Cisco Unified Outbound Option Design Considerations
Managing Failover
Cisco Interaction Manager supports clustered deployments. This ensures high availability and
performance via transparent replication, load balancing, and failover. The following key methods are
available for handling failure conditions within a Cisco Interaction Manager and Unified CCE integrated
deployment:
performance via transparent replication, load balancing, and failover. The following key methods are
available for handling failure conditions within a Cisco Interaction Manager and Unified CCE integrated
deployment:
•
Implementing multiple Web/App servers. If the primary server goes down, the load balancer can
help handle the failure through routing requests to alternate Web/App servers. The load balancer
detects application server failure and redirects requests to another application server, after which a
new user session will be created and users will have to login in again to the Cisco Interaction
Manager.

Allowing servers to be dynamically added or removed from the online cluster to accommodate
external changes in demand or internal changes in infrastructure.

•
Allowing Cisco Interaction Manager services to fail-over with duplexed Unified CCE components
(for example, MR PIM and Agent PIM of the MR PG and Agent PG, respectively) to eliminate
downtime of the application in failure circumstances.

The single points of failure in Cisco Interaction Manager include the following.

Cisco Unified Outbound Option Design Considerations
The Cisco Unified Outbound Option provides the ability for Unified CCE to place calls on behalf of
agents to customers based upon a predefined campaign. The major components of the Unified Outbound
Option are (see
agents to customers based upon a predefined campaign. The major components of the Unified Outbound
Option are (see
):
•
Outbound Option Campaign Manager — A software module that manages the dialing lists and rules
associated with the calls to be placed. This software is loaded on the Logger Side A platform and is
not redundant; it can be loaded and active on only Logger A of the duplex pair of Loggers in the
Unified CCE system.

not redundant; it can be loaded and active on only Logger A of the duplex pair of Loggers in the
Unified CCE system.
•
Outbound Option Dialer — A software module that performs the dialing tasks on behalf of the
Campaign Manager. In Unified CCE, the Outbound Option Dialer emulates a set of IP phones for
Unified CM to make the outbound calls, and it detects the called party and manages the interaction
tasks with the CTI OS server to transfer the call to an agent. It also interfaces with the Media
Routing Peripheral Gateway, and each Dialer has its own peripheral interface manager (PIM) on the
Media Routing Peripheral Gateway.

requests from "non-inbound voice" systems such as the Unified Outbound Option or the
Multi-Channel products. In the Unified Outbound Option solution, each Dialer communicates with
its own peripheral interface manager (PIM) on the Media Routing Peripheral Gateway.
