SIP Route Pattern Caller ID Configuration

D.

In Cisco Unified Communications Manager (CUCM), the Calling Party Transformation Mask field is used to modify the caller ID information for outbound calls made through a specific SIP Route Pattern.

The Calling Party Transformation Mask field is located in the SIP Route Pattern configuration page. This field allows you to change the caller ID information by modifying the Calling Party Number (i.e., the number of the person making the call).

For example, if you have an outbound SIP trunk to a specific service provider, and that provider requires a specific format for caller ID information, you can use the Calling Party Transformation Mask field to modify the caller ID information to meet the provider's requirements.

To configure the Calling Party Transformation Mask for a SIP Route Pattern, follow these steps:

1. Open the CUCM administration interface and navigate to Call Routing > SIP Route Pattern.
2. Locate the SIP Route Pattern for which you want to modify the caller ID information, and click on it to open the configuration page.
3. Scroll down to the Calling Party Transformation section.
4. In the Calling Party Transformation Mask field, enter the desired caller ID information. This can be a specific phone number, or it can be a text string that will be displayed as the caller ID information.
5. Click Save to save the configuration changes.

Once you have configured the Calling Party Transformation Mask for a SIP Route Pattern, all outbound calls made through that pattern will have their caller ID information modified according to the configuration you have specified.
