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.

 

 

 

 

 

 

 

 

Configuration changes can performed centrally at the boot server:

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

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:
