Introduction

This document discusses how to configure a Cisco IP Phone for Private Line Automatic Ring-down (PLAR) or Hotdial with Cisco CallManager. With PLAR configuration as soon as the phone goes off-hook it dials a pre-configured number. This be done by making use of calling search spaces (CSS), partitions, and translation patterns.

Configuring Cisco CallManager

In this section, you are presented with the information to configure the features described in this document.

Steps for configuring PLAR

In order to allow the phone to automatically dial a pre-configured phone number when the user goes off-hook, a CSS is configured with a partition that contains a translation pattern with a blank translation pattern string. This results in Cisco CallManager immediately matching this pattern. The translation pattern then transforms the called number (i.e. none) to the destination number (Hotdial) where we want the call sent.

Note: Since a telephone configured for PLAR dials a pre-configured number when it goes off-hook, you cannot use PLAR phones to dial any other numbers. For example this is a typical configuration in hotel lobbies.

1. Create a partition.

   From the Route Plan menu option click Partition and then Add a New Partition. Fill in the required details and then click Insert.

   

2. Create a CSS.

   From the Route Plan menu option click Calling Search Space and then click Add a New Calling Search Space. Fill in the required details and select the partition you created in Step 1 by using the arrows from the Available Partitions field, then click Insert.

   

3. Create a translation pattern.

   From the Route Plan menu option click Translation Pattern and then click Add a New Translation Pattern. Select the desired partition name and CSS that were previously created in Step 1 and Step 2. Finally, under Called Party Transformation Mask, enter the Hotdial number that you want the phone to dial when it goes off-hook. Click Insert.

   Note: Ensure that the Translation Pattern field is left blank.

   

4. Finally, you need to select the CSS that you configured in Step 2 for the PLAR phone's CSS.

   This is done by clicking Phone under the Device menu option in Cisco CallManager and then selecting the PLAR phone.

   

Verify

This section provides information you can use to confirm your configuration is working properly.

To verify that the above configuration was performed correctly take the phone off hook. The phone should automatically dial the number 2006.

Note: Ensure that the Hotdial number belongs to a partition that is in the PLAR phone's CSS, HotdialCSS
