New Information

The following information is new for Cisco Unified IP Conference Station 7937G running firmware release 1.4(4):

Accessibility Feature

Audio Parameter

Early Offer Feature

LLDP-MED and CDP Support

Accessibility Feature

The Cisco Unified IP Conference Station 7937G now supports a Color Blind feature when the user goes on mute. When you mute the Cisco Unified IP Conference Station 7937G, `MUTE-ON' displays on the phone screen until you unmute the phone.

Audio Parameter

Cisco Unified CM Administration supports a new audio parameter that administrators use to set voice quality control. Use the voice quality control parameter when the Cisco Unified IP Conference Station 7937G is used in large conference rooms.

To access the Voice Quality Control parameter, follow these steps:

Procedure


Step 1 Log in to the Cisco Unified Communications Manager Administration application.

Step 2 From the menu bar, choose Device > Phone.

The Find and List Phones window appears.

Step 3 Search for the phone you want to configure.

A list of matching records displays.

Step 4 Select the phone you want to configure.

The Phone Configuration window appears.

Step 5 In the Product Specific Configuration Layout portion of the window, enable or disable the Voice Quality Control parameter.


Early Offer Feature

Cisco Unified CM 8.5(1) or later allows an administrator to enable the Early Offer feature on the trunk without the use of a MTP resource. To support this, the SCCP stack has been enhanced with the `getPort capability,' and three new SCCP messages are added. This allows Cisco Unified CM to open and close audio and video ports on the Cisco Unified IP Conference Station 7937G, which Cisco Unified CM uses to build the SDP offer.
