Sir: BT appears to have reinvented "call waiting" several times in its brief existence, now apparently ending up back where it started (Letters, 29 October).
At one point it did something very like what is recommended by Mark Trevorrow - that's when I gave it up. If the recipient chooses not to answer, the caller, hearing only a ringing tone, assumes there is no one there, or there is but they won't answer. For a small business like mine that is disastrous.
Perhaps the answer is to give the customer a choice - I seem to remember that's what privatisation of BT was all about.
