The following sections describe how to configure call routing by using the administrative console:

•Configuring Routes

•Configuring Dial Patterns

•Configuring Remote Service Providers

•Viewing Call Detail Records

Configuring Routes

On the Cisco TelePresence Exchange System, a route is a reference to an adjacency on a Cisco Session Border Controller (SBC). Each adjacency on the SBC is assigned a unique tag. The tag value is included in SIP messages between the SBC and Cisco TelePresence Exchange System, which simplifies routing.

For example, the SBC uses an adjacency for each hosted organization. The adjacency is configured with a unique tag. The same tag value is configured in the Cisco TelePresence Exchange System route for that organization. Therefore, the outgoing route on the SBC is found by matching the tag value.

The following sections describe how to configure routes:

•Adding Routes

•Editing Routes

•Deleting Routes

•Route Fields

Viewing Call Detail Records

The Cisco TelePresence Exchange System collects and displays call detail records (CDRs) for calls that are placed on the system. From the administration console, you can view CDR details for the system as well as export a comma separated value (.csv) file of that information. The system saves up to 30 days of CDR information and deletes any records older than 30 days on a daily basis.

When viewing CDRs through the administration console, you can filter the listing by each category heading (such as caller, service provider, organization, Meet-Me conference ID, and start and end time).

The following sections describe how to view, export, and filter CDRs:

•Viewing and Filtering CDRs

•Exporting a CDR File

For instructions on viewing intra-company call detail records, see the "Viewing Intra-Company CDRs" section.

Viewing and Filtering CDRs

Procedure

To view and filter CDRs for the system, do the following procedure:

Step 1 From the navigation pane, choose Call Routing > CDRs.

The CDRs window is displayed showing details on meetings for the past 30 days.

Step 2 (Optional) To filter the information that is displayed on the CDRs window, do one of the following:

•To filter on the call type and CDR source information that is displayed on the CDR window, click the T icon next to the column heading, and check the check boxes next to each item that you want to display on the window.

To display CDRs for all items, check All.

•To filter on any specific heading other than call type and CDR source such as organization (for example ABC Company), click the T icon next to the column heading, and enter the specific item on which you want to filter.

Step 3 To activate the filter, click Filter.

To deactivate a filter, click the T icon next to the appropriate column heading and click Clear.

Note When you click Clear Filters, the system clears all defined filters.

Exporting a CDR File

To capture the information that is displayed on the Call Routing > CDRs window, you can export a CDR file. When you export the CDR file, additional information for each CDR entry is available beyond what is viewable on the CDRs window, for example, the call engine name and IP address, which can be useful for troubleshooting purposes.

Procedure

To export a CDR file from the system, do the following procedure:

Step 1 From the navigation pane, choose Call Routing > CDRs.

The CDRs window is displayed showing details on meetings.

Step 2 To export a file that summarizes CDRs for the last 30 days, click Export CDRs.

A panel appears with options to either view or save the export.csv file.

Viewing Intra-Company CDRs

Intra-company (direct dial) calls are not routed via the Cisco TelePresence Exchange System cluster. As a result, the Cisco TelePresence Exchange System by default is not aware of these calls and does not generate any CDRs for them. Therefore, if you need to view intra-company CDRs, you must configure the Cisco TelePresence Exchange System to periodically pull the CDRs from Cisco Unified Communications Manager and to generate them locally as if the calls had been processed by the Cisco TelePresence Exchange System itself.

Note•The collected CDRs are stored on the Cisco TelePresence Exchange System with all the other CDRs, with the cdrSource set to INTRACOMPANY_DIRECTDIAL.

•CDRs are imported hourly, and the timing for collection is also dependent on the schedule for CDR files being generated in Unified CM. Unless by chance a call comes in at exactly the right time to be included in the Unified CM processing and the Cisco TelePresence Exchange System processing immediately, you may need to wait an hour or two before the CDR appears in the database.

See the following "Configuring Unified CM to Enable Intra-Company CDRs" section for detailed instructions.

Configuring Unified CM to Enable Intra-Company CDRs

To configure Cisco Unified Communications Manager to enable intra-company CDRs and then to provision the Unified CM publisher node in the Cisco TelePresence Exchange System administration console, do the following two procedures in the order presented.

Procedure

Step 1 Log in to the Cisco Unified Communications Manager publisher node as the administrator.

Step 2 From the Navigator menu, select Cisco Unified Serviceability and click Go.

Step 3 Choose Tools > Service Activation.

Step 4 From the Select Server drop-down list, select the publisher node.

Step 5 Verify that under the CDR Services menu, both the Cisco SOAP - CDRonDemand Service and the Cisco CAR Web Service check boxes are checked. If they are not checked, check them and click Save to activate these services.

Step 6 To create a custom API user for the CDR APIs in Unified CM, from the navigation menu, select Unified CM Administration and click Go.

Note The default ccmadministrator user can be used instead of the custom API user. However, for security reasons, Cisco recommends that a separate API user be created for the Cisco TelePresence Exchange System application to pull the CDRs from Unified CM.

Step 7 Choose User Management > Application User and click New to create a new application user.

Step 8 Choose User Management > User Group and click Standard CAR Admin Users.

Step 9 Click Add App Users to Group and select the application user that you created in Step 7.

Step 10 Repeat Step 8 and Step 9 for Standard CCM End Users and Standard CCM Read Only.

Step 11 Continue with the following procedure to provision Unified CM in the Cisco TelePresence Exchange System administration console.

Procedure

Step 1 In the Cisco TelePresence Exchange System administration console, from the navigation pane, choose Media Resources > Unified CM Resources.

Step 2 Enter or edit information on the applicable Unified CM page to indicate the address of the Unified CM and the username and password of the API user that you created in Step 7 of the previous procedure.

Step 3 Click Test Connection to validate the username and password that you entered in Step 2.

When both Unified CM and the Cisco TelePresence Exchange System have been configured correctly to enable intra-company CDRs, the message "Connection has been verified." is displayed.

When there is a mismatch in the credentials, the error message "Connection failed verification. Error accessing API." is displayed. Verify the login credentials and if necessary the Host address of the Unified CM and repeat Step 3 until the "Connection has been verified" message is displayed.
