The phone ships with three ring tones that are
implemented in hardware: Sunshine, Chirp, Chirp1.
Cisco Unified Communications Manager also provides a default set of additional phone ring sounds that are implemented in software as pulse code modulation (PCM) files. The PCM files, along with an XML file (named Ringlist-wb.xml) that describes the ring list options that are available at your site, exist in the TFTP directory on each Cisco Unified Communications Manager server.
All file names are case sensitive. If you use Ringlist-wb.xml for the file name, the phone will not apply your changes.
You can customize a phone's background image or wallpaper in two ways:
Using the List file
Using a Common Phone Profile
If you want the user to be able to select your image from various wallpapers available on the phone, then modify the List file. But if you want to push the image to the phone, then create or modify an existing Common Phone Profile.
Your images must be in PNG format and the dimensions of the full sized image must be within 800 pixels by 480 pixels. Thumbnail images are 139 pixels (width) by 109 pixels (height).
Upload the images and List file to your TFTP server. The directory is Desktops/800x400. Restart the server after the upload is done.
If you modify your Common Phone Profile, then add the new image to the Background Image field in the format mylogo.png. If you don't want the user selecting their own wallpaper, then uncheck Enable End User Access to Phone Background Image Setting. Save and apply the phone profile. Restart the phones so your changes take effect.
For more information on selecting the wallpaper on the phone, see the "Settings" chapter in the Cisco IP Phone 8800 Series User Guide.
Set Up Wideband
default, the G.722 codec is enabled for the Cisco IP Phone.
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
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 far endpoint 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 distracting. Other users may prefer the additional
sensitivity of G.722.
G.722 and iSAC 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.
wideband support for all devices:
Cisco Unified Communications Manager Administration, choose
System > Enterprise
Advertise G.722 and iSAC Codec field
default value of this enterprise parameter is
True, which means that all Cisco IP Phone Models
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.
wideband support for a specific device:
Unified Communications Manager Administration, choose
Device > Phone.
Advertise G.722 and iSAC Codec parameter in the Product Specific Configuration
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
Set Up Idle
specify an idle display (text only; text file size should not exceed 1M bytes)
that appears on the phone screen. The idle display is an XML service that the
phone invokes when the phone is idle (not in use) for a designated period and
no feature menu is open.
