Cisco Cisco Unified IP Interactive Voice Response (IVR) 8.0(1) Administrator's Guide

Database. The Database subsystem enables CRS applications to 
communicate with enterprise database servers.

eMail. The eMail subsystem enables CRS applications to create and send 
e-mail.

For detailed instructions on provisioning these four subsystems, see 

After you provision the CRS subsystems, you need to configure CRS applications 
to interact with contacts and perform a wide variety of functions.

To continue the CRS system configuration process, connect to the Cisco CRS 
Administration web interface and manage the following tasks:

There are several types of applications you can configure for Cisco CRS:

Script applications perform such functions as receiving calls, playing back 
prompts, receiving caller input, transferring calls, and queueing calls.

The Busy application simulates a busy signal. 

The Ring-No-Answer application simulates a ring tone.

In addition, if your CRS system is to be configured to interface with Unified IP 
IVR for Unified ICME (not with Unified CCX by way of the IPCC Gateway), two 
extra applications are available: Unified ICME post-routing applications and 
Unified ICME translation-routing applications. For more information on these 
applications, see 

,

After adding a Cisco CRS application, you need to define a trigger so that this 
application can respond to telephone calls and/or HTTP requests. Triggers are 
specified signals that invoke application scripts in response to incoming contacts.
