Concepts

BLF: a Busy Lamp Field is a light on an IP phone set used for telling whether and how an extension connected to set’s PBX is in use.

CDR: Call Detail Records are data registers that contain information about the calls (caller ID, called-party ID, start time, stop time, etc).

Client: a OneContactPBX client. Typically, this entity represents a company or company department. Each client is identified by its unique domain.

Client administrator: a user with privileges to manage configurations for a specific Client.

DDI: Direct Dial In is an external routable number typically known as phone number.

Dialing plan profile: a profile that defines a set of rules applied whenever some client extension places an outbound call.

Extension: a phone extension. Each extension has an unique address, valid within the client domain. An extension can be used in any SIP-compliant phone/softphone.

FMC: fixed-mobile convergence. See Fixed-mobile convergence.

Hunting group: a logical representation of a group of extensions.

IVR: an Interactive Voice Response.

Outgoing rule: a rule applied whenever an outbound call is placed.

PBX: a Private Branch Exchange.

Routing rule: a rule applied every time a routing operation is performed.

Routing profile: a profile that defines a set of rules applied whenever some routing conditions have been met (extension not available, extension busy, etc.).

Site: this is a logical representation of a physical client site/office.

SIP: Session Initiation Protocol, the de facto standard for IP multimedia communications.

SNMP: Simple Network Management Protocol, an Internet-standard protocol for managing devices on IP networks. Typical devices include routers, switches, servers, workstations and printers.

System administrator: a user with privileges to change OneContactPBX's global configurations and manage clients, sites and extensions.

Waiting queue: this entity represents the operation of parking a call. If OneContactPBX receives a call for a busy extension with waiting queue, then the incoming call will be parked (the caller will be listening to music). When the called extension becomes available, it will receive a call from the calling party. If the call is answered, the caller will be unparked and connected to the extension.
