Internet Messaging for the INTUITY
AUDIX builds on the multimedia capabilities of INTUITY AUDIX to provide
exchange of voice, text, fax, and binary components over the Internet.
Topics include:
Internet
Messaging Features
Internet Messaging has the following
characteristics:
- Internet Gateway
AUDIX subscribers gain
access to an Internet email address and can send or receive messages
over the Internet. Internet Messaging uses Extended Simple Mail Transport
Protocol (ESMTP), a standard TCP/IP-based mail protocol.
- Mailbox access through
POP3 clients
In addition to the telephone
user interface (TUI) and INTUITY Message Manager 4.3 and later, subscribers
can also select one of the currently available POP3 email client programs
to check their messages. For example, Netscape Mail or Microsoft Outlook
can be used to receive and respond to messages through the INTUITY
AUDIX server.
- Avaya Voice Player
With this player, Internet
email users can play and respond to messages received from INTUITY
AUDIX senders. If a subscriber has a microphone, the subscriber can
create voice messages directly on his or herpersonal computer.
What
Internet Messaging Can Do for You
Internet Messaging can:
- Provide access for INTUITY
AUDIX subscribers to any of the email users worldwide through the
Internet.
- Increase the number of
choices that subscribers have to access messages, including telephone,
INTUITY Message Manager, and industry-standard email platforms.
- Save costs by allowing
message transport through existing, shared Internet facilities.
- Simplify distribution of
the Voice Player through an automatic email response system.
Sending and Receiving Email
Internet Messaging gives INTUITY
Message Manager and Post Office Protocol 3 (POP3) client subscribers
full Internet email capabilities through the INTUITY AUDIX. Multimedia
messages can be sent from the INTUITY AUDIX to any email address. The
recipients can access these messages as multipart MIME messages using
commercially available email software. Voice components are played with
the Avaya Voice Player (AVP), which is distributed without charge and
uses the same voice compression algorithm as the INTUITY AUDIX system.
Email Access With Computer
Applications
The following access methods are
available:
- Message Manager subscribers
can send and receive all four component types to and from Internet
email users, as with any other INTUITY AUDIX destination. These component
types include voice, fax, text, and file attachments.
- POP3 client subscribers
can use their browser to access their INTUITY AUDIX mailboxes. The
AVP plays and records voice components, with the appropriate computer
hardware configuration. Graphics programs display fax files. Text
and attached files are handled as with any other email.
- Non-INTUITY AUDIX users
access messages by using the same message-rendering tools as POP3
client subscribers, except that the messages are delivered through
their own Internet service provider.
Email Access Through the Telephone
With Internet Messaging for INTUITY
AUDIX, subscribers can use the telephone to manage messages received
at their AUDIX mailbox. The message-waiting indicator (MWI, such as
the indicator lamp or a stutter dial tone) is activated to alert a subscriber
to the arrival of new messages.
The message can contain up to
three media types, specifically voice, text, and file attachments. (If
a fax is contained in the message, the system notifies the subscriber
that the fax component is unaccessible.) From the telephone, subscribers
can:
- Receive an email message
that can contain up to three media type components.
- Listen to a voiced rendering
of the text component (if the INTUITY AUDIX Text-to-Speech feature
is activated).
- Reply to an email message,
whether it came from an INTUITY AUDIX subscriber or an Internet email
address.
A message is treated as a single
entity when accessed through a telephone. When subscribers play a message
that contains a voice, a text message, and a file attachment component,
they hear the following:
- The voice component
- The spoken translation of the text component
(if enabled)
- A voiced summary about the attached file
Optional Email Features
Text-to-Speech (TTS) conversion is an optional feature
that enables subscribers to listen to a voiced rendering of email and
INTUITY Message Manager text messages received in their AUDIX mailboxes.
Message components are rendered as follows:
- The subject line of an email message is read
as part of the message header.
- The body of the text message is voiced.
- If a file attachment is included in the email
message, that component is not voiced. The subscriber hears summary
information with regard to the size of the file.
Planning
Before you install Internet Messaging,
there are several things that you need to consider:
Email Message Size
Email messaging can have a significant
impact on the size set for a subscriber's mailbox. An email message
can be a short memo or can include attachments of software files of
considerable size. If subscribers send fax and voice messages, planning
is more difficult.
