Configuring SIP Settings for Integration with Microsoft Servers

Integration with Microsoft servers allows Skype for Business 2015, Lync 2013, and Polycom RealPresence Group system users to place audio and video calls to each other.

Because Polycom RealPresence ITP systems run in dynamic management mode, they cannot be simultaneously registered with Lync Server and the presence service provided by the Polycom RealPresence Resource Manager system.

RealPresence ITP systems can obtain presence services from only one source: Lync Server, or the presence service provided by the RealPresence Resource Manager system. Polycom supports the following features in Microsoft Lync Server 2013 and Skype for Business Server 2015:
  • Interactive Connectivity Establishment (ICE)

  • Centralized Conferencing Control Protocol (CCCP); this feature is available only with the optional license key

  • Federated presence

  • The Microsoft real-time video (RTV) codec; this feature is available only with the optional license key

For more information about this and other Microsoft/Polycom interoperability considerations, refer to the Polycom Unified Communications for Microsoft Environments Solution Deployment Guide.

If your organization deploys multiple Lync Server pools, a Polycom RealPresence ITP system must be registered to the same pool to which the system's user account is assigned.
