Call Waiting
Primary Rate Interface
(PRI) and T1
Call Waiting is provided on PRI lines at extensions so programmed. The
call-waiting tone is not blocked from PRI at an extension. Until the call is
answered, answer supervision is not returned to the network and the
caller hears regular ringback instead of call-waiting ringback.
Call Waiting does not work with data calls.
Recall/Timed Flash
If Recall is used while a user is hearing special ringback, the call is
disconnected and the user hears inside dial tone.
Reminder Service
Reminder calls are not eligible for Call Waiting.
SMDR
In Release 4.1 and prior systems, SMDR does not begin measuring the
duration of a call-waiting call until the call is answered. In Release 4.2 and
later systems with the Talk Time option enabled, timing for calls to Auto
Login and Auto Logout calling groups starts as soon as the system
detects the calls.
System Access/
Intercom Buttons
An extension is considered busy when all SA or ICOM buttons (excluding
SA Originate Only or ICOM Originate Only) are in use. A multiline
telephone user can dial the Call Waiting feature code to pick up a waiting
call only when an SA Originate Only or ICOM Originate Only button is
available.
Transfer
A user with no available buttons to receive a transferred call hears the
call-waiting tone when a co-worker uses the Transfer feature to transfer a
call, even if Call Waiting is not activated.
A call received by using call-waiting pickup can be transferred only if an
SA or ICOM button on which to transfer the call becomes available.
