Feature description
Call Waiting notifies a telephone user on an established call (internal
or external) that an external call is waiting to be answered. Meridian 1
proprietary telephones must have a Call Waiting key/lamp pair assigned
and a Class of Service that allows a warning tone. Call Waiting is applicable
to the Prime DN or any single appearance DN on the telephone. When
an external call comes into a Meridian 1 proprietary telephone and the
telephone user is on a call, the Call Waiting lamp flashes and a buzz sounds
through the telephone’s speaker.
To use Call Waiting, analog (500/2500 type) telephones must have a
Class of Service that allows Call Waiting and a warning tone. Two tone
bursts are received through the handset to advise an analog (500/2500
type) telephone user of a waiting call. Note that the two calls cannot be
conferenced together.
