What is the difference between "New call"and "Attended transfer" options.

[Yealink Support]

Hello,
1.Do you mean on your phone, you configured one DSS key as Transfer?
2.And in the webpage-Phone-Features-Transfer Settings-Transfer Mode via DSSkey
There are three options: New Call, Attended Transfer, Blind Transfer
3.Actually this setting is the same both on T3x and T2x phones with V70 firmware.
4.You can select Attended Transfer if you don't want to wait for dial timeout and press Transfer softkey.
5.The difference between New Call and Attended Transfer is, when you select New Call, you can change the number that you want to transfer to, you can press delete to delete the number and enter another number. While if you select Attended Transfer, the call can be only be transfered to the number that you configured in the DSS key.
