Call Logging FAQ

                Call Logging - Frequently Asked Questions

1. What is Call Logging?

It is method of recording all dialled digits, call duration, start and
finish times, and type of call - i.e. incoming, outgoing, and whether or
not such calls were answered or not. It is referred to as "Call Logging" by
British Telecom, and "metering" by government agencies.

2. Who uses it?

British Telecom investigating telecom fraud, unwanted calls, as well as
snooping on its own employees whom it suspects of abusing granted facilites,
such as voicemail.

Also basically all Government agencies - e.g. State Police, Security
Services (MI5, MI6), GCHQ, NCIS, Customs & Excise and so on.

3. For what purpose?

It provides an accurate record of all calling patterns of an individual.
While some of this data is now available on modern digital exchanges, it
enables even digits *after* connection to be captured. From this a picture
of an individual's personal and business associates can be constructed,
which helps in building a case against an individual.

Such evidence can therefore be of great use in a court case. It has been
especially useful to BT Security in cases of dial through fraud.

4. What controls are there on its use?

None. Yes. None! There are no regulations regarding when it should be used,
for how long, or for when it should be disconnected. This is in breach
of the European Convention of Human Rights, and as such both all
British government agencies that use it, and British Telecom are effectively
operating, in a similar way, as one would have expected Soviet Russia to.

Scottish police did draw up a code following the "Ferresgate" affair, which
said that it should only be used in "serious" crimes. English police,
mindless thugs that they are, have no such policy. The same applies in
Northern Ireland and Wales.

As there is no statutory basis for call logging, there is no right to
appeal, unlike if you are being voice logged. There have been several
appeals under the tribunal setup under the 1985 act, and none have been

5. How much is it used?

To a huge extent. The old estimate was 35,000 per year, but as use has been
growing to such a huge extent in the last ten years, this figure is likely
to be nearer 40,000 by now.

6. How do I find out more?

The entire documentation is on this web site, thanks to a former BT
employee who supplied a photocopy of the two existing versions along with
a whole host of other information. Study both versions carefully, and
discover how it all works. Remember that these are not up-to-date totally,
so some of the specifications now may be inaccurate.

7. What is the difference between the two versions?

The version 1 is the total guide - including how to program the MONOLOG.
The second version is just an Installation Guide, but is included as it is
more recent and contains additional data.

8. Why is this web site available?

Quite simply, as long as metering remains a breach of fundamental human
rights - which it currently is - this web site will remain active. There
can be no grounds for this not to be the case, except by those groups whom
wish to see democracy replaced by facism. Many of course wish to see the
current situation unchanged, such as the State Police and British
Telcommunications. Expect nothing to happen in the near future.
