Wideband Codec Setup; Phone Only Mode - Cisco DX650 Administration Manual

Wideband Codec Setup

Wideband Codec Setup
By default, the G.722 codec is enabled for the Cisco Desktop Collaboration Experience. If Cisco Unified
Communications Manager is configured to use G.722 and if the far endpoint supports G.722, the call connects
using the G.722 codec in place of G.711.
This situation occurs regardless of whether the user has enabled a wideband headset or wideband handset,
but if either the headset or handset is enabled, the user may notice greater audio sensitivity during the call.
Greater sensitivity means improved audio clarity but also means that the party at the far end can hear more
background noise: noise such as rustling papers or nearby conversations. Even without a wideband headset
or handset, some users may prefer the additional sensitivity of G.722. Other users may find the additional
sensitivity of G.722 distracting.
The Advertise G.722 Codec service parameter affects whether wideband support exists for all devices that
register with this Cisco Unified Communications Manager server or for a specific phone, depending on the
Cisco Unified Communications Manager Administration window where the parameter is configured:
• Advertise G.722 Codec field: From Cisco Unified Communications Manager Administration, choose
• A specific phone advertises the G.722 codec: From Cisco Unified Communications Manager

Phone Only Mode

Enable Phone Only Mode to limit the user access on the phone to the home screen, Phone application, Contacts
application, and Settings application. The user cannot add shortcuts or widgets to the home screen in Phone
Only Mode. Any contacts saved to the Contacts application in Phone Only Mode will be stored locally, and
will not sync to any server. USB storage devices and SD cards are not supported in Phone Only Mode. Any
previously configured account data is hidden from the user when the phone enters Phone Only Mode.
The phone reboots when you switch from Standard Profile to Phone Only Mode, or from Phone Only Mode
to Standard Profile.
Cisco recommends that you disable Android Debug Bridge (ADB) for phones in Phone Only Mode.
Because the Email application is disabled in Phone Only Mode, the user will be unable to use the Problem
Report Tool to email logs to the administrator. The user must collect the logs from the serviceablity web page.

System > Enterprise Parameters. The default value of this enterprise parameter is True, which means
that all Cisco Desktop Collaboration Experience DX600 series devices that register to this Cisco Unified
Communications Manager advertise G.722 to Cisco Unified Communications Manager. If each endpoint
in the attempted call supports G.722 in the capabilities set, Cisco Unified Communications Manager
chooses that codec for the call whenever possible.
Administration, choose Device > Phone. The default value of this product-specific parameter is to use
the value that the enterprise parameter specifies. If you want to override this on a per-phone basis, choose
Enabled or Disabled in the Advertise G.722 Codec parameter in the Product Specific Configuration
area of the Phone Configuration window.
