bandwidth-limited WAN links.

 

 

 

When enabled, it allows the phone to discover like phones on

firmware image, and to automatically assemble transfer

 

 

 

hierarchies on a per-file basis. The individual files making up

 

 

 

the firmware image are retrieved from the TFTP server by

 

 

 

only the root phone in the hierarchy, and are then rapidly

 

 

 

transferred down the transfer hierarchy to the other phones on

 

 

 

the subnet using TCP connections
