asterisk users - Jul 2012 - weird dect beheaviour multiple handsets

I have this very specific problem with two dect sets. Problem that I 
have is one-way audio, in this very rare situation.

I am calling with a Siemens N510 with C610 handset to Panasonic 
KX-TGP500 with KX-TPA50 handset. This gives me problems when I am 
calling to a SIP account that is configured to ring all handsets. Then 
when one handset answers, I only hear the panasonic, but they don't hear me.

When I call to an extension that is configured to ring only one handset, 
I don't have this problem.

When I use panasonic on both sides, or Tiptel -> Panasonic, I don't have 
this problem as well.

I am breaking my head what this could be. Any idea's?
