Making a video phone call with best possible picture quality
Making a video phone call with best possible
picture quality
The following tips will help ensure that you and the parties you call experience the
best possible picture quality when making video phone calls:
•
For the best picture quality, configure Video Call Bandwidth at 768kbps for
the appropriate Regions and/or Locations. See the Cisco Unified
CallManager Administration Guide for more information on configuring
CallManager for Video Telephony.
•
Make sure the camera focus is adjusted correctly. Press the Selfview button,
then rotate the black ring around the camera lens to adjust the focus.
• Also while in Selfview mode, ensure that you are seeing a good quality
picture that is not overly bright or overly dim. If the image looks too dim or
too bright, try moving the position of the phone and/or rotating the camera up
and down until you get a good picture. If the Selfview image shows shadows
on your face or the image is too dim, consider using a small desk lamp to
brighten the image.
•
Ensure that the Cisco Unified IP Video Phone 7985G is being used in a well
lit space. This is important since low light conditions will affect the video
frame rate of the camera resulting in a poor video quality, especially when the
subject is moving.
•
Avoid direct sunlight on any surface within the camera's view
