After configuring the 4300T VoIP ALG the voice devices must be configured
to point to the LAN interface of the 4300T as their signaling gateway and
optionally as their TFTP server (if they use the TFTP protocol to retrieve their
software images). The steps required to setup these devices differ from vendor
to vendor. Using the DHCP server included in the 4300T will significantly
simplify the setup of these devices if they are able to obtain their IP
configuration via DHCP. Please consult the applicable users guide of each
device for detailed instructions.
