Joint Statement of Unified Communications Interoperability from Cisco and Microsoft
Direct SIP Interoperability
Microsoft and Cisco jointly tested Direct SIP support between Microsoft Office Communications Server
2007 R2 and version 7.1.3 and 8.0.1 of Cisco Unified Communications Manager2. These are qualified
interoperability scenarios supported by both Cisco and Microsoft.
Microsoft has tested and supports Direct SIP interoperability between Cisco Unified Communications
Manager versions 4.x, 6.x, 7.x and 8.0.3 with Microsoft Lync Server 2010 and Cisco Unified
Communications Manager 4.x and 5.x with Office Communications Server 2007 and Office
Communications Server 2007 R2 as documented on the Microsoft Unified Communications Open
Interoperability Program website1.
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.
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 Portal2. Cisco has not tested Direct SIP interoperability
between Office Communications Server 2007, Office Communications Server 2007 R2, or Microsoft Lync
Server 2010 and Cisco Unified Communications Manager versions 4.x and 5.x.
Microsoft and Cisco are currently testing Direct SIP support between Microsoft Lync Server 2010 and
Cisco Unified Communications Manager version 8.5. When testing is validated (targeting Q3 CY2011),
this will be a qualified interoperability scenario supported by both Cisco and Microsoft.
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.

Cisco UC Integration for Microsoft Office Communicator
Cisco UC Integration for Microsoft Lync
Microsoft provides support for its published APIs for Microsoft Office Communications Server3 and
Microsoft Lync4 to all its ISV partners. Cisco, a Microsoft Gold Certified Partner, used these published
APIs to develop the “Cisco UC Integration for Microsoft Office Communicator” and “Cisco UC Integration
for Microsoft Lync” products. Microsoft is pleased that Cisco has chosen to leverage Microsoft APIs to
provide functionality for our mutual customers as an ISV.
Cisco, as the developer of the “Cisco UC Integration for Microsoft Office Communicator” and “Cisco UC
Integration for Microsoft Lync”, provides support for these products. Microsoft will provide ongoing
support for the published APIs for Microsoft Office Communications Server and Microsoft Lync to our
ISV’s, including Cisco. Microsoft does not provide direct support for either Cisco product. 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 Lync.
As Microsoft’s UC platform capabilities evolve, customer and ISV feedback is actively encouraged
regarding UC platform evolution and announcing changes well in advance of shipping product. In doing
so, Microsoft follows a consistent process that allows lead time for customers and ISVs to make required
changes to their applications that rely on Microsoft software. In addition, Microsoft has specific
technology adopter programs available for ISVs, including Cisco, where Microsoft provides support and
roadmap information to help ISVs effectively build on the UC platform. As a result of these joint
activities, Cisco’s release of the “Cisco UC Integration for Microsoft Lync” product supports both
Microsoft Office Communicator and Microsoft Lync 2010.

Remote Call Control
Microsoft Live Communications Server 2005 SP1, Microsoft Office Communications Server 2007,
Microsoft Office Communications Server 2007 R2 and Microsoft Lync Server 2010 offer an interface to
third-party PBXs based on ECMA TR/875 called Remote Call Control. This capability allows Microsoft
Office Communicator or Microsoft Lync 2010 to control a PBX station set and to have station set
presence reflected in Office Communicator or Lync 2010. Microsoft generically supports the TR/87
interface, without requiring specific PBX vendor or version support.
Cisco supports Remote Call Control between Microsoft Live Communications Server 2005 and Office
Communications Server 2007 and Cisco Unified Communications Manager versions 5.x, 6.x, 7.x and 8.x
via Cisco Unified Presence 6.x, 7.0 and 8.x6. Cisco supports Remote Call Control between Office
Communications Server 2007 R2 and Cisco Unified Communications Manager 7.1.3 and 8.x via Cisco
Unified Presence 7.0.5 and 8.x6. Cisco supports Remote Call Control between Lync Server 2010 and
Cisco Unified Communications Manager 8.x via Cisco Unified Presence 8.5.26.
Remote Call Control is supported by Microsoft in Office Communications Server 2007, Office
Communications Server 2007 R2 and Lync Server 2010.

Video
Microsoft and Cisco provide standards-based video integration between the Microsoft Lync and Office
Communications Server platforms and Cisco TelePresence H.323 and SIP environments.
Acting as a gateway, the Cisco TelePresence Video Communication Server uses a native SIP trunk to
Microsoft Lync and Microsoft Office Communications Server to provide connectivity to a wide range of
standards-based video conferencing devices.
The Cisco TelePresence Video Communication Server can be enhanced with the Cisco TelePresence
Advanced Media Gateway which delivers bidirectional high-definition quality video with Microsoft Lync
and Office Communicator 2007 R2 by transcoding Microsoft’s Real Time Video (RTV) codec into H.264.
Cisco has tested and supports the following video interoperability:
Microsoft Office Communications Server 2007 and Cisco TelePresence Video Communication
Server X4.2 and X5.2
Microsoft Office Communications Server 2007 R2 and Cisco TelePresence Video Communication
Server X4.2 and later
Microsoft Office Communications Server 2007 R2 and Cisco TelePresence Video Communication
Server X5.1.1 and later when including the Cisco TelePresence Advanced Media Gateway
Microsoft Lync Server and Cisco TelePresence Video Communication Server x6.1 and later.
When including the Cisco TelePresence Advanced Media Gateway, version 1.1 or later of the
Cisco TelePresence Advanced Media Gateway is required.
Additionally, Cisco plans to qualify Cisco TelePresence Video Communication Server and Cisco
TelePresence Advanced Media Gateway as supporting the specific functionality included in the
Microsoft video interoperability program. Qualification with both Microsoft Office Communications
Server 2007 R2 and Microsoft Lync is planned.
Microsoft supports any client tested against Office Communications Server 2007 R2 connecting to
Microsoft Lync with the Office Communications Server 2007 R2 level of functionality.
