The only way I've found with the Siemens that I have is to use the 
asterisk native features - So edit features.conf appropriately, I have:

[general]
xfersound            = beep     ; to indicate an attended transfer is complete
xferfailsound        = beeperr  ; to indicate a failed transfer
transferdigittimeout =   8      ; Number of seconds to wait between digits when transfering a call
featuredigittimeout  = 999      ; Max time (ms) between digits for activation. Default is 500


[featuremap]
blindxfer  => #1                ; Blind transfer
atxfer     => ##                ; Attended transfer
disconnect => #0                ; Disconnect

Then you need to make sure you use the 't' option in Dial() statements, 
then you dial ##, asterisk says 'Transfer', then you dial the extension, 
speak to them & hangup to make the transfer, or #0 to get back to the 
original caller.

It's a PITA, but it works on all phones regardless of their own features, 
buttons, etc. so I usually teach people that before the phone specific 
stuff.
