2-2 ROLMphone 300/600 Series User Guide
Making a Call
Before dialing a number or using a feature access code you must get a
dial tone. The dial tone is an indication that the system is ready to
accept your request.
You can get a dial tone in one of the following ways:
• by picking up the handset
• by pressing a line key
• by pressing the Speaker key
• by pressing the Transfer key during a call
Note: This guide assumes that your telephone has been set up at the
communications server to get a dial tone in the same ways as
ROLMphone telephones have on previous versions. If your
telephone has been set up differently, the ways to get a dial
tone may be different.
