The phone is good quality and the sound between phones is good.
BUT - These phones will NOT answer a call on a Virgin telephone line
They will on a BT line (I tested this)
Virgin line = a DSL standard over co-axial line.
Its a different tone than BT and these phones just stall -they do not play the message, nor will they record. Confirmed with Phillips UK on two different, new, sealed, machines.
Trust me, I'm an expert.
(The Virgin line is not ADSL, not multiplexed, nor VOIP for all the smarties and Phillips tech helpline, its a standard DSL line)
