## Administering Communication Manager for System Wide
Use

This section refers to Communication Manager administration on the Switch Administration Terminal (SAT) or via Avaya Site Administration. The system wide CM form and the particular page that needs to be administered for each feature are provided. These features are recommended because they optimize the telephone user interface. CM 3.0 or greater is required.

Communication Manager Feature Administration
Feature | Administration
--- | ---
On- Hook Dialing | Set up CM so that the phone supports on-hook dialing. Use the System Parameters Features form page 10. Use the command Change system-parameters features to view the form and make the change.
Auto Hold | Set up CM to enable Auto Hold, so that the phone automatically places an active call on hold when the user answers or resumes a call on another call appearance. Use the System Parameters Features form, page 6.
Coverage Path | Administer a coverage path for both phone demonstration and normal operations. Use the Coverage Path form and give it a number, for example, Coverage path 1. If Voice Mail is available, this is also where you administer the hunt group or VDN, depending on the type of VM system being used.
Enhanced Conference Features | Enable enhanced conference display to support the user experience for conferences. Block Enhanced Conference Display on the Class of Restriction (COR) form must be set to No. Use the command Change COR, followed by a number, to view the form and make the change. a sample of the Class of Restriction form.
EC500 | If EC500 licenses have been acquired, enable EC500 on the Off-PBX Telephones Station Mapping form. This feature requires trunking to work properly. Use the following command to make the change:
    Change Off-pbx Telephone Mapping
Wideband Audio | To enable Wideband Audio, use the Change IP codec: command on CM. Ensure that G.722-64K is first on the list of codecs. Note that wide band audio works only for direct-IP calls between two 96xx endpoints, both registered to the same server. Calls between two 96xx phones connected by an IP trunk do not currently support wide band audio. Calls involving three or more parties, even if they are all 96xx phones, will not use wide band. Calls between two 96xx phones where audio is terminated at a port network/gateway (PN/GW) media resource will not use wide band. Ensure that G.722 is added to all codec-sets that can possibly be used between all regions on the IP-Network Regions form where 96xx phones exist.
