/mcp• Dial plan - The default dial plan in CAR specifies the North American numbering plan (NANP). Ensure that the dial plan is properly configured, so call classifications are correct in the reports. If you have modified the default NANP that Cisco Unified CM Administration provides, or if you are outside the NANP, be sure to configure the dial plan according to your Unified Communications Manager dial plan. • Gateways - To utilize the gateway reports, you need to configure gateways in CAR. You should do this after installation of any existing gateways in your Cisco IP telephony system and when you add gateways to the system. If the system deletes any gateways, CAR gets the latest list of gateways, and any configuration that is specified in CAR for the deleted gateways gets deleted. CAR uses the area code information to determine whether calls are local or long distance. You must provide the Number of Ports information for each gateway to enable CAR to generate the Utilization reports. • System preferences - You can set CAR system preferences for the Company Name parameter. Log On to CAR Only CAR administrators and normal end users can log on to the CAR web interface. Users do not need to be a member of a standard CAR administrator group to be a CAR administrator. Any user who has the role “Standard Admin Rep Tool Admin” associated with the user ID can access CAR as a CAR administrator. The user ID role association gets done by adding the user to a user group that has the role that is associated with it. “Standard CAR Admin Group” and “Standard CCM Super Users” comprise two groups that have the role “Standard Admin Rep Tool Admin” associated with them. The default application user that gets created at installation, who is a member of the “Standard CCM Super Users” group, can log in to CAR as a CAR administrator but only as an application user. This user cannot access the Individual Bills report. CAR supports custom CAR Admin groups. Any custom group that has the role “Standard CAR Admin Group” associated with it can add users who are considered to be CAR administrators when logging into the CAR web interface. End users who are not CAR administrators can log in to CAR only if they have the role “Standard CCM End Users” associated with them. You can do this user ID - role association by adding the end user to the “Standard CCM End Users” group or any other group that has the specified role associated. Any end user without the “Standard CCM End Users” group association cannot log in to the CAR web interface. Any user without the “Standard CCM End Users” or “Standard Admin Rep Tool Admin” role cannot log in to CAR. An attempt by this user to log in to CAR generates a 403 error, and the user gets redirected to the login window with no error message. CAR Web Service traces will log the username of the user who tried to access the application. CAR facilitates users to change their password by using a Change Password window if the user password has expired. When users with an expired password try to log into CAR, they receive IMS_Error_Code 5, 6, or 8. CAR uses the ChangePasswordFilter of ccmadmin to redirect the user to change-password.jsp when any of the preceding error codes are received. The database throttle limits the concurrent users to 100; because of this limit, IMS also supports only 100 users with a login rate of approximately 112 ms. Note If an error occurs while you are resetting the user password, the following message displays on the Change-Password window: “System error while changing password for user. Please contact system administrator.” Call Reporting and Billing Administration Guide for Cisco Unified Communications Manager, Release 15 and SUs 27 CDR Analysis and Reporting Log On to CAR
