MAXCS ACM 6.5 Administration Manual
Description
Disables Exchange integration.
Allows a two-way synchronization between a user's MAXCS
voice mail and the user's Outlook-readable mail messages
with their attached .wav files in the user's inbox. When e-mails
or voice mails are deleted from one server, they are
automatically deleted from the other server as well. (This is
what AltiGen's previous releases have offered.)
If you select this option, enter the DNS name of the Exchange
server in the Exchange 2003/2007 Client Access Server
field (do not enter the IP address).
Through bridged access integration, via a SIP connection,
AltiGen's Voice Mail System provides an option to the user to
directly access Exchange Unified Messaging (by pressing 7 in
extension voice mail after entering the password). Once
connected, users can check and reply to e-mail, manage
calendars, and send messages.
Note: If Exchange server is offline or down, the user pressing
7 will hear an error message, "This voice mailbox is not
accepting new messages at this time." All other VM features
still function, as they are provided by the MAXCS system and
not Exchange server.
If you select this option, enter the DNS name of the Exchange
server in the Exchange 2007 Unified Messaging Server
field (do not enter the IP address).
If you want to synchronize voice mail between the AltiGen mail
box and the Exchange server, check the Enable
Synchronization check box. If you don't check this, voice
mail is not synchronized between the two message stores.
