The network bandwidth necessary to send the encoded voice is typically 5-10%
(confirm number) higher than the encoded bit rate due to packetization overhead.
For example, a G.722.1C call at 48kbps consumes 5x kbps of network bandwidth.
Configuration changes can performed centrally at the boot server:
Specify codec priority, preferred payload sizes, and jitter buffer tuning
parameters.

A slide show of multiple personal images stored on a USB flash drive can be
displayed on the Polycom VVX 1500 phone during the idle mode. The
supported formats include JPEG, BMP, and PNG. The maximum image size is
9999x9999. A maximum of 1000 images can be displayed and these must be
stored in a directory of the USB flash drive that you create.
Although 9999x9999 images are supported, progressive/multiscan JPEG images
are not supported at this time no matter their resolution.
Configuration changes can be performed centrally at the boot server:
Turn this feature on or off and configure how it appears.
