Cloud telephony terms, in plain English

Every term you need to understand your cloud phone system, defined simply. No jargon, no assumptions.

Attribute

A property assigned to a user, such as their group, location or language. Voxbi uses attributes to decide how calls are routed.

Autoprovisioning

Automatic phone configuration. Supported desk phones set themselves up when they connect, with no manual handset programming.

Call flow

The path an incoming call takes through your call flow: who gets called, for how long, and what happens if no one answers.

Extension

An internal short-dial number assigned to a user or a function inside your phone system.

Indrasec router

A managed router that builds a secure, encrypted tunnel from your office network to the Voxbi cloud, so phones connect safely without complex firewall changes.

IVR (interactive voice response)

An interactive voice menu that lets callers choose options by pressing keys, for example "press 1 for sales, press 2 for support".

L2TP (layer 2 tunneling protocol)

A virtual private network protocol used to build a secure tunnel between your office router and the Voxbi cloud.

Music on hold

Music or an announcement that callers hear while they wait in a queue or during a transfer.

PBX (private branch exchange)

A private phone system that handles calls inside a business and manages its external phone lines. A cloud PBX does this from the internet instead of a box on site.

Queue

A waiting line where callers wait until an agent is free. A ring strategy decides who is offered the call first.

Ring strategy

How a queue distributes calls to agents, for example ring everyone at once, round robin, or offer the call to whoever has taken the fewest calls.

RTP (real-time transport protocol)

The protocol that carries the live audio and video during a call.

Schedule

A set of times that decides when a routing rule applies, such as office hours, evenings or public holidays.

SIP (session initiation protocol)

The protocol that sets up and ends internet phone calls between devices.

SIP carrier

A provider that supplies the trunks used to make and receive external calls over the internet.

SIP device

A hardware or software phone that communicates using SIP.

STUN (session traversal utilities for NAT)

A protocol that helps a phone discover its public internet address, so calls connect reliably through firewalls and home routers.

Twinning

A feature where an incoming call rings your desk phone and your mobile at the same time, so you never miss it.

Voice VLAN

A separate part of your office network reserved for phone traffic, which protects call quality and keeps voice separate from other data.

Voicemail

A recorded message a caller can leave when no one answers. Voxbi can also send it to you by email.

WebRTC

The browser technology that lets Voxbi make and receive calls in a browser tab, with no plugin to install.
