Cisco Cisco E-Mail Manager Unity Integration Option Installation Guide

Currently, the Cisco Unified Contact Center Security Wizard’s Windows Firewall 
tool is not programmed to automatically create exceptions for RSM. RSM will not 
work properly if this tool is used to enable Windows Firewall on the RSM server.

RSM fully supports Cisco Security Agent (CSA) for ICM. It is highly 
recommended that CSA for ICM be installed on the RSM server. Refer to the 
“Base System Provisioning” topic in Chapter 3, Pre-Installation Tasks. 

Currently, network level IP security (IPsec) encryption is the only supported 
method for securing high-level protocols between RSM and other Unified CCE 
components.

For recommended and supported IP sec tunnel configurations, refer to the 
“Support for IPSec (IP Security) in Transport Mode” topic in Chapter 2 of the 
Security Best Practices Guide for ICM and IPCC Enterprise & Hosted Editions 
document (cf. “Windows Security Hardening” topic, above). 

ICM allows IPsec policies to be set up manually (e.g., via the Microsoft 2003 
Server security tools), or via the Cisco Network Isolation Utility. Note that RSM 
supports only manually configured peer-to-peer IPsec tunnels and does not 
support the Cisco Network Isolation Utility. 

IPsec for secure CTI OS and JTAPI communication is described below.

To encrypt CTI OS communications between the RSM server and a PG CTI OS 
server, an IPsec tunnel may be configured. If the environment has multiple PGs 
that the RSM server is configured to use, this approach may be used with each PG 
or only certain ones (e.g., only PGs over a certain insecure network connection).
