Making Calls

This section describes ways to make calls on your 53i phone, using your 
handset, speakerphone or headset.

Dialing a Number

First, take the phone off-hook by:

• pressing  

or

• pressing a line/call appearance button.
At the dial tone, enter the number you wish to call. If you are unable to 
make calls within certain area codes, check with your system administrator 
for any toll restrictions placed on your extension that may restrict your 
access to long distance area codes or dialing prefixes.

When your party picks up, a timer appears on your display that records the 
length of your call. 

Using Handsfree Speakerphone

The handsfree feature allows you to speak to someone without using the 
handset or headset. Your phone must be in either the Speaker or Speaker/
Headset audio mode. You can set your desired audio mode using the 
Headset Settings option from the Options list. For more information, see 
the section "Customizing Your Phone" in the 53i Installation Guide.
