Having installed a three handset beocom2 with pstn unit (old style) in my house, which works and looks excellent, I find that my siemens trio working along sidewhich has an answerphone facility switched on and set to six rings cuts in when I answer an incoming call on my beocom2s then records the whole conversation (not good!) after playing the outgoing announcement over the top of the exsisting conversation first. Any thoughts on how to stop the siemens system cutting in and obviously not registering the call being opened by another phone would be greatly appreciated. I realise this is more problem with the siemens set-up but thought I'd ask here for bright ideas..first
