  1. Voice over IP (VoIP) and Unified Messaging (UM) - NETS testing updateNETS 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:

  4. 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!

  5. 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

  6. 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)

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

  8. VoIP vs. traditional PBX • What’s the difference?

  9. System Administration

  10. System Administration

  11. System Redundancy

  12. 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

  13. 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

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

  15. 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

  16. 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)

  17. 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

  18. Unity admin overview • Web interface for most tasks

  19. 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

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

  21. 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

  22. Wrap-up • NETS VoIP project page • Cisco 7960 IP Phone tutorial • Questions?
