Transfer a Call - Attended and Unattended Transfers (QuickStart)
Sample name: CallTransferBasic
Sample location: %ProgramFiles%\Microsoft UCMA 3.0\SDK\Core\Sample Applications\QuickStarts\CallTransferBasic
Description
This sample involves communication between three users; a transferor, a transferee and a transfer target. The sample logs in as the transferor, who is the user who receives an incoming audio-video call from the transferee, logged onto Microsoft Lync 2010.The transferor accepts the call from the transferee, and initiates a transfer to the transfer target. This sample demonstrates the ATTENDED transfer-type; hence after the transfer completes, the initial incoming call is disconnected.
The user has the option of opting for attended or unattended transfers by changing the transfer-type in the code.
The difference between attended and unattended transfer is that unattended transfers begin the transfer (send the REFER to the caller) and terminate the initial call on receipt of the transfer request response (202-Reply) from the caller. Attended transfers, on the other hand, wait to terminate the call until the transfer either succeeds or fails. The application prints logging to the console, and then quits, shutting the platform down normally.
