Observing calls 

3. In the Station screen, assign a Service Observing button to the observer’s 

phone.

A service observing button permits users to switch between listen-only and 
listen-and-talk modes simply by pressing the button.

4. To activate the warning tone, type 

 in the Service Observing — Warning 

Tone field on the

Feature-Related System Parameters screen.

A unique 2-second, 440-Hz warning tone plays before an observer 
connects to the call. While the call is observed, a shorter version of this 
tone repeats every 12 seconds. 

In order for users to activate service observing by feature access codes, use the 
Feature Access Code screen to administer codes in one or both of the following 
fields:

■

Service Observing Listen Only Access Code

■

Service Observing Listen/Talk Access Code

When using feature access codes, observers must choose a mode at the start of the 
session. They cannot switch to the other mode without ending the session and 
beginning another.

Feature access codes are required for remote observing.

Refer to 

‘‘Service observing’’ on page 1483

 for detailed information on service 

observing.
