Note
GARP Enabled
Indicates whether the phone learns MAC addresses from
Gratuitous Address Resolution Protocol (ARP)
responses. Disabling the phone's ability to accept
Gratuitous ARP will prevent applications that use this
mechanism to monitor and record voice streams from
working. If voice monitoring is not desired, set this
option to No (disabled).
Voice VLAN
Indicates if the phone allows a device attached to the
Enabled
access port to access the Voice VLAN:
Setting this option to No (disabled) prevents the
•
attached PC from sending and receiving data on the
Voice VLAN. This setting also prevents the PC from
receiving data sent and received by the phone.
Set this setting to Yes (enabled) if an application that
•
requires monitoring of the phone traffic is running
on the PC. These applications include monitoring
and recording applications and network
monitoring software.
