PBX Features
BLF (Busy Lamp Field)A telephone may have a group of lights (LEDs) which indicate the status of extensions on your PBX. You can then see, at a glance, whose extension is busy, unavailable or free. Normally, you can press an associated button to call that extension directly.
CLI (Calling Line Identity)CLI or 'Caller ID' is where the number of the calling party/line is available to the called party so that you can see who is calling before a call is answered.
IVR (Interactive Voice Menus)An IVR is a system for automatically answering an incoming call, playing a pre-recorded message to the caller and then offering a selection of menu items, such as "press 1 for sales, press 2 for accounts".
Call forwardingCall Forwarding is a facility for redirecting an incoming call from its normally routed extension/destination to another destination or extension. Call forwarding can be applied to all calls, until the facility is switched off or can be selective, for example when the normal extension is busy/engaged ('forward on busy') or only after the call has been unanswered for a predetermined time ('forward on no-answer').
Call DiversionSee Call Forwarding.
Session MonitorA session monitor is a facility provided by a PBX whereby an operator or other user can get an instant real-time display or report of the PBX status, for example active extensions or calls.
Call TransferCall Transfer is the facility to transfer an active call on one extension to another extension. Call Transfer can be attended, whereby the original extension user announces the call to the new recipient before putting them through or unattended, whereby the original recipient hangs up immediately after transferring the call and the call rings the new extension directly.
CDR - Call Detail RecordsCDR is a list or log of calls made or received by extensions on your PBX, or by your PBX trunk itself. It will normally, at the very least list the time/day of call, destination and duration. It may also include extension numbers, Caller IDs and call cost.
IntercomNormally, any extension on a PBX can call any other by dialling its extension number (or pressing a hot key corresponding to that extension). The two parties can then speak to each other, which is known as an intercom facility. On an IP PBX, Intercom calls are carried completely over IP so the calls are free, even if the extension is on the other side of the world.
DND (Do Not Disturb)This is a facility whereby an extension is set to reject incoming calls and the phone will not ring until the setting is turned off again so that the user is not disturbed for the duration.
DID/DDIA DDI number normally refers to one of several phone numbers where each one is directed to a specific extension or department, in addition to their main incoming phone number. If a company therefore has several/many DDIs, a caller can then call directly to a department or extension without having to go through the main reception or other departments.
Call BarringCall barring is the facility to block calls based on rules which you select. You can, for example, bar all calls, so that a group or extension cannot dial any calls or block dialling of specific destination (e.g. mobile, international or premium rate numbers). Different rules can be set for different extensions or groups. Incoming call barring can also selectively block all calls or calls from specific locations.
Remote ExtensionA remote extension is one which is not in the same physical location as your IP PBX, main office or other extensions. It will be connected using IP over the Internet or through a VPN tunnel to your IP PBX. A remote extension on an IP PBX works just like a local extension, including intercom, hunt groups and BLF facilities.
Call pickup (Extension or Group)Call Pickup is a facility which lets you answer a call which is ringing on another nearby extension, even if it is not ringing your own extension. This is ideal for where a colleage at an adjacent desk has gone away from their desk for a moment.
VoicemailVoicemail is a facility for the PBX to play a pre-recorded message to callers and then let them leave a message. That message is then available to the person who was unable to take the call, either by listening from their extension handset when convenient or the message can be forwarded by email for listening elsewhere. Voicemail can take a message when an extension is busy or when unanswered after a period. Voicemail can be applied to individual extensions or groups.
MWI (Message Waiting Indicator)A Message Waiting Indicator is a light or indicator of some kind, typically on your phone which lights up to indicate the presence of a message left for you on voicemail. Once that message has been listened to or deleted, the indicator will turn off.
Music on HoldMusic or pre-recorded messages which play to callers when they are put onto hold.
