Enter the digits and press the SEND to transfer the call with user B to User C. When user C’s phone rings, the phone interface of user A is shown in figure 43. If user C answers the call, user A will automatically go back to the idle screen, which indicates the successful transfer. 5. User C’s phone will ring, the phone with CID function will display user B’s number on screen as the caller. --------------------------------------------------------------------------------------------------------------------- Note: 1. If inputted the wrong digits, press the button to delete the digit one by one, or long press the button to empty all digits. 2. Users could tap on Back icon to go back to the active call interface if wants to cancel transfer. --------------------------------------------------------------------------------------------------------------------- ATTENDED TRANSFER There are two ways of attended transfer: Call Forward and Call Transfer. Firmware Version 1.0.1.x GVC2500 User Guide Page 46 of 88 CALL TRANSFER 1. User A and user B are in an active call. 2. User A presses the button to add a new line with user C.
