Configuring Cisco CUCM 8.6 with OVA Template Download

When it comes to configuring a Cisco Unified Communications Manager (CUCM) 8.6 system, there are several key settings that need to be in place for multicast routing to function properly. In this article, we will walk through the steps needed to configure CUCM 8.6 using an OVA template download.

Multicast Routing Configuration

The first step is to enable multicast routing throughout the entire network. This involves adding the 'Pim sparse-dense-mode' command in the gateway configuration, as shown below.

MOH Server Configuration

Next, we need to configure the MOH server to use multicasting. This involves enabling Multicasting and defining how we will configure the multicast IP on the gateway as well as the port number.

Device Pool Configuration

In the Device Pool configuration, we can optionally configure an MRGL (Media Resource Group List) if it has not been taken care of at the Phone Configuration page. This allows us to place our MRG inside the selected resource groups in order to access the MOH server and file correctly.

Phone Configuration

In the Phone Configuration page, we need to configure the locations that will allow us to access an MOH server/file. If the MRGL has been taken care of at the Device Pool level, it is not necessary to configure it here.

MRG and Multicast Configuration

To complete the configuration, we need to enable the Multicast checkbox in the MRG setup and reset these as needed. It is important to note that customers may not realize that these settings must show up as 'Registered with ...' in order to work properly.

MOH Server Verification

Once all the settings have been configured, we can verify how many MOH servers are available and where exactly they are registered to. We can also make configuration changes for multicasting and verify what codecs are supported with the stream that has been installed.

In conclusion, configuring Cisco CUCM 8.6 with an OVA template download requires careful attention to several key settings. By following these steps, you can ensure that your system is properly configured for multicast routing and MOH server/file access. Remember to verify the registration of all settings and make any necessary changes to ensure proper functionality.
