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)

4 analog lines on FXS ports on a Cisco 3640

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

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

Web interface for most tasks

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
