Using Network-based Call Transfer
This call transfer method is used when you want to transfer a call
without tying up two lines on your phone system. It uses the
AccessLine network to transfer the call instead of the phone
system.
1. Receive a call on your Conference Phone
2. Touch #5 to start the transfer (this will place your caller on
hold)
3. At the dial tone, enter the extension or phone number you
want to transfer the caller to
4. When the transfer party picks up the phone, touch #5
again.
5. All three of you will be connected.
6. Hang up and the two parties are connected (without tying
up any of your lines)
If the transfer party does not pick up the phone, touch #6 to return
to the original caller.
