Overview of work to dateOverview of work to date
Initial setup and testing “sandbox”MFS deployment drove:– Deployment on VLAN245 (on 6509s,
3524s, and 5500s)CM upgradesVarious equipment testsUnified Messaging (Cisco Unity)
server setup/testing
Marshall Field Site (MFS)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:
MFS – lessons learnedMFS – 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!
IP Phones testedIP 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

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
Unified Messaging (UM)Unified Messaging (UM) – what is it? – 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
UM benefits:UM benefits:
centralized communications controlbrowser-based administrationdecentralized routine administrationscalable, redundant, fault-tolerant
system tools
Cisco Unity overview: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
Cisco Unity: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)
Unity user interface overviewUnity 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
VM replacement issuesVM 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

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