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.

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.
