TFTP server IP address and TFTP server filename: Enter the
IP address and the complete file name for the operating software
of the VoIP system telephone (see table on page 132). For the

system.
Registration IP address and Registration port: This is where
you usually enter the IP address of the Forum 523/524 and the
port number 8100.
Default gateway: Click on the Add parameter command to
have this optional entry field displayed. Then enter the IP address
of the router (“Default Gateway”). Click on the Delete button to
remove the optional parameter.
SYSLOGD: For monitoring purposes, VoIP system telephone mes-
sages can be sent to a Syslog server. Activate the yes option and
configure the SYSLOGD IP address and SYSLOGD port settings
to activate this function.
VLAN (Expert option - do not change the “no” setting in standard
cases): To improve transmission security or to enforce security
guidelines, PC data transmission and VoIP data transmission can
be separated using this method. Activate the yes option and enter
the desired IP Phone VLAN ID for the VoIP data transmission.
Enter a value ranging from 1-4094. Data will always be transmit-
ted without a VLAN tag at the VoIP system telephone’s PC access.
If you activate the yes option for PC traffic tagged on LAN
interface, PC data will be labelled with the PC VLAN ID at the
LAN access. Please note that to change the VLAN settings, the
VoIP system telephone has to be restarted.
