Cisco UC IntegrationÔ for Microsoft Office Communicator
Microsoft provides support for its published APIs[1] for Microsoft Office Communications Server and Microsoft Office Communicator to all its ISV partners. Cisco, a Microsoft Gold Certified Partner, uses these published APIs to develop the Cisco UC IntegrationÔ for Microsoft Office Communicator product. Microsoft is pleased that Cisco has chosen to leverage Microsoft API’s to provide functionality for our mutual customers as an ISV.
Cisco, as the developer of the Cisco UC IntegrationÔ for Microsoft Office Communicator, provides support for this product. Microsoft will provide ongoing support for the published APIs for Microsoft Office Communications Server and Microsoft Office Communicator to our ISV’s, including Cisco. Microsoft does not provide direct support for the Cisco UC IntegrationÔ for Microsoft Office Communicator. The Microsoft UC platform will continue to evolve as the industry evolves and customer requirements change, and as with our broader ISV community, Microsoft is fully committed to working with Cisco so they can provide quality support for our mutual customers with future versions of Microsoft Office Communications Server and Office Communicator.
Remote Call Control is supported by Microsoft in Office Communications Server 2007 and Office Communications Server 2007 R2 and will continue to be supported for customers upgrading their Remote Call Control deployments to the next release of Office Communications Server. Microsoft has announced the deprecation of Remote Call Control in Office Communications Server. As a result, in the next release of Office Communications Server, new deployments of Remote Call Control will not be supported by Microsoft.
Direct SIP Interoperability
Microsoft has tested and supports Direct SIP interoperability between Cisco Unified Communications Manager versions 4.x and 5.x and Office Communications Server 2007 and Office Communications Server 2007 R2, as documented on the Microsoft Unified Communications Open Interoperability Program website. While Cisco offers and supports a SIP interface with Cisco Unified Communications Manager versions 4.x and 5.x, interoperability using this interface is only supported for systems that have been tested and documented on the Cisco Interoperability Portal. Cisco has not tested Direct SIP interoperability between Office Communications Server 2007 and Office Communications Server 2007 R2 and Cisco Unified Communications Manager versions 4.x and 5.x.
Cisco has tested and supports Direct SIP interoperability between Microsoft Office Communications Server 2007 and Cisco Unified Communications Manager versions 6.1 and 7.02. Microsoft has tested and supports Office Communications Server 2007 and Office Communications Server 2007 R2 with Cisco Unified Communications Manager version 6.11.
To facilitate interoperability support for our joint customers, both Cisco and Microsoft are members of TSANet, an independent third-party organization that helps coordinate multi-vendor support.
