Diversion
QSIG Message Waiting
Indication
QSIG Call Transfer
QSIG Callback (Call
Completion)
Call Offer
Path Replacement
Description
Allows the system to send and receive the name of the caller; in turn, the called
party will see the name of the caller on the telephone display screen if the
appropriate Class of Service options are set.
Incoming calls are diverted to another destination as defined by the user when
the service is activated. This includes:
• QSIG Call Forward Busy
• QSIG Call Deflection
• QSIG Call Forward No Reply
• QSIG Call Forward Unconditional.
Users can set or cancel message waiting indications on the set of another party
to indicate that they wish to be called back.
A user can connect two other calls together, of the same basic service, as a new
call (there must be three parties). This feature does not support placing a party
on soft hold before making an enquiry call to another. This feature maps to the
Transfer portion of the MSDN/DPNSS Call Hold and Three-Party Working
Service.
Users can request a Callback when they reach a busy or unanswered station.
Callback with service retention is supported for the following Call Completion
Supplementary Services:
Completion of Calls to Busy Subscribers (SS-CCBS): users can set a Callback
against a busy station.
Completion of Calls on No Reply (SS-CCNR): users can set a Callback against
a station that doesn't answer.
Users can offer calls to parties at a busy destination. The busy user receives
indication of a call offer, while the calling party receives indication that a call offer
has been invoked. The called user has the choice of clearing the current call and
being re-rung, putting their current call on hold and accepting the offered call, or
ignoring the offered call.
Active calls, connected through the Q.SIG network, can be replaced with new
connections which are more efficient or cost effective (when possible). The
originating system requests the path replacement and the terminating system
makes the optimized call. None of the existing call path is used when path
replacement occurs. There must be an established call (a call that has been
answered) before this feature is invoked.
