Basic Federated Network
This integration enables the IM and Presence Service users in one enterprise domain to exchange presence information and Instant Messaging (IM) with users in external domains. The IM and Presence Service uses different protocols to federate with different external domains.
The IM and Presence Service uses the standard Session Initiation Protocol (SIP RFC 3261) to federate with:
• Microsoft Office Communications Server Release 2 (OCS R2), OCS 2007, Microsoft Lync 2010
Note
IM and Presence Service Release 9.0 or later supports interdomain federation with Microsoft Lync. For IM and Presence Service Release 9.0 or later, any reference to interdomain federation with OCS also includes Microsoft Lync, unless explicitly stated otherwise.
• AOL SIP Access Gateway (SAG)
Note
IM and Presence Service Release 9.0 or later supports interdomain federation with AOL.
SIP federation with AOL enables IM and Presence Service users to federate with the following users:
• Users of AOL public communities, for example, aim.com, aol.com.
• Users of an enterprise whose domain is hosted by AOL.
• Users of an external enterprise that federate with AOL. IM and Presence Service could use AOL as a clearing house to federate with these external enterprises.
IM and Presence Service uses the Extensible Messaging and Presence Protocol (XMPP) to federate with:
• IBM Sametime Server 8.2 and 8.5
• Cisco Webex Connect Release 6
• Cisco Unified Presence Release 8.x
• Any other server that is XMPP Standards compliant
• IM and Presence Service does not support federation between an IM and Presence Service Release 9.0 enterprise, and a Cisco Unified Presence Release 7.0(x) enterprise.
