Chapter 16 Using the Cisco Unified Communication Wizard

Configuring the UC-IME by using the Unified Communication Wizard

For the TLS handshake, the two entities, namely the local entity and a remote entity, could validate the peer certificate via a certificate chain to trusted third-party certificate authorities. The local entity and the remote entity enroll with the CAs. The ASA as the TLS proxy must be trusted by both the local and remote entities. The security appliance is always associated with one of the enterprises. Within that enterprise, the entity and the security appliance authenticate each other by using a self-signed certificate.

To establish a trusted relationship between the security appliance and the remote entity, the security appliance can enroll with the CA on behalf of the Cisco Unified Presence server for the local entity. In the enrollment request, the local entity identity (domain name) is used.

To establish the trust relationship, the security appliance enrolls with the third party CA by using the Cisco Unified Presence server FQDN as if the security appliance is the Cisco Unified Presence server.

Note If the ASA already has a signed identity certificate, you can skip Step 1 in this procedure and proceed directly to Step 2.

Step 1 In the ASA’s Identity Certificate area, click Generate CSR. The CSR parameters dialog box appears.

For information about specifying additional parameters for the certificate signing request (CSR), see Generating a Certificate Signing Request (CSR) for a Unified Communications Proxy, page 16-24.

Information dialog boxes appear indicating that the wizard is delivering the settings to the ASA and retrieving the certificate key pair information. The Identity Certificate Request dialog box appears.

For information about saving the CSR that was generated and submitting it to a CA, see Saving the Identity Certificate Request, page 16-25.

Step 2 Click Install ASA’s Identity Certificate. See Installing the ASA Identity Certificate on the Presence Federation and Cisco Intercompany Media Engine Servers, page 16-26.

Step 3 Click Remote Server’s CA’s Certificate. The Install Certificate dialog box appears. Install the certificate. See Installing a Certificate, page 16-23.

Note You must install a root CA certificate for each remote entity that communicates with the ASA because different organizations might be using different CAs.

Step 4 Click Next.

The wizard completes by displaying a summary of the configuration created for the Presence Federation proxy.
