'Unattended calltransfer'
service allows to put an online subscriber (Subscriber А) on hold with a short
clearback flash and dial another subscriber's number (Subscriber С). Call will be transferred automatically when
Subscriber B finishes dialling the number.
Figure below shows
'Unattended calltransfer'
service operation algorithm:
‘Local calltransfer’
service
allows you to
transfer call through the gateway without sending the external
REFER message if C subscriber is a local
RG 5400
client and its call was directly perfomed with ignoring of the
proxy server. If C subscriber is external or local client which was called via proxy server, ‘
Local calltransfer’
service operates like ‘
Attended calltransfer
’ and call transfer is performed by sending REFER message to the B
subscriber
