Chapter 16 Using the Cisco Unified Communication Wizard

Configuring the UC-IME by using the Unified Communication Wizard

To configure the Cisco Intercompany Media Engine Proxy by using ASDM, choose Wizards > Unified Communication Wizard from the menu. The Unified Communication Wizard opens. From the first page, select the Cisco Intercompany Media Engine Proxy option under the Business-to-Business section and click Next.

Note The Cisco Intercompany Media Engine Proxy does not appear as an option in the Unified Communication Wizard unless the license required for this proxy is installed on the ASA.

When using the wizard to create the Cisco Intercompany Media Engine Proxy, ASDM automatically creates the necessary TLS proxies, enables SIP inspection for Cisco Intercompany Media Engine traffic, generates address translation (static PAT) statements for local Cisco Unified Communications Manager servers, and creates ACLs to allow traffic between the local Cisco Unified Communications Manager servers and the remote servers.

The following steps provide the high-level overview for configuring the Cisco Intercompany Media Engine Proxy:

Step 1 Select the topology of the Cisco Intercompany Media Engine Proxy, namely whether the security appliance is an edge firewall with all Internet traffic flowing through it or whether the security appliance is off the path of the main Internet traffic (referred to as an off-path deployment). See Configuring the Topology for the Cisco Intercompany Media Engine Proxy, page 16-17.

Step 2 Specify private network settings such as the Cisco UCM IP addresses and the ticket settings. See Configuring the Private Network Settings for the Cisco Intercompany Media Engine Proxy, page 16-18.

Step 3 Specify the public network settings. See Configuring the Public Network Settings for the Cisco Intercompany Media Engine Proxy, page 16-20.

Step 4 Specify the media termination address settings of the Cisco UMC. See Configuring the Media Termination Address for Unified Communication Proxies, page 16-10.

Step 5 Configure the local-side certificate management, namely the certificates that are exchanged between the local Cisco Unified Communications Manager servers and the security appliance. See Configuring the Local-Side Certificates for the Cisco Intercompany Media Engine Proxy, page 16-21.

Step 6 Configure the remote-side certificate management, namely the certificates that are exchanged between the remote server and the ASA. This certificate is presented to remote servers so that they can authenticate the ASA as a trusted server. See Configuring the Remote-Side Certificates for the Cisco Intercompany Media Engine Proxy, page 16-22.

The wizard completes by displaying a summary of the configuration created for the Cisco Intercompany Media Engine.

Configuring the Topology for the Cisco Intercompany Media Engine Proxy

Step 1 Select the topology of your ICME deployment by clicking one of the following options:

•All Internet traffic flows through the ASA radio button. This option is also referred to as a basic deployment.

•This ASA is off the path of the regular Internet traffic. This option is also referred to as an off-path deployment.
