Step by Step
Making calls – the basic
functions
You can use your handset to make both internal and ex-
ternal calls.
Internal calls are calls that
• you make within the range of a communication sys-
tem, for example, within your company,
• you make between networked communication sys-
tems, for example, to different company locations.
External calls are calls that you conduct with users of
the public telephone network.
