Unity is one potential candidate Cost comparisons

31. Unified Messaging (UM) – what is it? “Converged” email, voice, and fax messaging –email, voice and fax messages accessed from PC or telephone Text-to-speech module can read email over the phone Fax server allows centralized fax management –view, print, or forward via email client Browser-based personal administration –allows users to make their own customizations

32. UM benefits: Centralized communications control Browser-based administration Decentralized routine administration Scalable, redundant, fault-tolerant system tools

33. Cisco Unity overview Cisco Unity (formerly Active Voice) –Compaq Proliant DL380 server –Windows 2000 Server –Exchange 2000 mail store –SQL 2000 data store –Internet Information Server 5

34. Cisco Unity Heavily reliant on Microsoft products (Windows 2000 server, Exchange 2000, SQL 2000 server, Outlook client, Internet Explorer for maintenance, etc.) Would need to purchase anti-virus software for email server(s) Would need to purchase backup software for server(s)

35. Unity user interface overview Basic voice-mail functionality (via the phone) “Active Assistant” web interface to change phone mail options Email send/receive for voice mail messages Outlook available via Exchange web interface (not the same feature set as standard Outlook client) Fax send/receive LDAP server connectivity

36. Unity admin overview Web interface for most tasks

37. Next steps Install/test ISDN PRI T-1 –Digital lines between gateway and PBX will replace current E&M analog lines Continued CM and UM testing –interaction with existing email servers Continued QoS investigation/testing Continued fax server testing

38. Deployment issues Time-frame?
