The Cisco Unified Presence server uses standards-based Session Initiation Protocol (SIP), SIP for Instant Messaging and Presence Leveraging Extensions (SIMPLE), and Extensible Messaging and Presence Protocol (XMPP) to provide a common demarcation point for integrating clients and applications into the Cisco Unified Communications System.

Cisco Unified Presence also provides a HTTP interface that has a configuration interface through Simple Object Access Protocol (SOAP), a presence interface through Representational State Transfer (REST), and a presence, instant messaging, and roster interface through the Cisco AJAX XMPP Library (CAXL). CAXL communicates to the Bidirectional-streams Over Synchronous HTTP (BOSH) interface on the Extensible Communications Platform within Cisco Unified Presence.

The Cisco Unified Presence server collects, aggregates, and distributes user capabilities and attributes using these standards-based SIP/SIMPLE, XMPP, BOSH, SOAP, and REST interfaces.

Session Initiation Protocol (SIP) and SIP for Instant Messaging and Presence Leveraging Extensions (SIMPLE)

The SIP/SIMPLE based interfaces for Cisco Unified Presence provide the following functionality:

• Availability (PUBLISH, SUBSCRIBE and NOTIFY interfaces)

• Unified Client Change Notification (UCCN) subscription (SUBSCRIBE and NOTIFY interfaces)

• Instant Messaging (Page mode MESSAGE)

eXtensible Messaging and Presence Protocol (XMPP)

The XMPP Presence and Instant Messaging protocol is the core protocol on Cisco Unified Presence. This interface provides instant messaging, availability and roster management services.

Bidirectional-streams Over Synchronous HTTP (BOSH)

The BOSH interface allows allows integration with instant messaging, availability and roster management services from Cisco Unified Presence into your web-based applications. Cisco provide the Cisco AJAX XMPP Library (CAXL) as a JavaScript based XMPP client library that allows developers to build web applications which utilize the BOSH interface

Client Configuration Web Service (SOAP)

The Client Configuration Web Service is an interface to Cisco Unified Presence that allows client applications to manage user preference information such as contacts, presence rules, access control lists, and calendaring options. This web service is available via a Simple Object Access Protocol (SOAP) interface.

Presence Web Service (SOAP/REST)

The Presence Web Service is an open interface that allows client applications to share user presence information with Cisco Unified Presence. This interface is used by developers to build client applications that can send and receive user presence state updates. The web service is available via a SOAP interface and a REST (HTTP/XML) interface.

Platform SOAP Service (SOAP)

The Platform SOAP Services facilitate upgrades and install of COP file for large scale deployments of Cisco Unified Presence, to be initiated and monitored from a single management client. This service provides a web-based SOAP interface integrated with the existing upgrade framework.

Open APIs

SIP for Instant Messaging and Presence Leveraging Extensions (SIMPLE) (CUP 1+)

Simple Object Access Protocol (SOAP) (CUP 7+)

Representational State Transfer (REST) (CUP 7+)

Extensible Messaging and Presence Protocol (XMPP) (CUP 8+)

Bidirectional Streams over Synchronous HTTP (BOSH) (CUP 8+)

Compliance (CUP 8+)

The options are using an ODBC-based external database connection for message archiving using native Jabber components or the customer deploying a FaceTime server which connects to CUP through the XDB interface.

High Availability (CUP 7+, CUP 8.5.1+, but not CUP 8.0.x)

Allows for users on one Cisco Unified Presence node within a subcluster to automatically fail-over to the other node within the subcluster.

Clustering over WAN (CUP 7.0.5, CUP 8.5.1+, but not CUP 8.0.x)

A Cisco Unified Presence cluster can be deployed with one of the nodes of a subcluster deployed across the Wide Area Network (WAN). This allows for geographic redundancy of a subcluster and high availability for the users between the nodes across the sites.

File Transfer (CUP 8+)

Peer to Peer mode of file transfer using out of band signaling (SOCKS5).

Supports file transfer for XMPP clients only. File transfer to chat rooms is not supported.

No File Transfer Proxy is supported so transfers to clients behind a firewall (including federated clients) is not supported.
