I had to fiddle with other things to make this work (needed for the 
Siemens CP4600 SIP/DECT phone)

I found that the default timeouts were a bit tight for my likings (and the 
people who I was testing this with!)

So in features.conf I have:

transferdigittimeout =  8       ; Number of seconds to wait between digits when transfering a call
featuredigittimeout  = 999      ; Max time (ms) between digits for
                                 ; feature activation.  Default is 500

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

If it's still not working, are you sure the DTMF is being picked 
up/transmitted correctly? If it's in-band, is it a codec other than G711? 
(which might give you problems)
