1. Voice over IP (VoIP) and Unified Messaging (UM) - NETS testing update NETS Presentation - 11-Dec-2001 Jeff Custard Teresa Shibao Jim VanDyke

2. Overview of work to date Initial setup and testing “sandbox” MFS deployment drove: –Deployment on VLAN245 (on 6509s, 3524s, and 5500s) CM upgrades Various equipment tests Unified Messaging (Cisco Unity) server setup/testing

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

5. MFS – lessons learned FXS ports only “drive” (i.e., ring) one analog phone (with mechanical ringer) Tweaked echo cancellation settings Learned a lot about dial-peers and call- legs (VoIP call troubleshooting) For better perceived voice quality, turn “Voice Activity Detection” (VAD) off Serial connections are still annoying and pesky but we made them work QoS testing –Early Field Test code is risky business!

6. 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 connection to see if perceived voice quality improves SoftPhone 7960 (6 line phone with larger LCD screen) –will soon be testing a 7914—14 line expansion module

7. 7960 user interface Basic interaction with phone menus User configuration option on CM web page –Speed dial button updates –Password changes –Personal directory (links to this in next release of CM)

8. Call Manager Admin Interface Compaq Proliant DL380 server Windows 2000 Server Internet Information Server 5 Cisco Call Manager

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

13. System Administration

15. System Redundancy

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

17. 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

18. UM benefits: centralized communications control browser-based administration decentralized routine administration scalable, redundant, fault-tolerant system tools

19. 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

20. 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)

21. 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 Fax send/receive LDAP server connectivity

22. Unity admin overview Web interface for most tasks

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

24. Unity vs. PhoneMail Multiple interfaces More user customization Web help interface

25. 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
