snom D725 blf + call pickup + transfer = huge problem

[link611]

Hi there,

we use snom D725 phones with blf function keys, we also use call pickup on those fkeys:

fkey6: blf sip:[email protected];user=phone|**

(** = call pickup)


now the freaky stuff: if extension 11 is ringing and i try to transfer a call to that function key (i am on phone, ext 11 is blinking, i press transfer -> fkey6 (ext 11))
then the incoming call from ext 11 and the one which i tried to transfer getting connected together.


that is pretty bad.


is there any configuration which can prevent this problem


Greetings
