Settings for Configuring SIP Route Pattern in Cisco Unified Communications Manager

C.

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

In Cisco Unified Communications Manager (CUCM), a SIP route pattern is a way to route calls to SIP trunks or other SIP-enabled devices based on a specific dialing pattern. To configure a SIP route pattern in CUCM, you need to configure the following settings:

1. Pattern usage: This setting defines how the SIP route pattern is used. You can choose from the following options:

• Standard: This option is used for regular call routing.
• Intercluster: This option is used for calls between different clusters in a multi-cluster environment.
• Intracluster: This option is used for calls within the same cluster.

2. IPv4 pattern: This setting defines the dialing pattern for IPv4 addresses. This can be a specific number, range of numbers, or wildcard characters. For example, if you want to route all calls to a specific SIP trunk that starts with the number "9", you could use the pattern "9XXX".

3. IPv6 pattern (optional): This setting defines the dialing pattern for IPv6 addresses. This is only necessary if you are routing calls to IPv6-enabled devices.

4. SIP trunk/Route list: This setting defines the SIP trunk or route list that the calls should be routed to. A SIP trunk is a connection between CUCM and another SIP-enabled device, such as a VoIP provider or gateway. A route list is a list of SIP trunks that can be used to route calls to a specific destination.

5. Description (optional): This setting allows you to add a description to the SIP route pattern to help identify its purpose or usage.

Based on the above explanation, the correct answer to the question is C. Pattern usage, IPv4 pattern, and SIP trunk/Route list are the minimum settings required to configure a SIP route pattern in CUCM. While the IPv6 pattern and description settings can be useful in certain scenarios, they are not required for basic configuration.
