The following are considerations related to Unified Messenger SMTP/MIME
remote machines.
There are several known considerations when using SMTP/MIME as
the message delivery mechanism to Unified Messenger with Microsoft
Exchange or Lotus Notes:
- Voiced name: For Unified Messenger subscribers, the remote
subscribers on the Message Networking system have a text-to-speech
name rather than the self-recorded voiced name.
- No blind addressing: When numerically addressing a Message
Networking recipient, that recipient must be preadministered as
a remote subscriber on the UM/Exchange or UM/Lotus Notes system.
- Manual directory initialization: On Unified Messenger
systems (with either Microsoft Exchange or Lotus Notes), SMTP/MIME
provides the message transport between the Message Networking
system and the Unified Messenger. However, SMTP/MIME does not
inherently provide automatic subscriber directory updates. Message
Networking requires the directory entries to perform a mapping
between the unique numeric Network Address (often the phone number)
and the email address of the Unified Messenger subscriber (for
example, 303-555-1234 is [email protected]).
In addition, each subscriber residing on a system supported one
of the other protocols supported by Message Networking also has
a unique numeric Network Address and an email address (for example,
303-555-6789 is [email protected]). The
Unified Messenger application requires the directory entries to
map between the numeric Network Address and the email address
of the Message Networking recipient.
Because the subscriber directory updates are not automatically
provided, the directory entries that map a Network Address and
ASCII name to a Message Networking email address must be manually
populated. There is a manual process that you can use to extract
the directory from Message Networking and import it into the Exchange
or Lotus directory. The UM subscriber records on the Message Networking
side must also be built manually using one of the following methods:
- Bulk Adding the Subscribers by File: Use FTP to import
a file into the Message Networking system that contains the
numeric network address and email address.
- Self-Registration: Have each UM subscriber self-register
on the Message Networking system by sending a voice name as
a message and the network address in the Subject field to
a predefined self-registration mailbox.
- Subscriber Administration: Have a Message Networking administrator
administer each UM subscriber on the Message Networking system
using the administration interface.
- No Directory Updates: On the UM for Exchange or UM for
Lotus Notes system, there are no ongoing directory updates (ASCII
name or voiced name). On the Message Networking system, only the
ASCII name is updated.
- Voice message is email (MS Exchange only): When a voice
message is sent to a UM/Exchange system, it is treated as an email
message (that is, a .wav file binary attachment) rather than a
voice message.
- On UM for Lotus Notes Release 5.0 or later systems, remote subscribers
must be administered as users on
the Lotus Notes/Domino system. This allows subscribers on
the local UM for Lotus Notes system to send TUI messages to remote
subscribers via Message Networking.
- On UM for Exchange systems, remote subscribers must be administered
as users on the Exchange system. This allows subscribers on
the local UM for Exchange system to send TUI messages to remote
subscribers via Message Networking.
Unified Messenger, with either Microsoft Exchange or Lotus Notes,
uses the GSM voice encoding format. The actual SMTP/MIME communication
is between the Message Networking system and the message storage
server (Microsoft Exchange or Lotus Domino).
- Message Networking currently does not recognize faxes that are
part of message replies or forwards because of the way that Lotus
Notes designates this type of faxes and treats the faxes as binary
attachments. Binary attachments are stripped on remote machines
that do not handle binary attachments.
