Explanation

To secure the connection between Cisco Unified Communications Manager (UCM) and Cisco Unity Connection using TLS, a Certificate Signing Request (CSR) must be generated on each server. The CSR is then submitted to a Certificate Authority (CA) to obtain a signed certificate. Once the certificate is received, it is installed on the respective server. 1. Generate the CSR: On both Cisco UCM and Cisco Unity Connection servers, generate a CSR from their administrative interfaces. The CSR contains essential details, such as the server's hostname and public key. 2. Submit the CSR to the CA: Provide the CSR to a trusted Certificate Authority (internal or external). The CA verifies the identity of the server and signs the certificate. 3. Download and Install the Signed Certificate: After receiving the signed certificate from the CA, install it on each server. This certificate will be used to establish a secure TLS connection. 4. Install the CA Certificate: Ensure the CA's root certificate is installed in the trust store of both Cisco UCM and Cisco Unity Connection to establish mutual trust. By following the process of generating a CSR and submitting it to a CA, the engineer ensures that the certificates are correctly signed and installed, securing the connection between Cisco UCM and Cisco Unity Connection using TLS.
