Gigaset HDSP – telephony
with brilliant sound quality

phone supports the

of a broadband connection.

In handsfree mode, you use the microphone
and speaker on the base rather than the
receiver. For example, this allows others to
participate in the call.
In open listening mode, you hold the con-
versation via the receiver and also activate
the speaker on the base (receiver and hands-
