Call transfer
Call transfer service may be performed locally using gateway resources, or remotely using resources of a
communicating device. If the service is performed using resources of a communicating device, the access to
'Call transfer' service is established via subscriber port settings menu—
'VoIP' -> 'Line configuration'
—by
selecting
'Transmit Flash'
value in
'Flash operation mode'
field. Service process logics in this case will be defined
by the communicating device.
When
'Call transfer'
service is performed locally using gateway resources, the access to this service is
established via subscriber port settings menu—
'VoIP' -> 'Line configuration'
—by selecting
'Attended
calltransfer'
or
'Unattended calltransfer'
in
'Flash operation mode'
field.
'Attended calltransfer'
service allows you to temporarily disconnect an online subscriber (Subscriber A),
establish connection with another subscriber (Subscriber C) and return to the previous connection without
dialling or transfer the call while disconnecting Subscriber B.
'Attended calltransfer'
service usage:
While being in a call state with the subscriber A, put him on hold with short clearback flash (R), wait for
station response signal and dial subscriber C number. When Subscriber C answers, the following operations will
be possible:
–
R 0 – disconnect a subscriber on hold, connect to online subscriber;
–
R 1 – disconnect an online subscriber, connect to subscriber on hold;
–
R 2 – switch to another subscriber (change a subscriber);
–
R 3 – conference;
–
R clearback—call transfer; voice connection will be established between Subscribers A and C.
