Overview 13
dialing plan to access services provided by Communications Server
1000 with Microsoft Exchange Server 2007 Unified Messaging.
•
Configuration of the voice mail soft key cannot be changed if there is
a combination of CallPilot and Microsoft Exchange Unified Messaging
voice mail users on a single node. A recommended deployment
solution would be to have CallPilot users and Microsoft Exchange
Unified Messaging users associated with separate Line TPS nodes.
The voice mail soft key feature on the phone set assigns a unique key
to each of the voice messaging functions.
• While operating with an MCS PC Client, Microsoft Exchange Unified
Messaging calls can not be placed on hold.
•
The existing limitation on the NRS of multiple endpoints with the same
static IP address is not supported. This affects network environments
where two CDP domains are configured to use the same Microsoft
Exchange Server 2007.
• The IP Softphone 2050 does not support RFC2833; therefore, it can
not be used with the Subscriber Access and Auto Attendant features of
the Exchange Server 2007.
• If a call originates from an H.323 endpoint (CS 1000/BCM/SRG) and
is tandem transferred by the CS 1000 to the Microsoft Exchange
Unified Messaging Server using SIP, the Subscriber Access and Auto
Attendant feature can only be accessed by voice command and not by
keypad (DTMF), as there is no support for RFC2833 over an H.323
network.
• If the far end does not support RFC2833 (with a payload value of 101),
the Play on Phone functionality is not supported.
• Calls forwarded by Integrated Call Director (ICD) to Microsoft
Exchange Unified Messaging are not supported.
Microsoft Exchange Unified Messaging operational characteristics
•
When a Microsoft Exchange Unified Messaging-enabled user plays
back stored voice mail messages, the order of playback begins
with the last message recorded. That is, when voice mail has been
received (in order) from User 1, User 2, and User 3, the messages are
replayed in the order of User 3, User 2, User 1.
• For a voice mail message that is a reply to an earlier voice mail
message, the reply message is played before the playback of the
original message.
• If there is only one voice mail message waiting for the user, it is not
possible to undelete that voice mail message once it has been deleted.
