4200 User Manual Edgewater Networks, Inc.
Version 3.0 73
J. Enter the TFTP Server Address. This address is used to identify the TFTP
server that contains the images used by IP phones at boot up. The 4200
performs a TFTP server relay function.
PLEASE note: It is not necessary to program in an FTP server address if your IP
phones use the FTP protocol instead of TFTP to retrieve their images. A relay
function is not needed for FTP as the 4200 will forward FTP traffic to the destination
server as programmed in your IP phone.
K. Press Submit.
Configure VoIP Subnet Routing
It is not necessary to configure VoIP subnet routing if all of your voice devices are
installed on the same IP subnet as the 4200. In some installations the voice devices
are located in different subnets than the 4200 and connected via intermediate
routers. In these instances it is necessary to configure a return path in the 4200 by
specifying the intermediate router who knows how to reach the voice devices. This
router must be reachable by the 4200.
