12 Communications Server 1000 with Microsoft Exchange Server 2007 Unified Messaging
automatically result in load sharing of access to Microsoft Exchange
Unified Messaging services by users in the network.
Operational Considerations
Considerations specific to Microsoft Exchange Server 2007 are as follows:
• The only supported codecs are G711 and G723.
• RFC2833 is required for DTMF digit transmission to the Exchange
Server.
•
Exchange Server 2007 must always be configured as a static endpoint
on the NRS as Registration is not supported.
•
The Fax on UM capability is supported.
• Geomant Message Waiting Indicator (MWI) 2007 is a required add-on
for MWI functionality.
• Microsoft Outlook 2007 is required.
•
Exchange Server 2007 requires the use of x64 processors.
•
For the Play on Phone option to function, the default Outlook data file
used must be of type .ost. If the default Outlook data file is of type
.pst, the Play on Phone option will not be available.
•
Calling a non-Exchange user using the Auto Attendant functionality is
not supported by Microsoft Exchange Unified Messaging.
• Due to known issue concerning support of Payload 101 for RFC2833,
intermittent DTMF issues will be experienced with PC-based clients.
• Interoperability with BCM/SRG and CS 2100 over H.323 causes
speech path issues due to non-handling of RE-INVITE requests by
Microsoft Exchange Unified Messaging Server.
Considerations specific to the Geomant MWI Application are as follows:
•
In a Main Office-Branch Office (MO-BO) environment, MWI
functionality is provided in either Normal or Local mode, as MWI is not
supported as multiple instances in the same domain.
•
In a Geographic Redundant System environment, MWI functionality
is provided in either a Primary Call Server (PCS) or a Secondary Call
Server (SCS) system, as MWI is not supported as multiple instances
in the same domain
Considerations specific to the Communication Server 1000 are as follows:
• Only CDP dialing is supported between the home CS 1000 and the
UM Server - users dial in to the home CS 1000 using any configured
