In-Depth Information
CUE not only functions as a voicemail solution, but also includes auto-attendant (AA) capability. Integration between CUE and CME
is provided using a SIP interface, while integration with CUCM is offered through JTAPI.
CUE is supplied as either a Network Module (NM-CUE) or as an Advanced Integration Module (AIM-CUE).
The following two sections describe CUE deployment models and integration with CME.
CuE Deployment Models
CUE offers three standard deployment models:
■
Standalone office:
A single-site deployment. CUE typically is deployed with CME, although it is possible to deploy it with
Cisco CUCM.
■
Multisite network with CME (distributed call processing/voicemail):
A deployment in which there are multiple sites and
CUE is deployed at each site in conjunction with CME.
■
Multisite network with CUCM (centralized call processing/distributed voicemail):
In this type of deployment, Cisco
CUCM is deployed at a central site to provide call processing for phones at all sites, and SRST is provided at remote sites.
Voicemail is deployed in a distributed architecture, with Cisco Unity at the central site and CUE at the remote sites.
Figure 5-3
illustrates these three deployment options.