AUDIX converts all message components
into seconds of space in the mailbox. A mailbox can have up to 1800
seconds of recorded voice messages, which is approximately 2.4 MB. Attached
files through Internet Messaging could fill up a mailbox very quickly.
LAN Impact
Use the following table to estimate
how much of the LAN traffic on the system will be comprised of email
messages (including email with attached components).
Table: LAN Impact of Email Messaging
| Component |
Size |
| Voice |
60 seconds = 132 1-KB packets |
| Email |
5 KB = 5.5 1-KB packets |
|
Attachments, including email attachments
|
Approximately 150 KB (file size varies by
type of file and contents)
|
Subscriber Planning
Prepare subscribers by taking the
following steps:
- Inform users about their INTUITY AUDIX email capabilities. See Notifying
Subscribers of Email Capability and Setup for more information.
- Allow INTUITY Message Manager subscribers to add email addresses
to their personal address books or their INTUITY AUDIX lists to simplify
addressing.
- Determine whether to allow INTUITY AUDIX subscribers to access messages
in their INTUITY AUDIX mailbox with a POP3 email program. The INTUITY
AUDIX system can send messages similar to any mail gateway, but allowing
this access presents certain security risks. See Security
Issues for more information.
- When questions arise, or during the initial training about INTUITY
AUDIX email, describe the following differences to subscribers:
- When a message is sent from an AUDIX subscriber to recipients
in both AUDIX and the Internet, the AUDIX recipients are not listed
on the Internet recipient's email To: list. Therefore, the email
recipients do not know which AUDIX subscribers also received the
message and cannot use the email application's Reply All function
to send a reply to the AUDIX recipients of the original message.
- INTUITY AUDIX messages expire within a time period determined
by the subscriber or COS mailbox settings. Subscribers need to
understand this difference because email accounts do not usually
have this limitation.
- Users can set their email application (such as Outlook or Exchange)
to forward mail automatically to another email address or to their
INTUITY AUDIX email address. INTUITY AUDIX does not allow mail
to be automatically forwarded to another email address.
Security
Issues

Toll fraud is the theft of long distance service. When toll fraud
occurs, your company is responsible for charges. See Overview
of Security for information on how to prevent toll
fraud or call the Avaya National Customer Care Center at 1-800-643-2353.

The use of Internet Messaging
and the Internet presents certain security issues. Your company is responsible
for any damages that could arise as a result of the use of Internet
Messaging. However, you can administer your system to minimize these
risks. You need to be concerned with:
Disabling POP3 Access
On the General Options and Settings page, if
the POP3 enabled? field is set to Yes, hackers could
determine a subscriber's login name and password and then commit toll
fraud through the subscriber's mailbox. Use Internet Messaging only
behind a corporate firewall and restrict external Internet access to
the POP3 port.
If your company is concerned with subscriber
login security, consider the following alternatives:
- Disable the POP3 interface by selecting No on the General
Options and Settings page.
- Exclusively use POP3 clients such as Qualcomm's Eudora
client that support the APOP (encrypted password) login mechanism.
- Deploy secure socket layer (SSL) for POP3 by using an external SSL
accelerator. Current products on the market include SSL100 Accelerator
by Avaya.
Viruses
The ease with which messages can be broadcast
and transmitted over the Internet simplifies the distribution of computer
viruses. Enact a policy to ensure that subscribers check incoming messages
and files for viruses.
Another precaution, especially important if this is your company's
first email deployment, is a systemwide virus scanning application.
The applications scan all incoming mail for viruses and intercept
infected mail and files before they reach the subscriber. Current examples
include:
- Interscan Virus Wall by Trend Micro
- Webshield products by McAfee
- Antivirus for Gateways by Norton
- eSafe Gateway by Aladdin
Spoofing or Sending Email
Under a False Name
Internet email addresses are not validated
for identity. As a result, the identity of the message sender is not
guaranteed. Warn your subscribers not to respond to messages from unverified
sources, especially if the message contains requests for private information
or for any form of payment. You can check the name of the machine that
delivered a message to the Internet Messaging server by reading the
message's header information.
