Call Waiting
When Selective Callback is used to queue a call at an extension that
has Call Waiting, the user with call waiting hears the call-waiting tone
and the call is queued until the extension becomes available.
A user with no available buttons to receive a transferred call hears the
call-waiting tone when a co-worker uses Camp-On to transfer a call,
even if Call Waiting is not activated.
A call-waiting tone is only heard 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 queue
but does not dequeue when the extension becomes available.
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 trunk selected is an
unreliable loop-start trunk), Call Waiting functions normally.
Calls made to a calling group are not eligible for Call Waiting because
the call rings 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 cannot be used for Group Paging calls to busy extensions.
A user does not hear a call-waiting tone for calls 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.
Reminder calls are not eligible for Call Waiting.
SMDR does not begin measuring the duration of a call-waiting call until
the call is answered.
