300 Call Waiting/Internal Call Waiting
Idle Extension Notification
This feature can be used even if the Call Forward/Hunt Override Via FFC
feature is activated. When a busy set is encountered, it is possible to place
an IEN request against the set.
ISDN Night Service
If a call is diverted to a third-party operator Night DN that is busy, Call
Waiting may be activated (if equipped). The call to the third-party operator
circuit switched network is released.
ISDN QSIG/EuroISDN Call Completion
On an Analog (500/2500 type) set, Call Completion notification waits until
the set has finished an active call. If Call Waiting is configured on a set,
notification is presented after the Call Waiting call. If an additional call is
queued while Ring Again free notification is waiting on a set, the waiting call
takes precedence over the Call Completion notification. An established Call
Completion call is also queued if a set has Call Waiting feature equipped
and is occupied on another call.
Message Center
Call Waiting calls are not forwarded to a Message Center.
Multi-Party Operations
A user of an analog (500/2500 type) telephone can answer a Call Waiting
call, thereby establishing a consultation connection. The user can dial
control digits, as normal. To toggle the calls, the toggle control digit must be
used rather than a switchhook flash.
Multi-Party Operations
An analog (500/2500 type) telephone may be assigned both CWA and TSA
Classes of Service. The user can establish a Consultation connection by
answering Call Waiting during an active established call. If this is done,
Control Digit features (CNFD, TGLD, and DISD) are available. Note that
Programmable Control Digit TGLD, rather than a switchhook flash, is used
to toggle the calls. Operation with XFA Class of Service is unchanged.
The Three-party Service feature changes the operation of Call Waiting for
all analog (500/2500 type) telephones as follows (regardless of whether the
sets have TSA Class of Service. If an analog (500/2500 type) telephone
user activates Waiting during an active call so as to establish a Consultation
connection, and if the user goes on-hook during the Consultation
connection, the operation is treated as an AOCS misoperation. This
recovery of misoperation will take place even if the MPO package is not
equipped. In this case, the controlling party is re-rung by the held party
regardless of the CCDO and the recovery of misoperation options.
