Call Transfer allows you to transfer the call you're currently on (the live call) to another phone number, like to a cell phone or to a friend's house.
To transfer a live call:
While your call is in progress, tell the caller you are going to transfer them to another number.
Press and quickly release the switch hook. Don't hold the switch hook for more than a second or you'll hang up on the caller.
Dial the number to which you want the call to be transferred. Wait for the call to be answered to let that party know you are transferring a call to them.

You may simply hang up while the second number is ringing and the call will be seamlessly transferred. Note: If transferring a call to a 1+ number (long distance), you will be charged for the long-distance call for the entire duration of the transferred call.
