Transcoder Configuration Settings

The Media Resource Manager (MRM) has responsibility for resource registration and resource reservation of transcoders within a Cisco Unified Communications Manager cluster. Cisco Unified Communications Manager simultaneously supports registration of both the Media Termination Point (MTP) and transcoder and concurrent MTP and transcoder functionality within a single call.

The Cisco Unified Communications Manager invokes a transcoder on behalf of endpoint devices when the two devices are using different codecs and would normally not be able to communicate. When inserted into a call, the transcoder converts the data streams between the two disparate codecs to enable communications between them.

A transcoder control process gets created for each transcoder device that is defined in the database. Each transcoder registers with the MRM when it initializes. The MRM keeps track of the transcoder resources and advertises their availability throughout the cluster.

Table 76-1 describes the transcoder configuration settings. For related procedures, see the "Related Topics" section.

Table 76-1 Transcoder Configuration Settings

Finding a Transcoder

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


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


Procedure


Step 1 Choose Media Resources > Transcoder.

The Find and List Transcoders 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.
