On November 30, you will be able to download Exchange Server 2007 with Service Pack 1. The list of new features in SP1 is long, including new deployment options, new features and improvements for each server role, improved integration with other applications, and even a new, third type of continuous replication. There are also general updates to almost all of the high availability topics for SP1, as well as significant updates in other content areas, such as those related to the Mailbox, Client Access, Hub Transport and Edge Transport, and the Unified Messaging server roles. You can find documentation on the new features by browsing or searching the Exchange Server TechCenter Library. If you're in evaluation mode, you can now download the Exchange Server 2007 with Service Pack 1 trial software and see how secure, anywhere access can enhance operational efficiency.

Unified Messaging has been improved and has added new features in Exchange 2007 SP1. To use some of these features, you must correctly deploy Microsoft Office Communications Server 2007 in your environment.

To correctly plan and deploy Exchange 2007 SP1 and Communications Server 2007 in your Unified Messaging environment, you must follow the planning and deployment steps that are provided in the

Office Communications Server and Client Documentation Rollup.

The following is a summary of the Unified Messaging features that are available in an integrated Exchange 2007 SP1 and Communications Server 2007 environment:

• Ability to create SIP URI and E.164 dial plans by using the New Dial Plan wizard
• Additional logic for resolving internal calling number
• Notification of forwarding when leaving voice messages in scenarios where the destination uses call forwarding
• Support for recording high-fidelity voice messages in Exchange Unified Messaging
• Access to Outlook Voice Access from Microsoft Office Communicator 2007 without requiring the user to enter a PIN
• Ability for Office Communicator 2007 clients to associate subjects and priorities to voice messages
• Support for media streams to traverse firewalls
• Integration of missed call notification e-mail messages with Office Communicator 2007
• Ability to prohibit Play on Phone calls that are placed by using Office Communicator 2007 from being subjected to call forwarding rules that are configured

The following features are available in Exchange 2007 SP1 without integrating your Unified Messaging environment together with Communications Server 2007:

• Support for Secure Realtime Transport Protocol (SRTP).
• Exchange Management Console support for configuring Mutual Transport Layer Security (mutual TLS) for dial plans.
• Ability to add a SIP or E.164 address for a user by using the Enable Unified Messaging Wizard.
• Ability to modify extension numbers and SIP and E.164 addresses for a UM-enabled user by using the Exchange Management Console.
• In-band fax tone detection. By default, this feature is disabled but can be enabled in environments that use IP PBXs.
• Quality of Service (QoS) support.
