Multiple deployments for partitioning mobile and remote
access to Unified Communications services
access to Unified Communications services
This release introduces the concept of "deployments" to the Expressway.
A deployment is an abstract boundary used to enclose a domain and one or more Unified Communications
service providers, such as Unified CM, Cisco Unity Connection, and IM and Presence Service nodes.
service providers, such as Unified CM, Cisco Unity Connection, and IM and Presence Service nodes.
The purpose of multiple deployments is to partition the Unified Communications services available to mobile
and remote access (MRA) users. This enables different subsets of MRA users to access different sets of
services over the same Expressway pair. We recommend that you do not exceed 10 deployments.
and remote access (MRA) users. This enables different subsets of MRA users to access different sets of
services over the same Expressway pair. We recommend that you do not exceed 10 deployments.
For example, consider an implementation of two sets of Unified Communications infrastructure to provide a
live MRA environment and a staging environment, respectively. This implementation might also require an
isolated environment for sensitive communications.

Secure connection checker
This new utility enables you to test whether or not a secure connection can be made from the Expressway. It
checks the validity of certificates presented by the transacting parties, looking for errors that would prevent
the secure connection.
