PLAR (Hotdial): Overview

The Private Line Automatic Ringdown (PLAR) feature, also called Hotdial, automates the Unified CM configuration required to set up PLAR for a phone. The PLAR feature provides an administrator with a single interface and workflow for the management of the following elements of Unified CM:

  • RoutePartition

  • CSS

  • TransPattern

  • Phone

  • Line

  • SIP Dial Rule

The feature further provides an administrator with:

  • A simplified user interface to select a Phone that must be enabled for PLAR, a destination number, and the destination CSS.

  • The orchestration of a workflow to create the necessary Unified CM partition, CSS, Translation Pattern, and so on, and to apply these to the relevant Phone and Number.

To configure an existing phone for Hotdial, the user selects a pre-existing device and indicates that the device is a Hotdial device.

As soon as a PLAR configured phone goes off hook (or the NewCall softkey or line key gets pressed), the phone immediately dials a pre-configured destination number. The phone cannot dial any other number except the Hotdial destination that gets configured for PLAR.

The PLAR configuration can be added or deleted, but not modified.
