Addressing Mode Setup for Cisco Unity Connection

B.

Sure, I'd be happy to explain the answer to this question in detail.

In SIP integrations with Cisco Unified Communications Manager, when Cisco Unity Connection is configured to listen for incoming IPv4 and IPv6 traffic, the addressing mode should be set up in the Cisco Unity Connection. The correct answer to this question is option D: Set up IPv4 and IPv6 in Cisco Unified CM.

To understand why option D is the correct answer, it's helpful to have a basic understanding of IPv4 and IPv6. IPv4 is a protocol used for internet communication that uses 32-bit addresses, while IPv6 uses 128-bit addresses. The use of IPv6 is becoming increasingly important as the number of devices connected to the internet grows, and IPv4 addresses become more scarce.

When it comes to Cisco Unified Communications Manager and Cisco Unity Connection, it's important to ensure that both IPv4 and IPv6 addresses are configured correctly to allow for incoming traffic from both types of devices. Cisco Unified Communications Manager uses IP addressing to communicate with other devices on the network, including Cisco Unity Connection.

So, why is option D the correct answer? This is because setting up IPv4 and IPv6 in Cisco Unified CM ensures that the IP addressing is configured correctly and that both types of devices can communicate with each other. If IPv4 and IPv6 addressing is not properly set up in Cisco Unified CM, this can lead to communication issues between devices and potentially even result in dropped calls or other disruptions in service.

In summary, when configuring SIP integrations with Cisco Unified Communications Manager and Cisco Unity Connection, it's important to ensure that both IPv4 and IPv6 addressing is set up correctly to allow for incoming traffic from both types of devices. The correct answer to this question is option D: Set up IPv4 and IPv6 in Cisco Unified CM.
