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 messages 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 transmitted 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.
