This document describes the procedure you use to configure Cisco CallManager in order to allow customers to dial the operator by composing 0 (zero). Though you can achieve the same result with the configuration of the speed dial to dial the receptionist or the main number, customers are often dial 0 for the operator. This document explains how to configure the system to allow for this situation.

Complete these steps:
Select Route Plan > Route Plan Report and verify there is no other pattern that starts with 0 (zero).
Select Route Plan > Translation Pattern > Add New Translation Pattern.
Create a Translation Pattern 0 and specify the Called Party Transform Mask as the phone number of the operator. In the example in the Translation Pattern Configuration window, 4001 is the operator number.
Note: With Cisco CallManager 4.0 there are extra options such as MLPP Precedence and Connected Party Transformations, which can be left at default values.
The Translation Pattern Configuration window example assumes there are no Calling Search Spaces or partitions. However, many deployments make use of these.
The general rule of thumb is to ensure that the Calling Search Space for the Translation Pattern includes the partition of the directory number of the phone that is called. In this case, there is a Calling Search Space test which is selected from the drop-down menu in the Calling Search Space field.
The phone directory number 4001 belongs to the Partition called partition 2. Therefore, the Calling Search Space, test, needs to include partition 2.
Note: For Cisco CallManager 4.0 the screen contains additional options such as MLPP Alternate Party Settings, Multiple Call / Call Waiting Settings, and so forth, which can be left as default.
