Describe Cisco Unified Presence Architecture
CUPS is a standards-based application that uses several protocols to provide functionality
and feature richness:
Key
To p i c
SIP, SIMPLE, and XMPP to provide generic Presence and federation functionality
■
Simple Object Access Protocol (SOAP) to access the CUCM database via Cisco Uni-
fied Communications System XML and CUPC configuration profiles
■
Computer Telephone Interface Quick Buffer Encoding (CTIQBE) for CTI integration
for remote call control with Microsoft Office Communicator
■
HTTP to provide IP Phone Messenger (IPPM) on Cisco IP phones
■
The core components of CUPS are as follows:
Jabber XCP:
Provides Presence, IM, contacts listing, message and call routing, and
policy and federation.
■
Rich Presence service:
Manages Presence state gathering and Presence-enabled
routing.
■
Group chat storage:
Ad-Hoc group chats are normally stored in memory on the
CUPS server; Persistent Chat and message archiving require an external database.
■
Integration with Microsoft Office Communications Server
CUPS interoperates with Microsoft Live Communications Server 2005 or Microsoft Of-
fice Communications Server 2007 using SIP. The Microsoft Office Communicator client
and associated IP phone interoperate to provide click-to-dial, phone control, and Presence
capability.
Integration with LDAP
CUPS can be integrated with Lightweight Directory Access Protocol (LDAP) (including
Microsoft Active Directory), allowing users to log in with their LDAP credentials and
synchronize their Presence status with their Outlook/Exchange calendar. The LDAP
