Attended Transfer Procedure on Grandstream phones

Attended Transfer Procedure on Grandstream phones

If a call is answered on one extension and the caller wants to speak with another extension user, the person answering the call has two general options for how to proceed with getting the call to the intended party.  A "Blind Transfer" means that when the transfer is executed, the Protel PBX releases it from the phone that answered it and immediately sends it to a different phone, where it is treated just like a new incoming call.   If the transferring party needs to get permission from the intended recipient before sending the call to them, that procedure is called an "Attended Transfer"
In this article, we will show two different ways to execute an Attended Transfer using a Grandstream 2170 IP phone. All of the Grandstream models that start with GXP21xx use this process.  
Method A:  Shortcut method    To use this technique, the transferring phone must have a BLF (Busy Lamp Field) or Speed Dial button on their phone that is assigned to the intended recipient.
Step 1:  The call has been answered and is active on one of the phone's line buttons. 
Step 2:  The user has determined that the caller wants to speak to Kevin.  Since this phone has a BLF button programmed for Kevin, the next step is to press the BLF Key for Kevin - without pressing any other keys first.  This puts the caller on hold and establishes a new call to Kevin.

If Kevin agrees to take the call, the transferring user presses the Transfer Soft Key, then presses the blinking line button where the original call is on hold.  

If Kevin declines to take the call, the transferring user needs to terminate the call with Kevin and return to the original call to take a message.  This can be done quickly on the phone:  Press the End Call button, then press that same key again.  When the End Call button is pressed, the function of that key instantly changes to "Resume", which reconnects you to the call on hold:

Method B:  Standard Method    For phones that do not have a BLF key already set up with the destination extension, follow these steps to execute an attended transfer:  This method can be used on any phone, even if it is equipped with appropriate BLF keys.
Step 1:  Press a new line button.  The first call is placed on hold and you can now use the keypad to dial the intended recipient.
Step 2  Enter the Destination extension - or external phone number - on the keypad
Step 3  Press the Transfer button.  This initiates the call to the user - but the transfer has not actually happened yet
Step 4  Press the blinking line button to connect the call to the destination - OR - press End Call and Resume (they are the same button) to return to the call on hold.
