Recently purchased the trio handset, handset 1 on the base station works perfectly however handsets 2 & 3 have a problem, if I make an outgoing call I can hear them but they cannot hear me, if I receive a call they can hear me but I cannot hear them and the same happens if I use my mobile to call the handsets. I have registered the handsets and re-set the phones as advised by BT however the fault remains, in conversation with BT Help they quoted a fault code of 1600176 which means nothing to me. Has anybody had a similar problem or found a resolution to this, I have searched the manual but that did not provide an answer.
