Technology is utterly irrelevant, the industry has always been able to trace calls.
Not at all. Last year I received an abusive call and the number was withheld. I telephone BT and they informed me that with out a number there was nothing they could do to help me
The BT Nuisance Call Bureau would not deploy their most advanced capabilities in such a case. This is a matter of policy, not capability. If the call in question had, for example, been an accurate warning about a bomb, the call would have been traced.
The standard call tracing facility would be deployed if there were a pattern of such calls. This enables the recipient to signify that the most recently received call is to be logged. The number of the caller (even if "withheld") is thereby made available to the NCB who can identify the caller under a reciprocal arrangement with the originating telco and pass the information to relevant bodies, e.g. the Police, and (since a policy change was made in 2003) Ofcom.
I do not fully understand the detail, but I am happy to accept that there are probably good reasons (probably cost, which bears on the price of telephone services,) why this logging facility is not provided to all at all times. It is provided where deemed necessary for period of one month, without charge. It has been used to identify Silent Callers, however Ofcom generally does little with the information.
The point I seek to make is that if an abusive caller does not identify themselves during the call, it is unlikely that they would comply with a requirement to provide a number when making abusive calls. I accept that the moral right to withhold their identity should be forfeit if the call is abusive, but as with other similar situations it is not easy to apply such a principle. Anyone undertaking a burglary should be required to wear a striped T-shirt and an eye-mask, carry a bag with the word "swag" on it and give their name and address to anyone challenging them, saying "its a fair cop, gov". Its a great idea, but I cannot see how it would work.
