Digital Picture Frame
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.

Note
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.
