Unified Messaging (UM)

Feature Description

Feature Description
When installed, the Stratagy ES exists as a peer Simple Message Transport Protocol (SMTP) server
on a network along with the e-mail server. When new voice messages arrive, the voice mail
generates an e-mail message that is sent to the e-mail server using the SMTP standard. The actual
content of the message is dependent on the UM integration scheme that is in use (see
Outlook Integration" on page 7-4
When the user logs in to his/her e-mail account, the voice messages display in that e-mail inbox.
To communicate with an e-mail server, the voice mail uses Internet Message Access Protocol
Version 4 (IMAP4), SMTP, or POP3 Internet standards. By integrating solely on the principles of
these standards, the voice mail can incorporate a UM solution with any e-mail server that supports
these same standards. In this day and age of the Internet, most e-mail server products, from
Microsoft Exchange to inexpensive shareware software, is compliant to these Internet standards.

Voice File Compression

Voice messages are transported to the e-mail client as .wav files. A .wav file consists of a voice file
with a header attachment that defines the voice compression algorithm that was used to record the
voice file.
Unified Messaging sends voice files with the same low frequency compression algorithm that is
used to store voice messages on the system's hard drive. By default this compression algorithm is
Adaptive Delta Pulse Code Modulation (ADPCM) 32K or 4 bit x 8 kilohertz.
Using a low compression algorithm means that the bandwidth of the network should not be
adversely affected by the periodic transport of these .wav files. For example, a voice message
lasting one minute, which is double the time of an average message, creates a voice file just under
250K. Voice File compression can be changed using the sys_msg_recording_audio_type
parameter.

UM Synchronization

UM synchronization uses IMAP4 to provide users a synchronized message set (of voice messages)
both in their SES mailbox and in the e-mail server mailbox. When new voice messages are received,
Stratagy sends the referenced message (or the WAV file with the Internet Protocol Integration
method for UM) via SMTP to the e-mail server with a special identifier in the message.
This feature must be programmed in the Mailbox Editor, Unified Messaging tab screen.

IMAP4

When you select IMAP4 on the Unified Messaging screen, the following occurs:
•
If a user logs into his/her voice mail via the TUI and deletes a message, Stratagy uses IMAP to
identify and delete the message in the e-mail server. This also deletes the messages from the
user's e-mail client inbox screen if the messages were displayed on it at the time.
If a user logs into his/her voice mail via the TUI and listens to a message in the NEW folder, the
corresponding message in the e-mail server or e-mail client inbox is flagged as "read" or
"seen." This includes messages that are marked by Stratagy as Pending and kept in the New
Message folder. Messages marked as Deleted are not actually deleted until the user logs out
from his or her UM-enabled mailbox.
