If connected to headset dock, microphone does not work. It's mute. Instead, it all works properly if I connect the headset to the receiver dock, and leave the receive disconnected. I tried the headset on different mitel phone and it always worked properly. Problem occour only when it is connected to a 5235 IP Phone. Thanks.
