Media Termination Point Configuration


A Media Termination Point software device allows Cisco Unified Communications Manager to relay calls that are routed through SIP or H.323 endpoints or gateways. You can allocate a media termination point device because of DTMF or RSVP requirements. When a media termination point is allocated for RSVP, you can insert it between any type of endpoint device, including SIP or H.323 devices.

Media termination point, a Cisco software application, installs on a server during the software installation process. You must activate and start the Cisco IP Voice Media Streaming App service on the server on which you configure the media termination point device. For information on activating and starting services, refer to the Cisco Unified Serviceability Administration Guide.

Each media termination point device that is defined in the database registers with the Media Resource Manager (MRM). The MRM keeps track of the total available media termination point devices in the system and of which devices have available resources.

During resource reservation, the MRM determines the number of resources and identifies the media resource type (in this case, the media termination point) and the location of the registered media termination point device. The MRM updates its share resource table with the registration information and propagates the registered information to the other Cisco Unified Communications Managers within the cluster.

The media termination point and transcoder can register with the same Cisco Unified Communications Manager. See the "Transcoder Configuration" section on page 69-1 for more information.

Each media termination point receives a list of Cisco Unified Communications Managers, in priority order, to which it should attempt to register. Each media termination point can register with only one Cisco Unified Communications Manager at a time.


Note Depending on the capabilities of the SIP endpoint, Cisco Unified Communications Manager may require an RFC 2833 DTMF-compliant media termination point device to make SIP calls. For RSVP calls, the Media Resource Group List (MRGL) that is associated with the endpoint device needs to include the media termination point devices that support RSVP.

Finding a Media Termination Point

Because you might have several media termination points in your network, Cisco Unified Communications Manager lets you locate specific media termination points on the basis of specific criteria. Use the following procedure to locate media termination points.


Note During your work in a browser session, Cisco Unified Communications Manager Administration retains your media termination point search preferences. If you navigate to other menu items and return to this menu item, Cisco Unified Communications Manager Administration retains your media termination point search preferences until you modify your search or close the browser.


Procedure


Step 1 Choose Media Resources > Media Termination Point.

The Find and List Media Termination Points window displays. Records from an active (prior) query may also display in the window.

Step 2 To find all records in the database, ensure the dialog box is empty; go to Step 3.

To filter or search records

From the first drop-down list box, select a search parameter.

From the second drop-down list box, select a search pattern.

Specify the appropriate search text, if applicable.


Note To add additional search criteria, click the + button. When you add criteria, the system searches for a record that matches all criteria that you specify. To remove criteria, click the - button to remove the last added criterion or click the Clear Filter button to remove all added search criteria.


Step 3 Click Find.

All matching records display. You can change the number of items that display on each page by choosing a different value from the Rows per Page drop-down list box.


Note You can delete multiple records from the database by checking the check boxes next to the appropriate record and clicking Delete Selected. You can delete all configurable records for this selection by clicking Select All and then clicking Delete Selected.


Step 4 From the list of records that display, click the link for the record that you want to view.


Note To reverse the sort order, click the up or down arrow, if available, in the list header.


The window displays the item that you choose.

Configuring a Media Termination Point

This section describes how to add, copy, or update a Media Termination Point.


Note To perform this procedure, you must activate the Cisco IP Voice Media Streaming App service by using Cisco Unified Serviceability. For information about activating services, refer to the Cisco Unified Serviceability Administration Guide.


Before You Begin

Make sure that the following prerequisites are met before you proceed with the steps:

Ensure servers are configured.

Ensure device pools are configured.


Note You can have only one Media Termination Point device for each Cisco Unified Communications Manager server. When a Cisco Unified Communications Manager Server is added, a media termination point device automatically gets created for the server but is not available for use until the Cisco IP Voice Media Streaming App service gets activated.


Procedure


Step 1 Perform one of the following tasks:

To add a Media Termination Point, choose Media Resources > Media Termination Point. The Find and List Media Termination Point window displays. Click Add New.

To copy a Media Termination Point, choose Media Resources > Media Termination Point. The Find and List Media Termination Point window displays. Click the Copy icon next to the media termination point that you want to copy.

To update a Media Termination Point, locate the media termination point by using the procedure in the "Finding a Media Termination Point" section.

Step 2 Enter the appropriate settings as described in Table 65-1.

Step 3 Click Save.

Deleting a Media Termination Point

This section describes how to delete a Media Termination Point.

Before You Begin

Before deleting a media termination point that is currently in use and is the last device in the Media Resource Group, you should perform either or both of the following tasks:

Assign a different media termination point to the media resource groups that are using the media termination point that you want to delete. See the "Finding a Media Resource Group" section on page 70-1 section.

Delete the media resource groups that are using the media termination point that you want to delete. See the "Deleting a Media Resource Group" section on page 70-5.

Procedure


Step 1 Locate the media termination point by using the procedure in the "Finding a Media Termination Point" section.

Step 2 Click the media termination point that you want to delete.

Step 3 Click Delete Selected.

A message displays the following warning:

You are about to permanently delete this Media Termination Point. This action cannot be undone.

Continue?

Step 4 To delete the media termination point, click OK.

If this is the last device in the Media Resource Group, the Media Resource Group will remain as an empty group.

Step 5 Click OK.
