Love them or hate them, voice messaging systems
are a necessary communications medium that are often stuck in a telecom
closet and forgotten about until problems (such as overfilled voice
mailboxes, break-in attempts, full hard disk space, etc.) crop up. Many
voice messaging systems only have a cryptic command line interface (CLI)
requiring a telnet session, serial connection, or modem dialup. These CLIs
are not very user-friendly, making telecom managers and IT personnel
hesitant to manage the voice mail system on a day-to-day basis. For large
enterprises with multiple voice messaging systems in multiple locations to
administer, the telecom manager's headaches only get worse.
Fortunately, Vitel Software's VMACS-Plus comes to the rescue for those
owning one or more Lucent Technologies messaging platforms, such as AUDIX,
DEFINITY AUDIX, and INTUITY AUDIX. Featuring a Windows graphical user
interface, VMACS-Plus is a management tools, that can effectively manage
multiple voice messaging systems. By automatically retrieving data from
one or more systems into a centralized database, VMACS-Plus can organize
and store information and then provide centralized reporting, including
graphs and statistics for the entire enterprise.
For our testing purposes, TMC Labs decided it was best to see the
software "in action" at a customer site. After talking with
Vitel Software, we decided that the Museum of Modern Art in New York City
was a good candidate. It was only a short train ride into the city from
our lab, and we could expand our artistic horizons after testing the
product.
INSTALLATION
Since the system we examined was a "live" system used in the
Museum of Modern Art, we couldn't uninstall the software and reinstall it
to check out the ease of installation. The customer told us that it was as
simple as inserting a CD, installing the software, configuring the
connection (serial/COM port, modem), dialing into the phone number for
modem connections, and then configuring various options, such as the
polling schedule. However, because we ourselves did not perform an
installation, we didn't rate it. Hopefully the customer's experience gives
you an idea of the installation process.
DOCUMENTATION
The documentation was very good. We had a copy of the Acrobat file, which
was tabulated into eleven chapters, an appendix, and an index. Simply by
clicking on any of the chapter headings, we were able to skip ahead in the
electronic documentation. Of course for those that prefer the "touch
and feel" of a printed copy, the Acrobat file is certainly printable.
We examined the manual and found it very readable and well organized.
Screenshots were plentiful, and "helpful hints" in special gray
call-out boxes were also available.
FEATURES
The VMACS-Plus features on-screen view forms with extensive filtering
and sorting capability. Using this software you can identify break-in
attempts, perform system audits, report on active alarms, port usage, call
volumes, disk usage, and more. In addition, you can report on the system
auto-attendant to determine which IVR trees are "hit" the most
and where people get stuck and "zero out" to the operator. Using
this information can be incredibly valuable when redesigning the IVR/auto-attendant
to improve customer service and satisfaction. Also, as previously
mentioned, VMACS-Plus currently supports several Lucent messaging
platforms, including AUDIX, DEFINITY AUDIX, and INTUITY AUDIX.
Over 80 reports and graphs are available. Here are a few of the more
interesting ones:
- Voice mail directory by name -- useful for printing out corporate
directories.
- Full mailbox -- reports on full mailboxes.
- Subscriber list by COS -- reports on all subscribers and their
assigned Class of Service.
- Feature day summary -- summary totals for selected traffic
categories for each day.
- Subscriber disk usage -- displays users using the most disk space.
- Charges by cost center (optional module) -- depicts charge back
totals for each extension in a cost center for accountability.
Other features include SMTP (e-mail) alerting, traffic statistics,
scheduled polling of data off of voice messaging system(s), reporting on
fax, and batch scheduling of reports to run.
OPERATIONAL TESTING
When we arrived at the Museum of Modern Art, we were greeted outside
by picketing employees who were on strike. Interestingly enough, the fact
that union employees of the Museum of Modern Art were on strike actually
was relevant to our testing process. The telecom manager who managed their
auto-attendant/voice mail system told us that the VMACS-Plus system
actually detected a "spike" in the number of break-in attempts
into the voice messaging system during the strike. After several failed
password attempts, that particular voice mailbox is locked out, which
prevents a temporary employee from checking any voice messages.
Fortunately, with VMACS-Plus installed (along with its alerting
capabilities), the telecom manager was able to proactively unlock voice
mail boxes as well as change passwords.
In any event, we proceeded to test the VMACS-Plus by first examining
how the system is configured to work with an existing voice messaging
system in place. The software communicates with the Lucent voice messaging
system (Intuity in this case) via a serial connection through a PC's
serial port, but can also dial into Intuity's internal modem for
communication. Currently displayed in this figure is the voice mail form
screen for defining modem parameters, password, phone number, and other
settings.
The system can be configured to automatically "pull" data
from one or more voice messaging systems at scheduled intervals (daily,
weekly, etc.). Since there was already some existing data
"pulled" into the VMACS-Plus database, we proceeded to run some
sample reports. When executing reports you can create filters to sift out
unneeded information. We were pleased to find that creating filters was
very easy to do.
The VMACS-Plus features a built-in Telnet client, which allowed us to
connect to the Intuity system if we desired. Another useful feature was
the "batch scheduling" of reports to run. You can schedule a
report to execute when network traffic is low, such as late at night. Then
the report(s) will be waiting for you first thing in morning. We could
change the sort order (ascending/descending) and sort by many various
fields, such as COS, subscriber, name, extension, and more -- this sort
feature is a nice touch in our book.
TMC Labs determined that with just a small learning curve we could use
the VMACS-Plus system to perform trend analysis, capacity management,
system monitoring, and forecasting. Forecasting is important for answering
such questions as "Will I need to add more voice ports soon?"
and "When will I run out of disk space?" Overall, we were very
pleased with our tests and didn't find any glaring bugs or flaws with the
product, though we did have some suggestions.
ROOM FOR IMPROVEMENT
We'd like to suggest the option of a Web-based interface so telecom
managers can administer the system and look at reports anywhere they have
an IP connection. Also, concerning usability when running reports: -- we'd
like to be able to double-click on a report to execute it. Currently,
users can't do this. Instead you must go to the "Report Details"
tab, which we found to be a bit of a nuisance due to the extra mouse
clicks required. One other minor usability issue is that you have to close
any open windows before you can execute another command, such as running a
report.
Although the report printouts are quite readable with the fixed font,
we'd like the option of choosing a font, as well as font size. Although
creating powerful filters is very easy in VMACS-Plus, we know that often
techno-savvy IT personnel want to write their own SQL queries. We
determined that the current version did not support SQL queries. We
inquired if VMACS-Plus was going to add SQL functionality and were told
this would be in the next release.
CONCLUSION
TMC Labs was impressed with the VMACS-Plus's extensive number of
built-in reports and ease of use. We were able to quickly figure out how
to navigate through the software without having to refer to a manual.
Those looking for a Windows-based voice mail management solution for their
Lucent voice messaging system should seriously consider VMACS-Plus.
