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.
