- I don't think this will be possible. As I understand it, you won't have
- the option of blocking CLID from payphones. They're anonymous enough as
- it is, and a persistent malicious caller who moved round payphones could
- avoid any kind of detection if you could block payphone CLID; at least,
- it would require a good deal more work on BT's behalf to track them.
- It would also be inconvenient if there's someone you regularly need to
- speak to who has CLID permanently blocked; you wouldn't answer the phone
- on no-ID.
-
- The options for blocking on exchange lines will probably be either
- per-call or per-line for domestic lines; that's what the trial has, I
- believe. I'm don't know how the interface for PABXs will work;
- presumably CLID can be passed on.
-
- In the future the full set of extras should be available: selective barring,
- selective acceptance, different ring tones, selective forwarding and
- so on. I'm not sure if selective call-waiting is one of them (``if it's the
- office or my partner, beep me to tell me there's a call waiting; otherwise
- give engaged tone'').
-
- My opinions, not BT's. I don't work on direct service provision, or
- exchange technology, or anything like that.

- Tim.
