High Availability and Fault Tolerance in IPCC Gateway Deployments

This section describes how IPCC Gateway deployments accommodate failover.

About IPCC Enterprise Solutions and Fault Tolerance

For an IPCC Enterprise solution in an IPCC Gateway deployment, fault tolerance is achieved
as it is with other ICM PGs; there is a Side A and Side B PG which can connect to either side
(A or B) of a System PG on a child system.

For more information about fault tolerance, see the IPCC Installation and Configuration Guide
for Cisco IPCC Enterprise Edition.

About IPCC Express Solutions and High Availability

An IPCC Express solution in an IPCC Gateway deployment does not support the Side A/Side
B model of fault tolerance. Instead, it supports a high availability model.

In the high availability model, the IPCC Express cluster looks like one ACD to the ICM
Enterprise parent, and a Side A PG is installed on both nodes of IPCC Express.

For more information, see

About IPCC Gateway Deployments

This section discusses the supported IPCC Gateway deployment models.

IPCC Gateway using IPCC Enterprise Gateway PG

The following topics explain two ways that you can deploy the IPCC Enterprise Gateway PG:

Multiple ICM (parents) with Single IPCC Enterprise (child)

The following figure shows a deployment where two customers (Customer 1 and Customer 2)
each running their own ICM Enterprise parent, outsourcing calls to provider site running IPCC
Enterprise with System PGs. The provider site has an IPCC Enterprise installation with two
IPCC System PGs that connect to their respective IPCC Enterprise Gateway PG for each ICM
