1. A network device adapted to process a call between the network device and a first other network device, the network device comprising:
- a user interface adapted to receive a user input requesting a call transfer to a second other network device; and
a call transfer function responsive to the user input to deliver call transfer functionality by, upon receipt of the user input;
a) initiating a connection from the network device to the second other network device; and
b) sending a first message to the first other network device containing a reference to the second other network device.

Abstract
In a call transfer of a call there is an original calling network device, an original recipient of the call, and a transferee of the call. Systems, network devices, and methods are provided for delivering local call transfer functionality. Each network device is capable of functioning in the capacity of any one or more of the above three roles, namely, originator, original recipient, and transferee by providing local call transfer functionality. There is no requirement for central processing equipment used to provide local call transfer functionality for transferring calls.
