[SIPForum-discussion] sip Call transfer

[santosh patra]

Basic difference between Unattended And Attended Transfer is 

Un-attended Transfer is Blind transfer means During the session between A and B, If A triggers REFER to C for For transfer then Stateful proxy or B2BUA will transfer the call to A and B2BUA will terminate the session between A and B.
But In Case of Attender Transfer the User puts current session on Hold, and interacts with New user then depend on the user is user wants to talk then User will initiate Refer.
