Call transfer is a call re-arrangement of an existing call in which one party is replaced with another party. Initially, the transferor is in an active call with the transferee. Then the transferor initiates a call transfer to the transfer target. Finally the transfer target gets connected to the transferee.
Transferor, transferee and transfer target may be within the Enterprise system or behind the Service Provider.
The following graphic depicts an example call transfer scenario with two call transfer participants within the server and one party is behind the Service Provider. Any other combination of call transfer participants within the Lotus Sametime Unified Telephony server or behind a Service Provider is possible.
