Freefone interrogation - the ultimate listing

I have undertaken a massive dial through of LINKLINE (0800) numbers to be listed in this and forthcoming issues of ELEKTRIX. All were known to be in working order when this first issue went out - May 1990. Some you may have seen before - others you won't. I've simply collected all the known ones I could find which were still working and listed useful information for each.

Since there seems to be much going on with Voice mailboxes, computerdial, test lines, and PABX hacking lately I have included these too with comments where appropriate as well as the standard modem lines. Since on occasions a great many numbers 'side by side' have been engaged at the same time I have included this since it may give clues to the nature of the line-use should you wish to pursue these.

The ranges that I have dialled through myself have not always been in a logical fashion - but then it gets real boring dialling through 1000 dead numbers. So I try to vary it. But the results have been reasonable. If you have made any dials through 0800 or just modem wardials then please let us have the results so we can share them with others - it's also pointless two people dialling through the same ranges.

I hope these lists bring you much fun! Regards Pop
