ARP: Address Resolution Protocol.
BLF/DSS: Busy Lamp Field/Direct Station Select. BLF indicates the status of another phone. DSS dials
another phone.
Caller ID: Service provided by some local telephone companies that supplies the calling party’s phone
number and name.
CSV file: Comma Separated Values file. The CSV file is a plain text file specially formatted to store
spreadsheet or database information. CSV files are used as a method for transferring data between
programs. For example, to load a phone book created in Microsoft Excel into your IP phone, save the
Excel file as a CSV file and upload it to the phone through the Web GUI.
DHCP: Dynamic Host Configuration Protocol. DHCP is a protocol that assigns dynamic IP addresses to
devices on a network. Each time the IP 706/IP 712 phone connects to the network, its IP address may
change. The DHCP keeps track of the address changes.
DID: Direct Inward Dialing number. Essentially a number assigned to an extension within a VoIP PBX.
The DID allows calls originating from PSTN to be routed to extensions within a VoIP network. Also, calls
originating from the VoIP network use the assigned DID numbers as their originating direct dial number.
Distinctive rings: Distinctive Rings are specific ring tones set to specified numbers, allowing the user to
recognize who is calling by the ring assigned to their number. Differing from internal/external rings,
Distinctive Rings apply only to specified numbers in the Personal Contacts list.
DND: Do Not Disturb prevents calls from ringing and paging over a speakerphone.
Duplex: Refers to the communication ability of two devices in a system. Half-Duplex means
conversation between two devices can only go one direction at a time; Full-Duplex allows for
communication in two directions simultaneously.
Firmware: The software that is embedded in a hardware device.
Function keys: The keys on the phone face that have an assigned function that does not change.
Handset: The hand-held part of the phone that contains the audio transmitter and receiver.
Headset: A handsfree device worn on the head that contains the audio transmitter and receiver.
HFAAI: Handsfree Auto Answer Intercom. The HFAAI feature enables the phone to answer calls
automatically (without ringing) when both parties have HFAAI activated on their phones.
ICMP: Internet Control Message Protocol.
Idle screen: The LCD display when the phone is in an idle state.
