While handling a call, it may be necessary to pass the phone call along to a user, call queue, or an external phone number. This can be done through transferring. 

While handling a call on your Grandstream handset, there are three different types of transfer that can be utilized depending on how exactly the call needs to be transferred and handled:

1. Blind Transfer - Transfer a call directly to another person without talking to that second person.  This is method of transferring is also referred to as a “cold” or "unassisted" transfer.
2. Attended Transfer - Speak with the person being transferred to before completely transferring the call.  This method of transferring is also referred to as a “warm” or “assisted” transfer.
3. Voicemail Transfer - Transfer a caller directly to a general mailbox or the voicemailbox of another user.

Blind/Cold Transfer

When you use a blind transfer, you transfer a call without speaking to the party that the call will be transferred to. The person receiving the transfer will need to answer the transferred call.

To perform a blind transfer…

1. While on an active call, press the Options softkey and select Transfer.
   
   

   Note: The caller will be placed on hold automatically where they will listen to music on hold.

    
2. On the Dial screen, dial the extension or phone number you want to send the call to.
   
3. Press the Transfer softkey.
    
4. Select Blind Transfer.
   

Attended/Warm Transfer

Perform an attended transfer if you want to talk to the person receiving the transfer. This can be a great way to check that the person being transferred to is actually ready to receive a transfer. If the second person answers your call and an attended transfer is completed, the caller will be directly connected to the second person without the need for them to answer the call.

1. While on an active call, press the Options softkey and select Transfer.
   
   

   Note: The caller will be placed on hold automatically where they will listen to music on hold.

    
2. On the Dial screen, dial the extension or phone number you want to send the call to.
   
3. Press the Dial button to start the second call.
   

   Quick Tip: You can also press the Transfer softkey and select New Call to start an attended transfer.

    
4. Wait for the second person to answer and talk to them as needed. 
   
   

   Quick Tip: If the person receiving the transfer needs more information, you can Swap between the calls by pressing the Options softkey and selecting Swap. 

   

    
5. Press the Options softkey again and select Transfer to complete the transfer.
   

Transfer to Voicemail

In some instances, a caller may need to reach out to a user that is not able to accept a transfer at the moment. If this is the case, the caller can instead be transferred to a user's voicemailbox to leave a message.

To transfer a caller to a user's voicemailbox…

1. While on an active call, press the Options softkey and select Transfer.
   

   Note: The caller will be placed on hold automatically where they will listen to music on hold.

    
2. On the Dialing screen, dial 03 and the mailbox's extension number.
   

   For example… To transfer the caller to the mailbox of user 100, dial 03100. To transfer the caller to general mailbox 500, dial 03500.

    
3. Press the Transfer softkey.
   
4. To complete the transfer, select Blind Transfer.
