Overview of a basic integration

IM and Presence interfaces

Main components

The following figure provides an overview of an IM and Presence deployment, including the main components and interfaces between Cisco Unified Communications Manager and IM and Presence and between IM and Presence and third-party products.

Figure 1. IM and Presence Basic Deployment

SIP interface

A SIP connection handles the presence information exchange between Cisco Unified Communications Manager and the IM and Presence service. To enable the SIP connection on Cisco Unified Communications Manager, you must configure a SIP trunk pointing to the IM and Presence server.

On IM and Presence, configuring Cisco Unified Communications Manager as a Presence Gateway will allow IM and Presence to send SIP subscribe messages to Cisco Unified Communications Manager over the SIP trunk.


Note

IM and Presence does not support clients (Cisco clients or third party) connecting to IM and Presence using SIP/SIMPLE interface over TLS. Only a SIP connection over TCP is supported.

Related Information

CTI interface

The CTI (Computer Telephony Integration) interface handles all the CTI communication for users on the IM and Presence server to control phones on Cisco Unified Communications Manager. The CTI functionality allows users of the Cisco Unified Personal Communicator client to run the application in desk phone control mode.

The CTI functionality is also used for the IM and Presence remote call control feature on the Microsoft Office Communicator client. For information about configuring the remote call control feature, see the Microsoft Office Communicator Call Control with Microsoft OCS for IM and Presence Service on Cisco Unified Communications Manager.

To configure CTI functionality for IM and Presence users on Cisco Unified Communications Manager, users must be associated with a CTI-enabled group, and the primary extension assigned to that user must be enabled for CTI.

To configure Cisco Unified Personal Communicator desk phone control, you must configure a CTI server and profile on IM and Presence, and assign any users that wish to use the application in desk phone mode to that profile. However, note that all CTI communication occurs directly between Cisco Unified Communications Manager and Cisco Unified Personal Communicator, and not through the IM and Presence server.

AXL/SOAP interface

The AXL/SOAP interface handles the database synchronization from Cisco Unified Communications Manager and populates the IM and Presence Service database. To activate the database synchronization, the Sync Agent service must be running on IM and Presence.

By default the Sync Agent load balances all users equally across all nodes within the IM and Presence cluster. You also have the option to manually assign users to a particular node in the IM and Presence cluster.

For guidelines on the recommended synchronization intervals when executing a database synchronization with Cisco Unified Communications Manager, for single and dual-node IM and Presence, see the IM and Presence SRND document.

LDAP interface

Cisco Unified Communications Manager obtains all user information via manual configuration or synchronization directly over LDAP. The IM and Presence Service then synchronizes all this user information from Cisco Unified Communications Manager (using the AXL/SOAP interface).

IM and Presence provides LDAP authentication for users of the Cisco Unified Personal Communicator client and IM and Presence user interface. If a Cisco Unified Personal Communicator user logs into IM and Presence, and LDAP authentication is enabled on Cisco Unified Communications Manager, IM and Presence goes directly to the LDAP directory for Cisco Unified Personal Communicator user authentication. Once Cisco Unified Personal Communicator is authenticated, IM and Presence forwards this information to Cisco Unified Personal Communicator to continue the user login.

Cisco Unified Personal Communicator and third party XMPP clients use the LDAP directory to allow users to search and add contacts.

XMPP interface

An XMPP connection handles the presence information exchange and instant messaging operations for XMPP-based clients. The IM and Presence Service supports temporary (ad-hoc) and persistent chat rooms for XMPP-based clients. An IM Gateway supports the IM interoperability between SIP-based and XMPP-based clients in a IM and Presence deployment.
