- Caller ID/ Caller Identification (CLI/CLID)
-
- Is Caller ID available in the UK ?
-
- Yes. A detailed discussion paper covering most of the issues, including an
- appendix by the Data Protection Registrar and the results of a survey of
- public attitudes, was published as follows
-
- Consultative document : calling line identification / issued by the
- Director General of Telecommunications. September 1993. 20 pages.
-
- (contact Oftel for this)
-
- from the April 1994 BABT Newsletter
-
- CALLER DISPLAY SERVICES ON ANALOGUE PSTN LINES The draft SITS
- [Special Investigation & Test Schedule - ie. Specification]
- BABT/TC/128, which has been available for comment, will not be
- ratified by the BABT Technical Committee until OFTEL have
- resolved the position regarding competition between public
- network operators (PTOs).
-
- Other operator's networks are likely to offer similar services in the
- future at which time Caller ID will almost certainly be passed between
- networks.
-
- For BT, to use Caller Display you need a special telephone or display unit
- which show, and then store, the numbers of incoming callers. Call Return
- simply stores the number of your last incoming caller, and will work with
- any phone. You can dial 1471 to get a reading of the last number that
- attempted to ring (free).
-
- There are a range of free options for preventing their identity going
- forward on outgoing calls and blocking incoming anonymous calls. The
- simplest of these is the '141' service which blocks caller id going forward
- on a per-call basis. You can also have all calls blocked and then release
- per-call with '1470'.
-
- For more information on Caller Display and Call Return call 0800 801471.

- What PSTN phones support Caller ID?
-
- BT has one PSTN phone- the Relate 1000, that supports Caller ID.
-
- Early releases of this phone suffered from a problem where the unit's
- processor would 'hang', causing the Caller ID display to miss incoming
- calls until the handset is picked up. To fix this problem, ask BT to supply
- a phone with a serial number ending "B22" (or, presumably, later versions).
-
- Reports say that even the latest phones miss the occaisional call, but
- doesn't crash. Various ideas for the missing calls, including noisy lines
- between Exchange and handset, have been suggested.
-
- What ISDN phones support Caller ID, decoding and displaying it?
-
- DP2000 From BT - is an ISDN phone with analogue jack and RS-232 38K port It
- does CLI, MSN, stores last 10 CLI so you can return your calls and it looks
- OK. (Caller ID to ISDN costs UKP3.40 per quarter).
-
- I've seen a couple of ads in Exchange & Mart for Caller ID devices...
- anyone know if these really work ?
-
- No. They are EITHER boxes made to the USA standard (which was not adopted
- in the UK) or boxes that ask callers to input their number in MF tones, and
- then display what is input.
-
- Can I route a call to different devices depending upon the CLI?
-
- Yes, at least one such device exists and has been discussed
