[Asterisk-Users] Initiating a transfer from an analog handset?

[Jamin W. Collins]

Is there a way to initiate a transfer using an analog handset?  For 
instance I'm looking for a way to do something like the following:

External call comes in and is answered by user A.  After talking to the 
caller they determine that the caller really needs to speak to user B.  
Is there any way for user A to initiate a transfer to user B, using 
only their analog handset?

Now to make things possibly more complex, is the above still possible 
if the analog handset is connected to a Zhone Zplex channel bank?
