Great! Can connect two phones on my Livebox ...

With this "Lindy 75109 ADSL filter-separated two female RJ11 jacks on one side and a male RJ11 on the other - White" plugged into the blue one of my Orange Livebox RJ 45 therefore also receives the male RJ11 what Lindy I can use my old landline broadband in one room and my new mobile unit on base and battery in another room without a problem and at the same time during the reception or during the call by plugging them into each one of female outlets Lindy said. So that's what I needed! I do not see loss of reception or transmission, just a feedback too if I approach the laptop of our old position won by my wife to participate in the same conversation, normal. (I was forced to do so following a recent update by Orange Livebox and removed the purple socket to which I plugged the second post) And so actually it works better than before since it to each his post accessing the communication, which was not the case before, because it was either get one or the other position. An area for improvement would be to lengthen the cable 5 cm. If so I recommend that Lindy for the same use than mine, I use it for over a month is great and I do not see why it would not last! Fast delivery, product not very expensive and seemingly very robust design and aesthetic.
