1.71.1 Feature Description
Supervised call transfer is a feature that enables a controller (party A) already in a call
with another party (party B) to transfer the call to a third party (party C). The end result is
a call between party B and party C. This feature is a common requirement in IVR and
voicemail applications.
1.71.1.1 Basic Call Transfer Scenario
The sequence of events in a supervised call transfer scenario is described below. It is
assumed that party A and party B are already in a call.
1. Party A hookflashes party B, placing the call with party B on hold. This call is referred to
as the “held” call.
2. Party A dials party C and waits for an answer.
3. Party A notifies party C that the transfer is about to take place. This call is referred to as
the “consultation” call.
4. Optionally, party A hookflashes party C and notifies party B of the transfer.
5. Party A hangs up.
6. Parties B and C are connected and the transfer is completed.
The sequence is shown diagrammatically in the following figure.
