Cisco Unified Presence supports interdomain federation over the SIP protocol with the AOL SIP Access Gateway (SAG). SIP federation with AOL enables Cisco Unified Presence users to federate with the following users: users with AOL public communities, for example, aim.com, aol.com, users of an enterprise whose domain is hosted by AOL, users of a foreign enterprise that federates with AOL, Cisco Unified Presence could use AOL as a clearing house to federate with these foreign enterprises.
Standards-based SIP or SIMPLE network interface
Cisco Unified Presence provides a standards-based peering environment to any SIP- or SIMPLE-capable application or network. In effect, any user status that is maintained in the presence engine can be requested using the IETF standards for status and presence sharing. These SIP and SIMPLE standards define the accepted messaging to initiate and maintain a status request and to provide appropriate responses. Status information can be collected and distributed by the presence engine, depending on the needs of the services deployed.
Cisco unified applications environment interface
The Cisco Unified Applications Environment provides a mechanism to allow customers to rapidly create and deploy custom IP phone applications without the complexity associated with programming languages or interfaces. Applications developed in the Cisco Unified Applications Environment can read and write user reachability, device availability, and user status to and from the presence engine.
