Call Transfer Overview
The transfer feature allows you to redirect a connected call from your phone to another number. After call transfer, your call is disconnected and the transferred call is established as a new call connection.
Following are the different types of call transfers:
Consult Transfer and Blind Transfer—In Consult Transfer, a transferring phone user can redirect the caller to a different target address, after consulting with the target phone user that answers the call. That is, the transferring phone user will stay on the call until the target phone user answers the call. In Blind Transfer, the transferring phone user connects the caller to a destination line before the target of the transfer answers the call.
Most phones use hard keys or softkeys for Transfer. Both Consult Transfer and Blind Transfer do not require separate configuration. The difference between the two types of transfer depends on when the transferring party presses the Transfer button a second time. For a consult transfer, the transferring party presses the Transfer button after the target answers, while for a Blind Transfer, the transferring party presses the Transfer button before the target answers.
For SCCP-initiated blind transfers, Cisco Unified Communications Manager provides call progress indications in the form of ring-back to the transferred user.
Transfer On-Hook—In this type of call transfer, the user presses the Trnsfer softkey, dials the number to which the call will be transferred, and then presses the Trnsfer softkey again, or simply goes on-hook to complete the transfer operation. You must set the Transfer On-Hook service parameter to True. This service parameter determines whether a call transfer is completed as a result of the user going on-hook after initiating a transfer operation.
Both Consult Transfer and Blind Transfer use the Transfer On-Hook option.
Direct Transfer—This type of transfer allows a user to join two established calls (the two calls can either be on hold or in the connected state) into one call and then drop the initiator from the transfer. Direct Transfer does not initiate a consultation call and does not put the active call on hold. The user uses the DirTrfr softkey to join any two established calls and remove the initiator.
