Technical Overview of Cisco CUC

Not sure Cisco Unity Connection is right for you and your organization? The technical overview describes the basics: how to use, where it fits in the architecture, and some requirements.

Cisco Unity Connection offers a collection of REST-based APIs for building web-based or desktop applications for all types of businesses.

Link through to the individual WIKIs to explore the following APIs:

Cisco Unity Connection Provisioning Interface (CUPI) API
CUPI API (for End Users)
Cisco Unity Connection Messaging Interface (CUMI) API
Cisco Unity Connection Telephony Interface (CUTI) API
Cisco Unity Connection Imaging Interface (CUII) API
Cisco Unity Connection Notification Interface (CUNI) API


As of Unity Connection version 10.5, all Unity Connection REST-based APIs support Cisco Single Sign On (SSO) authentication. When SSO is enabled on Unity Connection, all Unity Connection APIs become SSO-enabled.

What is SSO (Single Sign-On)?


Single Sign On (SSO) simplifies the login process for Users and Administrators in Cisco Unified Communications Products (Unified CM and Unity Connection releases 10.5).

SSO offers an easier, more consistent way for users and administrators to authenticate access to secured resources.

Instead of each product requiring a separate user name and password login, a single returned credential allows access to all enabled product interfaces.

Think of SSO as supplying the "skeleton key" to every enabled, authorized service and interface in your environment.
