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

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 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 calllegs (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 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
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)
Call Manager Admin Interface
Compaq Proliant DL380 server
 Windows 2000 Server
 Internet Information Server 5
 Cisco Call Manager

VoIP vs. traditional PBX

What’s the difference?
System Administration
System Administration
System Redundancy
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
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
UM benefits:
centralized communications control
 browser-based administration
 decentralized routine administration
 scalable, redundant, fault-tolerant
system tools

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:

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 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
Unity admin overview

Web interface for most tasks
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

Unity vs. PhoneMail
Multiple interfaces
 More user customization
 Web help interface

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

