4.1 Call transfer
Access to the ‘Call transfer’ service is established via subscriber port settings menu – ‘Ports
conf.’ - by selecting ‘Attended calltransfer’ value or ‘Unattended calltransfer’ in the ‘Flash transfer’
field.
'Attended calltransfer' service allows you to temporarily disconnect an online subscriber
(Subscriber B), establish connection with another subscriber (Subscriber C) and return to the previous
connection without dialling or transfer the call while disconnecting Subscriber A (a subscriber that
performs the service).
'Attended calltransfer' service usage:
While being in a call state with a Subscriber B, put him on hold with short clearback flash (R),
wait for 'PBX response' tone and dial a 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 – 3-Way Call;
- R clearback — call transfer. Voice connection will be established between Subscribers B
and C.
