Note Viewing the Port Certificate Port certificates for voice messaging ports are used only by SCCP integrations with Cisco Unified Communications Manager 6.x and later and are required for authentication of the Unity Connection voice messaging ports. You can view the port certificate that helps in troubleshooting authentication and encryption problems. Procedure Step 1 In Cisco Unity Connection Administration, expand Telephony Integrations and select Port. Step 2 On the Search Ports page, select the display name of the voice messaging port for which you want to see the device certificate. Step 3 On the Port Basics page, select View Certificate. Step 4 In the View Port Certificate window, the information from the port device certificate is displayed. Port Group Port Groups are assigned voice messaging ports that define Unity Connection integration configuration settings. Most of the phone system integrations need only one port group. However, you may need multiple port groups in the following scenarios: • For integration with phone systems through PIMG/TIMG units, each PIMG/TIMG unit is connected to one port group with the applicable voice messaging ports. For example, a system that uses five PIMG units requires five port groups, one port group for each PIMG unit. • For integrations with other phone systems, an additional port group with its own voice messaging ports may be used for testing a new configuration or for troubleshooting.
