A call-waiting tone is heard only by the person receiving the call and not
by other conference participants. If the conference originator reaches a
busy extension, hears the call-waiting special ringback, and tries to add
the call to the conference, the system returns a busy tone. To drop the
busy tone from the conference, the originator presses the Drop button
and then the line button used to call the busy extension.
A call to a sender with Call Waiting activated goes to Individual and/or
Group Coverage first. If all coverage points are busy, the sender hears
the call-waiting tone.
Changing the status of Coverage On/Off to On after hearing the
call-waiting tone does not force the waiting call to coverage receivers but
sends subsequent calls to coverage.
Call Waiting does not work with data calls. The call appears to wait but
does not return to the extension when it becomes available. This feature
should be disabled at video systems and data extensions.
At a passive-bus MLX telephone, Call Waiting requires one of the
B-channels needed for a 2B video call and should be used only when the
video system is not active on, or receiving, a call.
When a user has a call waiting,
Call Waiting does not apply to forwarded calls because the system tries
the destination extension instead of the forwarding extension. However, if
the call is not forwarded for any reason (for example, the line/trunk
selected is an unreliable loop-start line), Call Waiting functions normally.
In Release 4.1 and later systems, a user with no SA or ICOM buttons
available and with Forward or Follow Me turned on does not hear the
call-waiting tone when a call is forwarded using the Forward on Busy
enhancement. Instead, the caller hears ringback.
Calls made to a calling group are not eligible for Call Waiting because the
calls ring into the calling group's queue. However, Call Waiting can be
used for calls to individual members of the calling group.
A person with all calls on hold cannot hear the call-waiting tone.
Call Waiting can be activated for a HotLine extension, but the telephone
cannot put the current call on hold and pick up a waiting call. Instead, the
user must hang up the current call and wait for the call-waiting call to ring.
Call Waiting cannot be used for Group Paging calls to busy extensions.
A user does not hear a call-waiting tone for a call received on a personal
line unless the business subscribes to a call-waiting service from the local
telephone company.
Pickup features cannot be used to answer a waiting call at another
extension.
