We are seeing an interesting trend lately - companies finally ceasing their fax line. We see almost no faxes ourselves, but it is interesting that fax machines and lines are actually being removed finally. It was a lot slower than the demise of telex, probably because it is a lot cheaper to keep a fax machine going.
There is, however, a problem, and this is why we are seeing this. People (typically accounts departments) finally decide to cease a fax line without realising that this is the line on which the broadband is supplied. In many offices the fax line is one of the few analogue lines they have suitable for broadband as they have ISDN phone systems still. (The move from ISDN to SIP is happening slowly).
The first anyone hears about it is when the internet stops working. The end user then has to (a) get the BT line reinstated (usually reasonably quick), but then has to (b) wait for the broadband cease to close (c) order new broadband, and maybe (d) pay for an expedite on the new broadband order. Not nice, expensive, and lack of internet for a day or even a week in some cases.
So please - think of the broadband before ceasing that old fax line.
We can do broadband only phone lines to support the broadband (including taking over your old fax line) for as little as £10/month, and then there is one bill and one point of contact for faults...
I think we'll stop publishing a fax number now as well. The one thing people fax is a "tag change form" for domains, and that can just as easily be scanned or photographed on a camera phone and emailed.
